Raw pet food warning draws pushback over risk framing: full analysis

A new public disagreement over pet food safety messaging is putting raw diets back in the spotlight. In an April 27 article, Truth about Pet Food’s Susan Thixton said the Center for Science in the Public Interest “wasn’t in the interest of the pet owning public” after CSPI published consumer guidance on April 23 warning that raw pet food “poses the greatest risk” for harmful bacterial contamination.

The immediate trigger was CSPI’s article, “Can pet food make you sick? Here’s how to stay safe,” which framed contaminated pet food as a human as well as animal health issue. CSPI cited FDA and CDC material showing that pets can shed pathogens after eating contaminated food and emphasized handwashing, surface disinfection, and keeping pet food separate from human food preparation areas. The article singled out raw diets because FDA’s Center for Veterinary Medicine found higher rates of Salmonella and Listeria contamination in raw samples than in the other pet food categories it tested.

That FDA study remains one of the key federal references in the raw-feeding debate. According to FDA, the agency screened more than 1,000 pet food samples from October 2010 through July 2012. Raw pet food was added in the second year, and among 196 commercially available raw dog and cat food samples, 15 were positive for Salmonella and 32 for Listeria monocytogenes. By comparison, FDA reported no Salmonella positives in dry dog food, one in dry cat food, and none in the semi-moist, jerky-type, or dry exotic pet food samples included in the study; canned foods were not tested. FDA says those findings support concern about raw diets as a public health risk for both pets and the people handling the food. (fda.gov)

Thixton’s rebuttal does not dispute that raw products can carry pathogens. Instead, it argues that CSPI’s framing could leave pet parents too complacent about kibble and other processed foods. Her article points to major dry-pet-food recalls, including the 2012 Diamond Pet Foods Salmonella outbreak and the 2023 Mid America Pet Food recall. CDC says the 2023 outbreak linked to dry dog food sickened seven people, and FDA’s November 2024 warning letter to Mid America said the inspection followed a multistate Salmonella Kiambu outbreak investigation tied to the company’s 2023 Class I recalls. Thixton also cites CDC’s 2017 to 2019 Salmonella Reading outbreak linked broadly to turkey, noting that only four interviewed patients reported illness after pets in their home ate raw ground turkey pet food.

The federal outbreak record is more nuanced than either side’s headline framing. CDC’s MMWR report on the 2017 to 2019 turkey outbreak found 356 cases across 42 states and Washington, DC, with the outbreak strain isolated from raw turkey products, raw turkey pet food, and live turkeys. Among 198 interviewed patients, 123 reported preparing or eating raw turkey products, while four became sick after pets in their home ate raw ground turkey pet food; no single brand or source was identified. Separately, FDA documented a 2018 investigation in which two children in one Minnesota household were infected with the same Salmonella Reading strain found in Raws for Paws ground turkey pet food fed to the family dog.

Industry and professional guidance has generally been more aligned with CSPI than with Thixton on the core question of raw-food risk. AVMA says contamination can occur in cooked or processed products too, but notes that raw products are a particular concern. CDC likewise advises against feeding raw pet food because raw meat and other raw proteins can contain pathogens such as Salmonella and Listeria. That doesn’t erase the reality that dry foods can also be implicated in human outbreaks, but it does reinforce the current mainstream veterinary position that raw diets require especially careful counseling.

Why it matters: For veterinary teams, this episode is a reminder that pet parents are encountering competing narratives from advocacy groups, regulators, and independent pet food commentators. The practical takeaway is to separate two different questions in client communication: relative contamination risk by product type, and absolute outbreak burden across the market. Raw diets continue to stand out in FDA contamination testing, while processed diets have also caused large recalls and documented human illness. Clinics that explain both points clearly, then focus on safe handling, household risk factors, and nutrition adequacy, will be better positioned to give balanced advice. (fda.gov)

What to watch: The next signal will be whether CSPI responds publicly to Thixton’s criticism, and whether veterinary groups update client-facing education as food safety concerns increasingly intersect with zoonotic disease messaging, including for households with children, older adults, pregnant people, or immunocompromised family members.
