- Delaney clause
- "the Secretary of the Food and Drug Administration shall not approve for use in food any chemical additive found to induce cancer in man, or, after tests, found to induce cancer in animals."
The Delaney Clause was invoked in 1959 by the Secretary of the Department of Health, Education and Welfare when the cancer-causing herbicide aminotriazole was discovered on cranberry plants in Oregon and Washington (see Cranberry scare of 1959). Taking place the week of Thanksgiving, the announcement was referred to by many in the cranberry industry as "Black Monday" − sales plummeted, even though many government officials attempted to defuse the scare by declaring their intention to eat cranberries anyway. This episode is regarded as one of the first modern food scares based on a chemical additive.
The Delaney Clause applied to pesticides in processed foods, but only when residues of a cancer causing pesticide increased during processing; for example when more of a pesticide was present in ketchup than in the raw tomatoes used to make it. (It never applied to pesticides in raw foods.) In 1988 the United States Environmental Protection Agency eased restrictions on several pesticides which posed a "de minimis" risk to humans. This change was challenged by the Natural Resources Defense Council, and overturned in 1992 by the Ninth Circuit Court of Appeals.
Pesticide use was removed from the Delaney Clause in 1996 by an amendment to Title IV of the Food Quality Protection Act of 1996 (P.L. 104-170, Sec. 404).
The Delaney prohibition appears in three separate parts of the FFDCA: Section 409 on food additives; Section 512, relating to animal drugs in meat and poultry; and Section 721 on color additives. The Section 409 prohibition applied to many pesticide residues until enactment of the Food Quality Protection Act of 1996. This legislation removed pesticide residue tolerances from Delaney Clause constraints.
Many foods contain natural substances which are carcinogenic, for example safrole, which occurs in sassafras and sweet basil. Even these substances are covered by the Delaney clause, so that, for example, safrole may not be added to root beer in the USA.
