BackgroundBiologically appropriate raw food (BARF) diet is becoming more and more popular among pet owners in Europe. However, there are documented microbiological risks associated with raw feeding, and this study aimed to determine the presence of human pathogens in commercially frozen BARF products sold in Italy.MethodsSalmonella species, Escherichia coli O157:H7, Listeria monocytogenes and Campylobacter species were identified. The general microbiological quality of BARF products and hygiene were also evaluated. Sample size was limited and therefore the study may not be representative of a larger sample.ResultsNone of the tested samples showed total bacterial count (TBC) higher than the limit set to consider a sample unacceptable. However, 14 out of 21 samples showed TBC higher than the limit set to consider a sample marginally acceptable. A high percentage of samples were contaminated by the aforementioned pathogens, highlighting the need for pet owners to be aware of the risks of this feeding strategy both to themselves and to their pets.ConclusionsConsidering that BARF diet meals can be prepared at home using the hands, as well as tools and spaces that could be shared, guidelines on safer handling of these pet food products should be recommended by veterinarians and nutritionists.

“…monocytogenes is a pathogen transmitted by food. Raw meat (Yücel, Citak, & Onder, 2005), dairy foods, non pasteurised milk (Carminati, Perrone, Giraffa, Neviani, & Mucchetti, 2004;Lo Nostro, Tiscione, Galassi, Donato, & Ademollo, 1995;Pintado, Oliveira, Pampulha, & Ferriera, 2005;Tiscione, Lo Nostro, Donato, Galassi, & Ademollo, 1994) and soft or semi-soft cheeses are major sources of outbreaks of listeriosis. And even vegetables (Beuchat, 1996;Harvey & Gilmour, 1993) and fish, such as smoked salmon (Rørvik, Aase, Alvestad, & Caugant, 2000), may act as vehicles of transmission of this pathogen.…”

“…The ability of L. monocytogenes to grow at chilling temperature and to tolerate salt and low pH, make this pathogen particularly troubles to the food industry (Carminati et al, 2004). The L. monocytogenes is widely distributed in the environment and has been isolated from a variety of sources including water, sludge, soil, plants, vegetation, food, food processing plants and infected humans and animals (Dhama et al, 2013).…”

Listeria monocytogenes is responsible for causing the serious infectious disease listeriorosis which occurs due to food contaminated with Listeria. The study employed herein concerned with the isolation and identification of L. monocytogenes from foodstuffs and water. Hundred different food stuffs samples (milk, cheese and meat) and 50 fresh water samples were surveyed for presence of L. monocytogenes. These samples were inoculated into two enrichment media and cultivated on Oxford agar. Presumptively positive isolates were determined by morphology of colonies, gram stain, catalase test, haemolysis on sheep blood agar and motility test. The isolates were further identified to species level by 10300 API Listeria strips, PCR was done for all specimens to evaluate its accuracy. Out of 100 foodstuffs samples, 15 samples were showed positive results for Listria species. Out of 50 fresh water samples, 5 samples were showed positive results. Antibiotic susceptibility was done for all identified strains. All isolates were sensitive to penicillin G, ampicillin, tetracycline, amikacin and erythromycin.
