A recent study has underscored the potential threat posed by contaminated raw pet food to human health, shedding light on the prevalence of pathogens such as Salmonella and multidrug-resistant bacteria in these products. The research, conducted in Portugal and published in the journal Eurosurveillance, examined various meat and dog food samples from different suppliers between September 2019 and January 2020.
The investigation focused on raw meat-based diets (RMBD), a popular choice among pet owners, particularly since 2020, witnessing over 20 reports or recalls of pet food across the EU due to pathogen detection. Out of the 55 samples analyzed, only RMBD batches were found to be contaminated, with 10 out of 14 containing multidrug-resistant (MDR) E. coli and one harboring MDR Salmonella. Notably, one sample was positive for MDR Salmonella serotype 1,4,[5],12:i:-, suggesting a potential transmission route from raw pet food to humans.
Additionally, the study identified six Salmonella isolates, all monophasic Salmonella Typhimurium, in a single sample, while 59 E. coli isolates were found in raw-frozen food samples, albeit none were Shiga toxin-producing. Alarmingly, four colistin-resistant E. coli isolates carrying the mcr-1 gene were detected, highlighting the concerning emergence of resistance to last-line antibiotics.
The researchers emphasized the importance of heat treatment in pet food production to mitigate microbiological hazards, advocating for proactive measures involving the pet industry, food safety agencies, and pet owners to address these risks. They stressed the need to promote awareness among pet owners regarding the potential health hazards associated with RMBDs and the adoption of proper handling and feeding practices to minimize the risk of MDR bacterial infections in humans.
In a related study conducted in Slovenia, researchers explored pet owners’ risk perceptions and food preparation practices concerning raw meat-based diets. Findings revealed a lack of awareness among respondents regarding the fatal consequences of food poisoning, despite higher reported hygiene practices in the raw feeding group. The study highlighted the importance of raising awareness and providing guidance on safe handling practices for raw pet food.
Furthermore, concerns have been raised in England regarding the labeling and legality of pet food sold by home-based online suppliers. Following test purchases conducted by trading standards services in Somerset and Devon, it was found that many businesses failed to meet labeling requirements, with products incorrectly labeled and claims unsubstantiated. Authorities stressed the necessity for businesses to adhere to strict regulations to ensure transparency and consumer safety in the pet food industry.
As the demand for raw pet food continues to rise, these findings underscore the critical need for concerted efforts to address food safety concerns and ensure the well-being of both pets and their owners.
