LONDON, Dec 17 (Reuters) – European health authorities warned on Tuesday that two insecticides, including a widely-used one made by Bayer, may affect the developing human brain and should be more tightly controlled to limit human exposure.
The products – acetamiprid and imidacloprid – belong to popular class of insecticides called neonicotinoids, which have recently been in the spotlight due to links with plunging populations of bees. Imidacloprid is one of the most widely used insecticides in the world.
In Western Canada imidacloprid is an active ingredient in several neonicotinoid insecticides. These include Admire, Alias, Grapple and Grapple2 for use in potatoes to control Colorado potato beetle, aphids, potato leaf hopper and potato flea beetle. As a grain and oilseed seed treatment it can be found in Gaucho, Sombrero, Raxil WW and Concept.

Alberta crop conditions improve: report
Varied precipitation and warm temperatures were generally beneficial for crop development across Alberta during the week ended July 8, according to the latest provincial crop report released July 11.
The European Union voted in April to ban three neonicotinoids – including imidacloprid which is primarily manufactured by Bayer – for two years amid safety and environmental concerns.
In Tuesday’s move, the European Food Safety Authority (EFSA) recommended guidance levels for exposure to the products be lowered while further research is carried out to provide more reliable data on so-called developmental neurotoxicity.
“Acetamiprid and imidacloprid may adversely affect the development of neurons and brain structures associated with functions such as learning and memory,” EFSA said in a statement from its Rome headquarters.
“Some current guidance levels for acceptable exposure to acetamiprid and imidacloprid may not be protective enough to safeguard against developmental neurotoxicity and should be reduced.”
A spokesman for the European Commission, which asked EFSA to carry out the assessment, said it would give Bayer and the makers of acetamiprid an opportunity to comment on the findings.
“In principle, the next step would then be to amend the reference values,” said Commission health spokesman Frederic Vincent, adding that EU government officials would begin the process at a meeting in March.
In response, Bayer’s CropScience division said it saw no link between imidacloprid and developmental neurotoxicity in humans, and said EFSA had based its concerns on an inconclusive 2012 study that used tests on rat cell cultures.
“EFSA itself recognises the limitations of this publication. Bayer CropScience has also evaluated the publication and can confirm that few conclusions can be drawn from it,” the statement said.
