The U.S. Food and Drug Administration (FDA) has issued its annual Pesticide Residue Monitoring Program Report for FY 2019. We tested for 812 pesticides and industrial chemicals across 4,692 total samples and the majority of samples had pesticide residues below the limits (known as “tolerances”) set by the U.S. Environmental Protection Agency (EPA). These results are consistent with the trend of low levels of pesticide residue violations over the past 8 years.
Growers often use pesticides to protect their crops from insects, weeds, fungi, and other pests. To protect public health, the EPA sets tolerances on the amounts of pesticides, known as pesticide chemical residues, that may remain in or on some foods. The FDA’s role is to ensure that pesticide chemical residues in or on foods comply with the EPA tolerances. We consider a food to be in violation of federal standards when it has pesticide chemical residues above the EPA tolerance, residues of pesticides that have no EPA tolerance, or residues of pesticides that do not have a tolerance exemption for that specific pesticide/commodity combination.
In FY 2019, we tested 4,327 human food samples. We found that 98.7% of the 1,258 domestic and 89.1% of the 3,069 imported samples were in compliance with federal pesticide residue standards. We also found no pesticide chemical residues in 42.4% of domestic and 49.4% of imported human food samples.
Similarly, we tested 365 animal food samples. We found that 98.4% of the 127 domestic and 95.4% of the 238 imported samples were in compliance. We also found no pesticide chemical residues in 40.9% of the domestic and 43.7% of the imported animal food samples.
In FY 2019, we conducted a supplemental analysis to evaluate the effectiveness of our current sampling design which targets commodities and production sources that are likely to be higher risk. Historically, the violation rate for imported foods is higher than for domestic foods so every year approximately 70 percent of the commodities sampled are imports. The FDA also identifies imported foods that warrant special attention (such as increased future sampling) because they have a violation rate of 10 percent or higher and meet other criteria.
For most commodities, our current sampling and analysis strategies capture the commodities that truly warrant special attention. However, we determined that additional sampling is needed for commodities with violation rates near 10 percent or where the number of imports samples collected is relatively low. As a result, the FDA has increased the number of samples requested for FY 2022 sampling for cabbage, lemons, lettuce, and soybeans.
We also analyzed 153 samples of domestic milk, shell eggs, honey, and game meat for pesticides under the “Domestically Produced Animal-Derived Foods” sampling assignment. None of the samples had a pesticide residue violation except for honey, where we found 2 violative samples out of the 62 samples collected. Overall, 88.9% of the samples from this focused assignment contained no residues.
When we identify a domestic food sample that violates the federal pesticide standards, we may issue a warning letter to the responsible grower/manufacturer. We can also take other actions, such as seizing the food to remove it from the market or seeking an injunction to correct the cause of the violation.
When we identify an imported food sample that violates federal pesticide standards, we may place the company and the food on an Import Alert to help prevent the food from entering the country, as appropriate. Products on import alert may be detained without border inspectors physically examining the shipment (known as “Detention Without Physical Examination”).
We employ a three-fold strategy to enforce the EPA’s tolerances for pesticide chemical residues. Through our regulatory pesticide residue monitoring program, we monitor a broad range of domestic and imported commodities. We may also collect samples of specific foods or test for pesticides of special interest, as we did with glyphosate before it was introduced into the routine monitoring program. In addition, we monitor the levels of pesticide chemical residues in food prepared for human consumption in our Total Diet Study (TDS), an ongoing program that monitors contaminants and nutrients in the average U.S. diet.
Together with the EPA and the U.S. Department of Agriculture, we take very seriously our responsibility to keep food free of unsafe levels of pesticide chemical residues. The findings in our 2019 report demonstrate that the levels of pesticide chemical residues are generally below the EPA’s tolerances and are therefore at levels that do not pose a concern for public health.
