Farmed Salmon Just as Toxic to Human Health as Junk Food

(Beyond Pesticides, June 16, 2022) Farmed salmon serves as an inferior food source, accumulating more toxic chemicals in fatty tissue with fewer healthy nutrient properties based on a study from the University of Bergen, Norway and Alternative Medicine Review. However, the issue of toxic chemical contamination in fish dates back decades with investigations demonstrating high levels of persistent organic pollutants (POPs), including polybrominated diphenyl ethers (PBDEs) flame retardants restricted or banned in the U.S. and U.K., polychlorinated biphenyl (PCBs), dioxin (a by-product of pesticide manufacturing), and ethoxyquin (a pesticide preservative in fish feed). The aquaculture industry (e.g., farmed seafood/fish) repeatedly faces sustainability issues, failing to adhere to environmental regulations and threatening marine health. Extensive use of pesticides in local marine ecosystems has induced coastal habitat loss and increased genetic and health risks to wild marine populations. Moreover, insecticides used to kill salmon parasites (e.g., fish lice) has led to widespread disease persistence and pest resistance. Marine species biodiversity is rapidly declining due to overfishing, global warming, pathogens, and pollution. Thus, further biodiversity loss can change aquatic and terrestrial ecosystem functions and reduce ecosystem services. Food analysis results find the consumption of farmed salmon fillets contributes to higher rates of metabolic disorders, including diabetes and obesity. These farmed salmon also contain levels […]

Beyond Pesticides Makes Science-based Case that It Is Imperative to Phase Out Pesticides in a Decade

The organic solutions to problems highlighted in the latest issue of Pesticides and You—based on the importance of healthy ecosystems and public health protection—are within reach, and the data creates an imperative for action now that phases out pesticides within a decade, while ensuring food productivity, resilient land management, and safe food, air, and water. (Beyond Pesticides, April 15, 2022) The current issue of Pesticides and You, RETROSPECTIVE 2021: A Call to Urgent Action, is a look at a year of science, policy, and advocacy that informs both the existential problems that the U.S. and the world are facing due to toxic pesticide dependency, and solutions that can be adopted now. The information in this issue captures the body of science that empowers action at the local, state, and federal level, and provides a framework for challenging toxic pesticide use and putting alternatives in place. The issue finds that 2021 was a pivotal year in both defining the problem and advancing the solution. This year in review is divided into nine sections that provide an accounting of scientific findings documenting serious pesticide-induced health and environmental effects, disproportionate risk to people of color and those with preexisting conditions, regulatory failures, at the same time […]

Ocean Health: First Reports of Salmon Lice Resistance in the Pacific Ocean Threatens Local Ecosystems

(Beyond Pesticides, April 12, 2022) A recent study published in Scientific Reports warns that parasitic salmon lice (Lepeophtheirus salmonis) in Pacific Ocean open-net fish farming operations are becoming resistant to emamectin benzoate (EMB), an active ingredient used to control salmon lice population in North America, both in the U.S. and British Columbia, Canada. Previously, researchers believed parasitic salmon lice only had high rates of chemical resistance in the Atlantic region due to the mixing of farmed and wild salmon. However, Pacific salmon lice are exhibiting similar rates of decreased sensitivity to EMB from various sources, including a decrease in the wild Pacific salmon population, overuse of chemical treatments, and reliance on single chemical treatments. The aquaculture industry (e.g., farmed seafood/fish) repeatedly faces sustainability issues, failing to adhere to environmental regulations and threatening marine health. Extensive use of pesticides to rid the parasite has led to widespread resistance to multiple pesticides, prompting increasing infection rates among North Atlantic salmon populations. These parasites endanger both farmed salmon and wild salmon, in addition to other local species of fish. In this context, pesticide treatments contributes to resistance among lethal pest populations, especially in ecologically vulnerable and interconnected ecosystems like ocean basins. The researchers caution, “Salmon […]

Chemicals, including Pesticides, in Wastewater Discharge Contaminate Oysters in Pacific Northwest

