Glyphosate, the active herbicidal ingredient found in most if not all weed killers like Roundup, has been found in dog food. But don’t panic, advises the study, the level is only 0.7 percent of the U.S. glyphosate limit set for humans.
The study was conducted by Brian Richards, senior research associate in biological and environmental engineering, and supported by the Atkinson Center for a Sustainable Future’s Academic Venture Fund. The goal of this study was to determine how much glyphosate was found in crops, surface water in fields, soil and animal feed.
The study determined that the herbicide found its way into pet food through the plant matter included in the food. However, they could not pinpoint which plants had the glyphosate.
Although there is no risk to pets, the long-term consumption of glyphosate has not been studied. Also, my thought is this: While the levels are very low for human consumption, dogs and cats are much smaller than people. Therefore the amount by comparison may be a risk for pets. An average human adult who weighs 150 – 200 lbs. and can tolerate .07% but what about the average medium sized dog who weighs 40 pounds. What about children and pets who weigh less than 40 lbs.?
It seems from the study that there are little or no pet foods that do not have glyphosate in them. Does this mean that other pet food has glyphosate in it? Some pets only eat vegetable or plant products. This is another thing to consider for both humans and animals. More studies are needed.
