Interagency MOU Addresses Chemical Contaminants in Meat, Poultry, and Egg Products
In a move described as advancing the Make America Healthy Again (MAHA) initiative, the Department of Agriculture (USDA), Department of Health and Human Services (HHS), and EPA have updated a memorandum of understanding (MOU) addressing drug residues, pesticide residues, and chemical contaminants in meat, poultry, and egg products.
Announced July 10, 2026, the MOU is intended to coordinate federal activities concerning chemical residues and contaminants that have the potential to adulterate those foods. It supersedes a prior 1984 agreement between the same agencies.
According to a USDA press release, as part of the effort, USDA’s Food Safety and Inspection Service (FSIS) has implemented a new laboratory method to monitor levels of 18 heavy metals in foods. USDA says that elevated levels will lead to further assessment and possible regulatory response. The press release adds that FSIS will “expand its surveillance for heavy metals to include processed foods, such as sausages and ready-to-eat meals, which combine ingredients from multiple sources.”
Coordinating Federal Oversight of Chemical Residues
FSIS primarily oversees the safety and regulation of meat, poultry, and egg products and tests these products for chemical residues through programs such as the National Residue Program. FDA oversees most other foods, live food-producing animals before slaughter, animal food, and animal drugs. EPA regulates pesticides and establishes allowable pesticide residue levels in food, including food for food-producing animals.
Under the MOU, FSIS, FDA, and EPA will coordinate on sampling and testing, tolerances and screening levels, and potential regulatory violations. Among other things, FSIS will provide FDA with weekly residue reports and keep FDA and EPA informed of its sampling and testing programs. FDA and EPA will also notify FSIS when they establish or amend certain tolerances, exemptions, action levels, or safe levels that may relate to FSIS-regulated products.
The agencies also agree to notify one another of information concerning the actual, suspected, or anticipated presence of chemical residues or contaminants that may constitute or result in violations of applicable federal food safety laws. FDA will review reports of potentially adulterated food and, when appropriate, investigate the circumstances that may have caused food-producing animals to be exposed before slaughter. EPA will similarly review reports of pesticide misuse or other potential violations and, when appropriate, investigate or refer the matter to the appropriate state enforcement authority.
A Senior Executive Council with representatives from each of the three agencies will oversee the arrangement and meet at least annually. The MOU also establishes procedures for sharing confidential and non-public information among the agencies, subject to applicable confidentiality requirements.
