The Food and Drug Administration, under public pressure to start testing samples of U.S. food for the presence of a pesticide that has been linked to cancer, has some early findings that are not so sweet.
In examining honey samples from various locations in the United States, the FDA has found fresh evidence that residues of the weed killer called glyphosate can be pervasive – found even in a food that is not produced with the use of glyphosate. All of the samples the FDA tested in a recent examination contained glyphosate residues, and some of the honey showed residue levels double the limit allowedin the European Union, according to documents obtained through a Freedom of Information Act request. There is no legal tolerance level for glyphosate in honey in the United States.
Glyphosate, which is the key ingredient in Monsanto Co.'s Roundup herbicide, is the most widely used weed killer in the world, and concerns about glyphosate residues in food spiked after the World Health Organization in 2015 said its cancer experts determined glyphosate is a probable human carcinogen. Other international scientists have raised concerns about how heavy use of glyphosate is impacting human health and the environment.
Records obtained from the FDA, as well as the Environmental Protection Agency and the U.S. Department of Agriculture, detail a range of revelations about the federal government's efforts to get a handle on these rising concerns. In addition to honey, the records show government residue experts discussing glyphosate found in soybean and wheat samples, “glyphosate controversies,” and the belief that there could be “a lot of violation for glyphosate” residues in U.S. crops.
Even though the FDA annually examines foods for residues of many pesticides, it has skipped testing for glyphosate residues for decades. It was only in February of this year that the agency said it would start some glyphosate residues analysis. That came after many independent researchers started conducting their own testing and found glyphosate in an array of food products, including flour, cereal, and oatmeal. The government and Monsanto have maintained that any glyphosate residues in food would be minimal enough to be safe. But critics say without robust testing, glyphosate levels in food are not known. And they say that even trace amounts may be harmful because they are likely consumed so regularly in many foods.
The residue issues are coming into the spotlight at the same time that the EPA is completing a risk assessment to determine if use of this top-selling herbicide should be limited. The agency has scheduled public meetings on the matter Oct. 18-21 in Washington. The EPA's risk assessment report was initially due out in 2015, but still has not been finalized. The agency now says it will be completed in “spring 2017.”
In the records released by the FDA, one internal email describes trouble locating honey that doesn't contain glyphosate: “It is difficult to find blank honey that does not contain residue. I collect about 10 samples of honey in the market and they all contain glyphosate,” states an FDA researcher. Even “organic mountain honey” contained low concentrations of glyphosate, the FDA documents show.
