A private Pennsylvania based diagnostics company Abraxis found glyphosate residues in 41 of 69 honey samples that it tested for the herbicide, according to Reuters news service. Several of the brands that tested positive were organic.
But why would honey have glyphosate in it if the chemical is not used in beekeeping?
Bee keepers and experts say that the honey can become contaminated when bees are within a few miles of farms where glyphosate is used.
FDA testing of three samples showed two of them below that amount, and one sample at more than twice that level.
According to Monsanto, the company that makes the herbicide Roundup, ingesting trace amounts of glyphosate poses no risk to human health.
