Answers Pet Food FDA Warning: Salmonella & Listeria Contamination — What Dog Owners Should Do

If you feed your dog a raw diet, you may have seen the FDA’s warning about Answers Pet Food circulating in news feeds and recall trackers. The situation is ongoing, and the details matter — which lots are affected, what the bacteria can do to your dog and to you, and exactly what to do if you have one of these products in your freezer.

This guide explains the FDA warning in plain terms, based on the agency’s own advisory and warning letter. The goal is practical: help you check whether your dog’s food is affected, recognize the symptoms of Salmonella and Listeria infection, and handle raw pet food safely while the investigation continues.

If your dog has eaten an affected product and is vomiting, has diarrhea, fever, or lethargy, call your veterinarian now. Humans handling contaminated raw food can also get sick — wash hands and surfaces thoroughly. For poison and food-safety questions, the ASPCA Animal Poison Control Center (888-426-4435) is available 24/7, and you can search related hazards in our Pet Toxin Lookup tool.

What Happened: The FDA Warning, In Plain Terms

Lystn LLC, doing business as Answers Pet Food, received a warning letter from the U.S. Food and Drug Administration after inspections and testing confirmed contamination with Salmonella and Listeria monocytogenes in multiple raw dog food formulas. The FDA classified the affected products as adulterated and potentially unsafe.

Two dates anchor the timeline:

• February 14, 2025 — the FDA’s announcement date for the advisory.
• June 18, 2025 — the date of the FDA’s formal warning letter to Lystn LLC.

It is important to understand what this is and is not. The FDA issued an advisory and a warning letter — a formal “do not feed this product” notice backed by testing. It is an enforcement action and a public-health warning, even though it is structured as an advisory rather than a voluntary company recall. The status is currently marked ongoing, which is why it continues to appear in recall trackers. Petful, which aggregates FDA and AVMA notices, lists this advisory and cross-checks it against the FDA notice.

Which Products Are Affected

Three raw dog food formulas are named in the FDA warning. All are raw, refrigerated or frozen products sold nationwide:

• Answers Raw Beef Detailed Formula for Dogs — affected best-by date: May 06, 2026
• Answers Raw Beef Straight Formula for Dogs — affected best-by date: Jan 31, 2026
• Answers Straight Chicken Formula for Dogs — affected best-by dates: Jan 02, 2026 and Mar 11, 2026

These are lot-level identifiers tied to best-by dates, not a blanket recall of the entire brand. If you feed Answers, the action step is specific: check the best-by date on your package against the dates above.

Good to know: “Best-by” dates are the identifying marker for the affected lots here. The FDA warning letter lists the dates above as the lots testing positive for contamination. If your package’s best-by date does not match one of these, it is not in the named lot — but given the ongoing status and raw-food contamination risk, you may still want to read the safety guidance below.

Why Salmonella and Listeria Are a Serious Concern

Both bacteria are dangerous — and unlike many pet-food hazards, they are also a direct risk to the humans handling the food.

Salmonella

Salmonella is one of the most common causes of bacterial foodborne illness. In dogs, it can cause:

• Diarrhea (which may be bloody)
• Vomiting and loss of appetite
• Fever and lethargy
• Abdominal pain

A particularly tricky feature of Salmonella is that infected but healthy-looking dogs can still shed the bacteria in their feces, spreading it to other animals and to people in the household. This is why raw-food contamination is a family-health issue, not just a pet-health issue.

Listeria monocytogenes

Listeria is less common than Salmonella but can be more severe, especially in vulnerable individuals. In dogs, symptoms can include:

• Diarrhea and vomiting
• Fever
• Lethargy and reduced appetite
• In serious cases, neurological signs

For humans — especially pregnant women, newborns, older adults, and immunocompromised people — Listeria can cause serious, sometimes life-threatening illness. This is why public-health agencies treat Listeria contamination in any food, pet or human, as a high-priority concern.

