Your pet ate their normal food and got sick. Or worse — multiple pets in your home got sick. Could it be the food? Sometimes yes, sometimes no. Here's how to investigate methodically and report concerns properly.
Signs That Food Might Be the Cause
Food-related illness typically presents with:
- Vomiting or diarrhea within 24-48 hours of eating
- Loss of appetite
- Lethargy
- Symptoms in multiple pets in the same household (strong indicator)
- Symptoms that started with a new bag of food
- Mold, off-smell, or unusual appearance in the food itself
For specific contaminants:
- Vitamin D toxicity: Vomiting, increased thirst/urination, loss of appetite, weight loss. Usually develops over days to weeks.
- Salmonella: Vomiting, diarrhea (often bloody), fever, lethargy. Develops within 12-72 hours.
- Aflatoxin: Lethargy, vomiting, jaundice (yellow eyes/gums), reduced appetite. Damages liver.
Signs That Food Probably Isn't the Cause
Other common causes of similar symptoms:
- Getting into the trash or eating something else
- Ingesting a toxin (plants, cleaning products, human medications)
- Sudden diet change without proper transition
- Stress (new pet, move, household change)
- Parasites (worms, giardia)
- Viral infections (parvovirus in dogs, panleukopenia in cats)
- Bacterial infections
- Underlying medical conditions (pancreatitis, IBD, etc.)
If only one pet in a multi-pet household eating the same food is sick, the food is less likely to be the cause.
Step 1: Stop Feeding the Suspect Food
Don't continue feeding a food you suspect is contaminated, even if no recall has been announced. Switch to a bland diet (boiled chicken and rice for dogs, or a known-safe food for cats) for a few days while you investigate.
Step 2: Document Everything
Before doing anything else, record:
- Photos of the food — bag, can, contents, any visible abnormalities
- Product information — exact name, size, manufacturer, "best by" date, lot number, UPC code
- When you bought it — date and location
- Receipt if you have it
- Timeline of pet symptoms — what started when, what's gotten worse or better
- Photos of any visible symptoms (skin issues, eye discharge, etc.)
- Records of any vet visits and bloodwork
Save a sample of the food itself in a sealed container — both for testing and for refund purposes.
Step 3: Get Veterinary Care
If your pet is symptomatic, vet care is the priority. Tell your vet about your concerns regarding the food. They can:
- Run bloodwork to check for specific signs of food poisoning
- Test for specific toxins or pathogens
- Provide supportive care (IV fluids, anti-nausea, etc.)
- Document the case for potential reports
Don't wait if symptoms are severe — vomiting more than once or twice, bloody diarrhea, lethargy, or any neurological signs warrant immediate vet attention.
Step 4: Check Current Recalls
Verify whether the food is already recalled. Check:
- FDA pet food recall database
- Our recall hub
- Manufacturer's website
- Retailer notifications
If your specific product (matching the lot number and "best by" date) is on a recall list, you've confirmed the issue.
Step 5: Contact the Manufacturer
Whether or not the food is recalled, report your concerns to the manufacturer. They have a quality assurance department for exactly this purpose. Provide:
- Product details
- Timeline of symptoms
- Vet records if available
- Photos of the food
Quality manufacturers will request samples and lot information for investigation. They should also reimburse vet bills and replace the food. Some will deny or minimize — this is itself useful information about brand quality.
Step 6: Report to the FDA
This step is genuinely important and often skipped. The FDA tracks complaints to identify systemic issues. Reports of pet illness related to specific foods help trigger investigations.
How to report:
- Go to fda.gov and search "Report a Pet Food Complaint"
- Use the online portal (Safety Reporting Portal)
- Or call your nearest FDA Consumer Complaint Coordinator
Provide all the documentation you've gathered. Reports help the FDA identify whether your case is isolated or part of a pattern. Many recalls have been triggered by clusters of consumer complaints.
Step 7: Get Reimbursement
If the food caused illness, you're entitled to refunds:
- Food cost — from manufacturer or retailer
- Vet bills — from manufacturer (this often requires escalation)
- In severe cases — consult an attorney about further damages
Document everything you spend. Manufacturers typically reimburse documented expenses but may require multiple follow-ups.
What If You Can't Prove It Was the Food?
Even without definitive proof, you can:
- Stop feeding the suspect food
- Document your concerns for future reference
- Report to the FDA — they aggregate reports to find patterns
- Consider switching brands long-term
Definitive proof often requires lab testing of the food itself, which is expensive and rarely conclusive for individual consumers. The pattern of reports is what eventually triggers official investigations.
Frequently Asked Questions
Should I get the food tested by a private lab?
Usually not worth the cost. Private testing runs $200-500+ per sample and may not provide actionable results. The FDA does this when investigating suspected contamination.
What if the manufacturer denies any issue?
Document the denial and report to the FDA anyway. Brands that deny without investigation are often the same brands that get hit with bigger recalls later.
How long should I wait to see if it's the food?
If you stop feeding the suspect food and your pet recovers within a few days, the food may have been the cause. If symptoms persist beyond stopping the food, other causes are more likely.
The Bottom Line
If you suspect bad food, stop feeding it, document everything, get vet care, and report to both the manufacturer and the FDA. Your reports may protect other pets from the same issue. Brand recall history matters — check our recall hub when choosing your next food.