(Beyond Pesticides, July 08, 2021) A Portland State University (PSU) study finds oysters of varying distances from wastewater discharge pipes along the Oregon and Washington state coast contain low levels of chemical contaminants. Although wastewater treatment facilities clean water draining from sinks and toilets, the process does not adequately remove all contaminants. The process can leave behind pharmaceutical drugs and personal care products (e. g., shampoos, make-up, deodorant) residues in treated water. PSU has already found that pesticides from the forestry industry threaten clams, mussels, oysters (bivalves) along the Oregon coast. Marine ecosystem pollution is difficult to track and measure, and pesticide regulations can invoke variations in water quality requirements through discrepancies in buffer zones and application concentrations. The combined presence of pesticides, medicine, and personal care products in aquatic environments has direct implications for species and ecosystem health and indirect consequences for human well-being. Therefore, studies like this can help government and health officials develop strategies to reduce the number of chemicals entering aquatic ecosystems, with researchers noting officials can “better understand whether contaminant exposure affects oyster condition.” Researchers wanted to evaluate how proximity to wastewater facilities affects variations in aquatic pollution. Thus, scientists transplanted one-week-old Pacific oysters along the Oregon and […]

Threat to Ocean Health: Pesticide Resistant Fish Lice Plague the North Atlantic Ocean

(Beyond Pesticides, June 3, 2021) A report published in Royal Society Open Science finds pesticide-resistant parasitic lice (Lepeophtheirus salmonis) are endangering wild and farmed fish populations in the North Atlantic. Extensive use of pesticides to rid the parasite has led to widespread resistance to multiple pesticides, prompting increasing infection rates among North Atlantic salmon populations. Overexploitation of wild fish and other ocean organisms has depleted seafood stocks globally. Some fisheries market aquaculture practices, like fish/seafood farming, as a solution to overfishing. However, the aquaculture industry repeatedly faces sustainability issues and fails to adhere to environmental regulations that threaten marine health. The oceans are essential to human health and well-being, feeding billions, supporting millions of jobs, and supplying medicinal materials. However, environmental contaminants like pesticides have profound impact on the ecosystem and the inhabitants. Therefore, it is necessary to understand how pesticides can influence resistance among lethal pest populations, especially in ecologically vulnerable and highly interconnected ecosystems like ocean basins. The authors of the report caution, “These results demonstrate the speed to which this parasite can develop widespread multi-resistance, illustrating why the aquaculture industry has repeatedly lost the arms race with this highly problematic parasite.” Over the past two decades, organophosphate and pyrethroid insecticides […]

Take Action: Tell Congress to Save Our Oceans from Trump’s Executive Order

(Beyond Pesticides, June 15, 2020)  On May 7, President Trump issued an executive order (EO) purporting to “promote American seafood competitiveness and economic growth,” while, in fact, permitting offshore aquaculture in federal waters with reduced environmental safeguards. Instead, we need stronger federal regulation in order to protect the environment and public health. This EO adds to the Trump Administration’s shameful record of dismantling environmental protections, failing to enforce those that do exist, undermining science, and weighing agrochemical and other industry interests over those of the public and the environment. The EO will further erode regulations that have governed the operation of so-called “fish farms” and open enormous marine areas to exploitation by this industry. Tell Congress to save our oceans. U.S. aquaculture is a $1.5 billion industry, with almost 3,000 operations. Regulation of aquaculture is shared by a number of federal, state, and local agencies. Much of the regulation is at the state and local level because each state and locality may regulate permitting based on zoning, water use, waste discharge, wildlife management, processing, and other aspects of aquaculture operations.  Trump’s EO reduces federal regulation by designating the National Oceanic and Atmospheric Administration (NOAA) as the lead agency in the […]

Presidential Executive Order Loosens Environmental Restrictions on Fish Farms, Adds to Degradation of Waterways