Symptoms to Watch For

If your dog has eaten an affected lot, monitor for these signs:

• Diarrhea — especially if frequent, bloody, or lasting more than a day
• Vomiting — repeated or with blood
• Fever — a rectal temperature above 102.5°F (39.2°C) is above normal for dogs
• Lethargy — unusual tiredness, reluctance to move or eat
• Reduced appetite — refusing meals or eating much less than usual
• Abdominal pain — a hunched posture or guarding the belly

In people handling the food, watch for nausea, vomiting, diarrhea, abdominal cramps, fever, muscle aches, and fatigue. If anyone in your household becomes ill after handling affected raw pet food, contact a physician and mention the exposure.

When to call the vet: Any combination of vomiting, diarrhea, and lethargy warrants a vet call — particularly in puppies, seniors, or dogs with weakened immune systems, who are more vulnerable to dehydration and severe infection. Do not wait for symptoms to escalate.

What to Do If You Have an Affected Product

The FDA’s guidance for affected products is straightforward:

1. Stop feeding the product immediately. Do not continue the current bag even if your dog seems fine — shedding of bacteria can continue without symptoms.
2. Check the best-by date against the affected lots listed above. If it matches, the product is covered by the warning.
3. Dispose of the food safely. Double-bag it and put it in a sealed trash container so other animals cannot reach it. Wash your hands thoroughly afterward.
4. Clean everything it touched. Wash bowls, utensils, storage containers, and any surfaces with hot soapy water. Sanitize the area. This protects both your dog and the people in your home.
5. Contact the brand if you have questions. Answers Pet Food lists its contact information as answerspetfood.com and 717-362-3800 (Monday–Friday, 9 AM – 5 PM ET).
6. Call your veterinarian if your dog has eaten the affected lot, even before symptoms appear — your vet can advise on monitoring and whether a checkup is warranted.

The Bigger Picture: Raw Pet Food and Bacterial Risk

This FDA warning is part of a larger, well-documented pattern. Raw pet food — whether frozen, freeze-dried, or refrigerated — consistently shows higher rates of pathogen contamination than cooked pet food, because cooking is the step that kills Salmonella, Listeria, and E. coli. Multiple major raw-food brands have faced FDA warnings or recalls in recent years over the same bacteria.

This does not mean every raw diet is automatically dangerous, but it does mean raw feeding carries a real, recurring contamination risk that owners should weigh seriously. Key points the veterinary and public-health consensus supports:

• Cooking kills these pathogens. This is why commercially cooked diets and properly cooked home-prepared food have far lower contamination rates.
• Raw food can sicken healthy-looking pets and their humans. The shedding risk means a seemingly fine dog can expose a child, an elderly family member, or an immunocompromised person.
• Hygiene matters enormously with raw food. Hand-washing, dedicated utensils, and surface sanitizing are not optional — they are the barrier that prevents human illness.

If you are weighing whether a raw diet is right for your pet, the contamination risk is one of the central factors to consider alongside nutritional balance. We cover that full decision in our guide to raw diet safety (coming soon). For now, the FDA’s position is clear: treat the affected Answers lots as adulterated, and handle all raw pet food with care.

How to Stay Ahead of Pet Food Recalls

Recalls and FDA advisories happen more often than most owners realize, and acting quickly matters. A few practical habits:

• Bookmark a recall tracker. The Petful recall tracker aggregates FDA and AVMA notices and is updated daily. The FDA’s own Recalls, Market Withdrawals & Safety Alerts page is the primary source.
• Keep the product packaging — or at least photograph the best-by date, lot code, and brand. You cannot check an affected lot without this information.
• Sign up for recall alerts. Free email alerts from Petful or the FDA deliver notices the same day they are issued.
• Know the symptom pattern. Sudden gastrointestinal illness in a pet that recently changed food is a signal to check whether that food has been recalled.

Frequently Asked Questions

The Bottom Line

The FDA’s ongoing warning about Answers Pet Food is a real, documented food-safety event: specific raw dog food lots tested positive for Salmonella and Listeria, the agency told the public not to feed them, and the status remains active. If you feed Answers, check your best-by dates against the affected lots and act on the guidance above. More broadly, this is a reminder that raw pet food carries a recurring contamination risk that affects both pets and the people who handle their food — worth weighing carefully in any raw-feeding decision.
