U.S. consumer groups, scientists and food companies are testing substances ranging from breakfast cereal to breast milk for residues of the world’s most widely used herbicide on rising concerns over its possible links to disease.
The focus is on glyphosate, the active ingredient in Roundup. Testing has increased in the last two years, but scientists say requests spiked after a World Health Organization research unit said last month it was classifying glyphosate as “probably carcinogenic to humans.”
“The requests keep coming in,” said Ben Winkler, laboratory manager at Microbe Inotech Laboratories in St. Louis. The commercial lab has received three to four requests a week to test foods and other substances for glyphosate residues. In prior years, it received only three to four requests annually, according to its records.
Monsanto Co, the maker of Roundup, on April 1 posted a blog seeking to reassure consumers and others about glyphosate residues.
“According to physicians and other food safety experts, the mere presence of a chemical itself is not a human health hazard. It is the amount, or dose, that matters,” Monsanto senior toxicologist Kimberly Hodge-Bell said in the blog. Trace amounts are not unsafe, she stated.
There are numerous studies that have determined glyphosate to be safe, but several others have linked it to human health ailments. Critics say they fear that glyphosate is so pervasive in the environment that extended exposure even to trace amounts can be harmful.