(Beyond Pesticides, June 1, 2020) The President issued another executive order, on May 7, that continues his administration’s dissembling on matters that affect the well-being of everyday Americans. This EO (executive order) purports to “promote American seafood competitiveness and economic growth.” The reality, as the Center for American Progress reports, is that the “bulk of the Trump administration’s new executive order sets up a structure for permitting of offshore aquaculture in federal waters with short timelines and few environmental safeguards.” This EO will further erode regulations that have governed the operation of so-called “fish farms,” and open enormous marine areas to exploitation by this industry. Beyond Pesticides has argued for more-protective regulation of the aquaculture industry, considering the variety of pesticides and chemical inputs it uses, and the impacts on local ecosystems. The U.S. Department of Agriculture (USDA) defines aquaculture as any “farming of aquatic organisms, including baitfish, crustaceans, food fish, mollusks, ornamental fish, sport or game fish, and other aquaculture products. Farming involves some form of intervention in the rearing process, such as seeding, stocking, feeding, protection from predators, etc. Fish, crustaceans, mollusks, and other aquatic products caught or harvested by the public from non-controlled waters or beds are considered […]

Pesticides Contaminate Fish Farms, Fish Farm Fined

(Beyond Pesticides, May 16, 2018) Northern Harvest Sea Farms, an ocean-based fish farm in New Brunswick, Canada, was appeared in court yesterday to answer legal charges stemming from the off-label use of an unnamed pesticide added to its operations to combat severe sea lice outbreaks. The company holds nine licenses for farmed Atlantic salmon cages on the Bay of Fundy, as well as for fish farms off the Newfoundland coast. Sea lice outbreaks are a common at over-crowded, ocean-based fish farms because such facilities afford the optimum conditions for rapidly reproducing and spreading lice. In response, some companies have turned to using illegal and off-label pesticide applications to stave off the problem, which causes huge farmed salmon kills. The company was issued a $12,000 fine that was challenged as inadequate by the Grand Manan Fishermen’s Association. Bonnie Morse, project manager for the association told Canadian Broadcasting Corporation (CBC) news, “I think any time there’s a fine that’s a deterrent to illegal activity, it should be an actual deterrent to the activity,” said Morse. “When you’re looking at $1.5 million worth of fish, their actions speak for themselves.” Maria Recchia, the executive director of the Fundy North Fishermen’s Association, questioned the allowance of fish […]

Lawsuit Filed to Stop Expansion of Aquaculture Industry that Decimates Marine Life

(Beyond Pesticides, August 23, 2017) The Center for Food Safety (CFS) filed a federal lawsuit to stop the U.S. Army Corps of Engineers from moving forward with an expansion of industrial shellfish aquaculture on the Washington state coast without any water quality or marine life protections from pesticide use and habitat loss. This is just the latest in efforts to protect sensitive coastal areas in Washington from shellfish farming that is contributing to increased pesticide use and environmental degradation. The lawsuit, filed in the U.S. District Court for the Western District of Washington earlier this month, challenges the U.S. Army Corps of Engineers (Corps) issuance of a nationwide permit (NWP 48), which, according to the suit, “greenlights a massive expansion of shellfish aquaculture with entirely inadequate protections.” The Corps has a duty to protect public water from adverse impacts, but potential environmental impacts have not properly assessed or considered, the suit claims, in violation of the Corps’ environmental protection mission. The lawsuit argues that the Corps, when it approved the Washington state permit, violated numerous environmental laws, including the Clean Water Act, National Environmental Policy Act, and Administrative Procedure Act. According to CFS, the permit issued will allow shellfish aquaculture acreage […]

Washington Oyster Growers Request Approval to Apply Neonicotinoid in Aquatic Environments

