Two popular types of the pesticide neonicotinoid used widely on America’s foods may cause brain impairment and should be restricted, according to a recent study by a team of European scientists.
As previously reported by Off The Grid News, neonicotinoids  are among the primary ingredients in chemical pesticides and herbicides manufactured by biotech giants like Monsanto and DuPont. An earlier study published by the journal Ecology linked the chemical with the unprecedented decline in the honeybee population worldwide.
The European Food Safety Authority  (EFSA) report stated that further restrictions of neonicotinoids is needed because the use of such chemicals “may affect the developing human nervous system of children.” Officials in Europe passed new restrictions on three types of neonicotinoids during the early months of 2013 to help protect the honeybee population. The tiny pollinators are integral to the survival of both human and livestock.
The European scientists believe that the neonicotinoids are safe only on amounts smaller than what are currently allowed by law.
“Acetamiprid and imidacloprid may adversely affect the development of neurons and brain structures associated with functions such as learning and memory,” a press release that accompanied the study states.
The US Environmental Protection Agency (EPA) also conducted a similar study which reportedly showed equally adverse effects on honeybees, but the federal agency has failed to take action on the findings. The European scientists began reviewing the impact of the neonicotinoids imidacloprid and acetamiprid  after a Japanese study prompted safety concerns in 2012.
An excerpt from the neonicotinoids study reads:
One study with rats showed that offspring exposed to imidacloprid suffered brain shrinkage, reduced activity of nerve signals controlling movement, and weight loss. Another rat study found that acetamiprid exposure led to reduced weight, reduced survival, and a heightened response to startling sounds.
Bayer representative Richard Breum dismissed the Japanese neonicotinoids study saying rat cell cultures and not human cells were used during the testing. Bayer profits from the sale of chemical pesticides and herbicides which contain various neonicotinoids. “Imidacloprid has no developmental neurotoxicity potential in humans,” Breum said, according to The New York Times.
A statement released by the European Food Safety Authority reads:
[The study] recognizes the available evidence has limitations and recommends further research be carried out to provide more robust data. [But] health concerns raised in the review of the existing data are legitimate.
The study found that acetamiprid and imidacloprid could negatively impact brain structures and neuron development that are associated with memory and learning. The group wants more stringent controls on the amount of neonicotinoids used in food products. In the United States, both of the chemicals are used with very little regulation.
A total of one-fifth of the crops sampled in America contain imidacloprid, including 60 percent of cauliflower and broccoli produce, according to Grist. Approximately 10 percent of the crops sampled in the review tested positive for acetamiprid, including 50 percent of summer squash.
A New York Times report stated that imidacloprid is one of the “most popular” insecticides used in consumer and agricultural products. Bayer developed the neonicotinoid and it is the active ingredient in the company’s Advanced Citrus and Vegetable Insect Control products. The biotech product is sold around the world, including in Home Depot stores throughout the United States.
Nisso Chemical, a German branch of a Japanese company, developed Acetamiprid with the assistance of Bayer. The neonicotinoid is found in products such as the company’s Ortho Flower, Fruit & Vegetable Insect Killer.
European Food Safety Association spokesman James Ramsay said:
We’re advising that all neonicotinoid substances be evaluated as part of this testing strategy, providing that they show a similar toxicological profile to the two substances we’ve assessed in this opinion.
The lack of attention to the honeybee decline (often referred to as Colony Collapse Disorder) and the potential human and animal health concerns due to the use of neonicotinoids, prompted a group of beekeepers, environmental and food safety organizations to sue the EPA.
As previously noted by Off The Grid News, President Obama has appointed a host of former Monsanto executives  to key positions of leadership in the EPA, FDA and the USDA, prompting some to ponder a possible conflict of interest among those tasked with keeping the food supply and the environment safe. Monsanto also makes neonicotinoid products.
