Why did 1996 law change Delaney for pesticide leftovers, and what tests backed it?

Research question: What do FDA Federal Register notices and docket records show about the 1996 FQPA removal of pesticide residues from the Delaney clause, and what toxicological data were cited in the rulemaking?

The verified facts state that the 1996 FQPA eliminated the Delaney clause, which had barred pesticide residues that cause cancer in animals or humans ¹⁷. They contain no Federal Register notices or docket records, and the EPA summary of the Act does not mention the Delaney clause, those notices, those dockets, or any toxicological data cited in the rulemaking ⁶. The only toxicological source named is a 1993 National Academy of Sciences report on pesticides in infants' and children's diets, which the EPA has cited as a catalyst for the FQPA ⁵. The newest fact is dated August 1996, so the record is about 30 years old as of October 2026 and may not reflect later rulemaking or docket activity ³⁶.