(Beyond Pesticides, July 6, 2017) The Washington State Department of Ecology (Ecology) is evaluating a new permit application for the use of imidacloprid, a toxic neonicotinoid, to combat a growing native population of burrowing shrimp that threatens oyster beds in Willapa Bay and Grays Harbor in Washington state. The application was recently submitted to Ecology by a group of oyster farmers from the Willapa Grays Harbor Oyster Growers Association (WGHOGA), who “propose to use the pesticide to treat tide lands to support their aquaculture practices.” Imidacloprid is known to be toxic to bees and aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. In April 2015, much to the dismay of activists and concerned local residents, Ecology approved a permit submitted by oyster farmers for the use of imidacloprid to combat burrowing shrimp in these aquatic ecosystems. But with a nationwide public outcry, the permit was withdrawn in May 2015. The recent request that was submitted differs in several ways from this 2015 permit, including: The new permit proposes treating 485 acres in Willapa Bay and 15 acres in Grays Harbor, compared to 2,000 acres combined from both water bodies in the 2015 permit. The oyster farmers […]

Proposal to Restrict Pesticide Use Near CA Schools, Criticized as Weak, Open for Public Comment

(Beyond Pesticides, October 3, 2016) On Friday, the California Department of Pesticide Regulation (CDPR) released a rule titled, Pesticide Use Near Schoolsites, that proposes limited restrictions for certain agricultural pesticide applications near schools and child day care facilities. CDPR, whose proposal  has been criticized by advocates as not adequately protective of workers and communities, is accepting public comments on the proposal until November 17, 2016. The  proposed rule, effective October 1, 2017, will require farmers to notify public schools and child day care facilities when “certain pesticide applications made for the production of an agricultural commodity near a school site are planned in the coming year and also a few days prior to the applications.” For pesticides applied via aircraft, airblast sprayer, sprinkler chemigation, and fumigation, there must be a minimum ÂĽ  mile buffer around the school or child day care facility. While the move by CDPR is a step in the right direction, it is not rigorous enough and does not adequately protect the most vulnerable populations from pesticide exposure, according to advocates. The rule does not include private K-12 schools or family day care homes, a move that according to CDPR documents is due to the potential for […]

Intersex Fish at National Wildlife Refuges Considered for Further Study

(Beyond Pesticides, February 16, 2016) Last Thursday, officials reported that federal scientists for the U.S. Fish and Wildlife Service (FWS) are recommending follow up studies for a portion of the Wallkill River in Sussex County, NJ, in addition to five other national wildlife refuges in the Northeast that were previously found to contain small-mouth bass with intersex characteristics. A study conducted  by FWS and the U.S. Geological Survey (USGS) points out that smallmouth and largemouth bass are showing intersex features, but researchers have  not pinpointed the cause. Scientists hope a follow up study will provide answers. Intersex fish and other species are  characterized  by one sex exhibiting traits  of the opposite sex. In the case of the FWS/USGS study, researchers found testicular oocytes ””female eggs found inside male testicles””in male smallmouth and largemouth bass. The source of intersex effects  can be hard to pinpoint, but pesticides are often cited as a cause given that they widely pollute waterways that  fish populate. Those chemicals have properties that disrupt the endocrine system and affect the reproductive system, causing development issues such as testicular oocytes. According to the USGS press release for the study, “Estrogenic endocrine-disrupting chemicals are derived from a variety of […]

Bayer Refuses to Cancel Insecticide Toxic to Aquatic Life

(Beyond Pesticides, February 9, 2016) Last week, Bayer CropScience reneged on an agreement with the U.S. Environmental Protection Agency (EPA) to voluntarily cancel the conditionally registered insecticide flubendiamide if  the agency  received  data that  identified adverse ecological effects. Based on the data, EPA found that the chemical causes “unreasonable adverse effects” to benthic organisms living in sediment near agricultural fields. Bayer’s defiance in the face of EPA’s finding  points to  a fundamental  weakness in  the agency’s conditional pesticide registration process, which allows toxic chemicals onto the market without a complete and comprehensive assessment  of their  potential  harm, in this case to  wildlife and the vital ecosystem services they provide. In 2008, EPA granted Bayer a “conditional” registration for flubendiamide, a classification that allows a new pesticide to be registered and used in the field, despite outstanding data points on its toxicological impact. In this case, original data submitted to EPA by Bayer showed concern over the effect of the chemical and its breakdown product on freshwater benthic invertebrates, species such as crustaceans and aquatic insects that  live in stream sediment and provide important ecosystem services such as decomposition and nutrient cycling. In response, rather than declining to proceed with registration […]

