The residue layer is real
FDA's FY 2023 pesticide residue monitoring report says the agency tested 224 animal-food samples for 781 different pesticides and selected industrial compounds. That alone should end the fantasy that pesticide exposure is somehow outside the pet-food story.
The same report says most sampled animal food was compliant with federal residue rules, which is important context. The public point is not to fake a poisoning panic. It is to acknowledge that residues, tolerances, and storage chemistry are part of the system.
Contamination findings are not hypothetical either
FDA's June 18, 2025 warning letter to Answers Pet Food says four sampled retail lots contained Salmonella, Listeria monocytogenes, or both. The same letter says investigators found Listeria on seven surfaces in the facility, including food-contact surfaces.
That does not prove every pet food is unsafe, but it does prove the public should pay attention when brands sell themselves on freshness, raw purity, or artisanal trust.
The label still withholds a lot
AAFCO says ingredients are listed in descending order by weight, but the ingredient list does not quantify the absolute amount of each ingredient. That matters because consumers often read the label as if it reveals the full formula when it does not.
FDA's own complaint-reporting page also tells owners to keep the original package, lot number, and storage details because that evidence often matters more than the front-of-bag story.
What is still not proved
This page does not claim commercial pet food has been proved to be driving a broad rise in cancer across pets. That is a much bigger scientific claim than the current public record supports.
What the record does show is enough to justify scrutiny: residues are monitored, products do get flagged, contamination does happen, and diet-linked disease questions have reached the level of FDA investigation before.
