Claim Review: McDonald's Potatoes and Pesticide Use

The claim that McDonald's insists on using russet burbank potatoes with no blemishes, requiring the use of a toxic pesticide called Monitor, has been circulating widely. Let's break down this claim and examine its validity.
Firstly, it is true that McDonald's has specific standards for the potatoes used in their french fries. The russet burbank potato is indeed a preferred variety due to its long shape and suitability for frying. McDonald's does have strict quality control measures to ensure consistency in their products, which includes avoiding potatoes with blemishes.
Net necrosis is a common defect in russet burbank potatoes, often caused by aphids. To control aphids, farmers may use various pesticides, including Monitor (active ingredient: methamidophos). Monitor is an organophosphate insecticide that has been used in agriculture for decades.
The claim that Monitor is so toxic that farmers won't venture into their fields for five days after spraying is where the claim becomes more complex. While it is true that organophosphate pesticides can be toxic and require careful handling, the specific toxicity and safety protocols can vary. The Environmental Protection Agency (EPA) has guidelines for the safe use of pesticides, including re-entry intervals for workers. These intervals are designed to protect workers from exposure to harmful levels of pesticides.
However, the claim that farmers won't venture into their fields for five days specifically due to Monitor's toxicity lacks direct evidence. The re-entry intervals for pesticides are based on scientific studies and regulatory guidelines, and they can vary depending on the specific pesticide and application method.
In conclusion, while it is true that McDonald's has strict quality standards for their potatoes and that pesticides like Monitor are used to control aphids, the claim about the extreme toxicity of Monitor and the specific re-entry interval of five days is not fully supported by available evidence. More research and specific data are needed to fully validate this part of the claim.