WA Oyster Growers Request Approval to Spray Neonicotinoid Pesticides in Bay, Despite Public Opposition

(Beyond Pesticides, January 13, 2016) Last Friday, the Willapa Grays Harbor Oyster Growers Association (WGHOGA) in Washington State sent a 71-page request to the Washington Department of Ecology (Ecology) asking state regulators to approve  a permit to  spray neonicotinoid insecticides  that are having devastating effects on the ecosystems worldwide. Yet, WGHOGA is pursuing a single-minded approach to chemically control the shrimp that are hurting their oyster crops, while using chemicals that the preponderance of science finds cause ecosystem imbalance. In  April 2015, much to the dismay of activists and concerned local residents, Ecology approved a permit for the use of imidacloprid (a neonicotinoid) to combat a growing native population of burrowing shrimp that threatens  valuable shellfish (oyster) beds in Willapa Bay and Grays  Harbor. But, with a  nationwide public outcry, the permit was withdrawn in May 2015. Ecology sent KING 5, a local Washington news agency, the below statement last Friday: “We received the permit application this morning from the Willapa Grays Harbor Oyster Growers Association to use imidacloprid on shellfish beds. It will take some time for us to review the 71-page application. On May 3 (2015) the Oyster Growers Association asked Ecology to withdraw their permit. Since then, […]

Herbicides and Endocrine-Disrupting Chemicals Linked to Decline of Smallmouth Bass

(Beyond Pesticides, December 18, 2015) One of the most likely causes for the population decline of smallmouth bass in the Susquehanna River are endocrine-disrupting compounds and herbicides, concludes a multi-agency, multi-year study of one of the most complex river systems in Pennsylvania. The Pennsylvania Department of Environmental Protection (DEP) and the Pennsylvania Fish and Boat Commission (PFBC), along with nearly 50 participants and six partner agencies, released findings on Monday that narrow the likely causes from an initial field of 14 candidates to two. PFBC also found that pathogens and parasites are probable contributing factors. Following a smallmouth bass (SMB) population crash in 2005, and additional observed maladies, such as tumors and lesions on SMB, the team used ground-breaking monitoring strategies to collect more than 30,000 water quality records annually, along with review of existing research to isolate the possible causes keeping young-of-the-year (YOY) SMB from growing to adulthood. The study provides evidence to what Beyond Pesticides suspected back in May, when PFBC confirmed that a rare malignant tumor was found for the first time on a SMB caught by an angler back in the summer of 2014. Though the findings at the time did not point to a specific […]

Genetically Engineered Salmon without Labeling Approved by FDA

(Beyond Pesticides, December 1, 2015) Last month, the U.S. Food and Drug Administration (FDA) approved, without a labeling requirement, a genetically engineered (GE) salmon designed to grow faster and come to market quicker than other farmed salmon. The fish, dubbed AquAdvantage by its developer, Massachusetts-based biotechnology firm AquaBounty, has been the center of considerable controversy as it represents the first GE animal approved for commercial sale and human consumption. While FDA has declared the fish safe to eat, and AquaBounty argues the fish will help feed the world, opponents stress that the potential adverse effects of the technology have not been properly vetted, and consumers will have no way to tell whether the salmon they purchase at the store is the engineered AquAdvantage product. Draft guidelines released by FDA when the salmon was approved do not require retailers to inform consumers that the fish is GE. Instead, the agency provided examples of voluntary statements, such as “genetically engineered,” or “This salmon patty was made from Atlantic salmon produced using modern biotechnology,” that producers  can consider using. The FDA policy makes it virtually impossible for shoppers wishing to avoid the GE fish to make an informed decision at the point of […]

