Is Glyphosate Applied To Idaho® Potatoes?


Is glyphosate (the active ingredient in the broad-spectrum herbicide Roundup) applied at any point in the production of Idaho potatoes?


I passed this question on to our Industry Relations Director and this was his response:

You are correct, glyphosate is a chemical in the herbicide “Round Up” and it’s used on many fields of fruits and vegetables (potatoes included) when needed to control the weeds. It is also only used BEFORE potato planting or right after, but before the potato comes out of the ground.  Since the potato has not emerged yet, it does not absorb and glyphosate.

I can also tell you that for the last 20-25 years, every month the Idaho Potato industry checks our Idaho® Potatoes for pesticide residues and have never found anything to be alarmed about. We do this just for questions like yours. I’m not aware of any other state that does this.

In the United States, we are lucky to have the safest food supply in the world.  This link is a good reference too for those concerned. According to this, I could consume 5,141 servings of potatoes in one day without any effect even if the potatoes have the highest pesticide residue recorded for potatoes by USDA.