Pesticides Bound to Particles and Not Detectable in Water Harm Aquatic Organisms

(Beyond Pesticides, November 23, 2015) Commonly-used pesticides can impact aquatic species over multiple weeks, even when chemicals are no longer detectable in water nor  monitored by regulators, according to new research. The study, titled A long-term assessment of pesticide mixture effects on aquatic invertebrate communities,  published in the journal Environmental Toxicology and Chemistry, investigates the long-term effects on aquatic invertebrate communities of commonly-used insecticides: two pyrethroids (permethrin and lambda-cyhalothrin) and an organophosphate (chlorpyrifos). Pesticide applications were based on environmentally relevant concentrations and lethal concentrations (a concentration required to kill a certain percentage of animals tested) ranging from 10% (LC10) to 50% (LC50). Researchers made repeat applications in order to mimic runoff events in a multiple grower or homeowner watershed. The results indicate that insecticide mixtures continue to impact natural systems over multiple weeks, even when bound to particles and no longer detectable in water. Combinations of indirect and direct effects caused consequences across the food chain. Pyrethroids rapidly dissipated from the water column, whereas chlorpyrifos was detectable even six weeks after application. “The effects we observed indicate that many species were affected at a sublethal level,” said Simone Hasenbein, Ph.D., lead author of the study tells Phys.org. “Thus, populations exposed […]

Tests Confirm Rare Cancer in Susquehanna River Smallmouth Bass

(Beyond Pesticides, May 7, 2015) The Pennsylvania Fish and Boat Commission (PFBC) has confirmed that a rare malignant tumor was found on a smallmouth bass caught in the Susquehanna River by an angler late last summer. The finding was confirmed by two independent laboratory tests, including the U.S. Fish and Wildlife Service (FWS) and the Aquatic Animal Health Laboratory at Michigan State University.  Although it only represents one individual fish from the overall population, it provides additional evidence —which includes the prevalence of intersex fish discovered last summer”” that the health of the fish community residing in the river is being compromised, according to PFBC executive director John Arway. Though the findings do not point to a specific cause for the cancer found on the smallmouth bass (SMB), agricultural pesticides, particularly endocrine disrupting chemicals, that have been found in the watershed, likely play a part in the rampant disease issues in SMB in the Susquehanna River. “As we continue to study the river, we find young-of-year and now adult bass with sores, lesions and more recently a cancerous tumor, all of which continue to negatively impact population levels and recreational fishing,” Mr. Arway said. “The weight-of-evidence continues to build a […]

Toxic Imidacloprid To Be Sprayed on Oyster Beds in Washington Bays

(Beyond Pesticides, April 29, 2015) Much to the dismay of activists and concerned local residents, the Washington Department of Ecology (Ecology) approved a permit for the use of imidacloprid (a neonicotinoid) to combat a growing native population of burrowing shrimp that threatens valuable shellfish (oyster) beds in Willapa Bay and Grays Harbor in Washington state. Imidacloprid is known to be toxic to bees but is also toxic to aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. The shellfish industry is important to the Pacific Northwest, injecting an estimated $270 million or more into the region’s economy, and providing jobs for many. Washington’s tidelands, especially those in Willapa Bay, have been particularly productive for more than 100 years. However, according to shellfish growers, the burrowing shrimp (ghost shrimp, Neotrypaea californiensis,  and mud shrimp, Upogebia pugettensis) undermines the industry. The creatures burrow into shellfish beds, making the beds too soft for shellfish cultivation. Their burrowing churns the tidelands into a sticky muck, smothering the oysters. After several years of deliberations and studies, Ecology identified imidacloprid as its  preferred choice for eradicating the shrimp. According to the agency, imidacloprid disrupts the burrowing shrimps’ […]

Changes to Canadian Aquaculture Rule Raises Pesticide Concerns

(Beyond Pesticides, February 20, 2015) A broad-based coalition is urging Canada’s Prime Minister Stephen Harper to put a stop to proposed changes to federal aquaculture regulations, citing damage to the environment and existing businesses. The proposed amendments to the federal Fisheries Act would exempt the aquaculture industry from provisions that “prohibit the release of deleterious substances into water frequented by fish.” Coalition members are worried that the changes will result in pesticides routinely being dumped into the Bay of Fundy,  located between the Canadian provinces of Nova Scotia and New Brunswick, and remove Environment Canada’s role in aquaculture activities, said spokeswoman Maria Recchia, the executive director of the Fundy North Fishermen’s Association. Aquaculture, which refers to the breeding, rearing, and harvesting of aquatic organisms such as fish, shellfish, and plants, provides half of the world’s seafood. According to  Food and Water Watch, offshore aquaculture follows an industrial agriculture model which grows thousands of animals in a confined environment. For fish, however, this confined space is in the ocean, meaning all of the waste products from the operation flow directly into the ocean. This includes excess feed and chemicals that are used, such as antibiotics and pesticides, to treat or prevent […]

Study Finds EPA Favors Industry in Pesticide Safety Evaluations

(Beyond Pesticides, September 5, 2014) A study published in a scientific journal finds that the U.S. Environmental Protection Agency (EPA) favors the chemical  industry when making determinations on pesticide safety. Under the Federal Insecticide Fungicide and Rodenticide Act (FIFRA), EPA conducts  risk assessments to determine whether a new or existing chemical is eligible for registration or reregistration and therefore able to enter or remain on the market. The study’s conclusions raise serious concerns for both environmental and human health protection because of EPA’s practice of inviting bias and underestimating potential harm. The study, which will be in the October issue of BioScience, highlights the case of atrazine, an herbicide that has been linked to cancer, endocrine disruption, birth defects, and reproductive effects. In their study, Michelle Boone, Ph.D., of Miami University, and her colleagues find that most pesticide toxicity tests used in risk assessments are conducted by pesticide manufacturers themselves. The authors contend that this can result in conflicts of interest. Additionally, strict methodological criteria, such as the types of containers in which exposed specimens are raised, often mean that potentially relevant studies are barred from EPA’s assessment process. The agency reassessed atrazine  based on a sole, manufacturer-funded study, finding […]

Scientist Warns of Ecological Effects Associated with Lawn Care Pesticide Runoff

(Beyond Pesticides, June 9, 2014) A recent talk given by Donald Weston, PhD, a professor emeritus in UC Berkeley’s Department of Integrative Biology, to a community group in San Jose, California warned residents about the dangers that  lawn care insecticides present to  local aquatic life. The talk focused on the problems synthetic pyrethroids and fipronil can have on Hyalella azteca and Chironomus dilutes. Increasing levels of pesticide runoff in local stream systems have not only led to decreased populations of these aquatic crustaceans, but also populations that have become resistant to pesticides. Aquatic invertebrates are extremely sensitive to pesticide runoff and different states around the country have struggled with creating pesticide regulations that foster a healthy aquatic ecosystem. A good way to reduce pesticide runoff is to transition away from toxic land care methods and adopt organic practices. Hyalella crustaceans, a tiny shrimp-like animal, are hypersensitive to pyrethroids, which are a class of insecticides used by professional lawn care companies and found in common products like Raid and mixed with fertilizer products like Scotts Turf Builder under the name SummerGuard. Chironomus dilutes, a red worm-like invertebrate, is sensitive to fipronil, which is used to kill fleas on dogs and cats […]

(Beyond Pesticides, September 9, 2013) The National Organic Standards Board (NOSB) is now accepting public comments until October 1, 2013 for its upcoming fall meeting, to be held October 22-24, 2013 at the Galt House Hotel in Louisville, KY  (140 North Fourth St., Louisville, KY, 40202).

Written comments on the proposals can be submitted until 11:59 pm on Tuesday, October 1, 2013 at regulations.gov. You can also attend the NOSB meeting in person […]
