Background Dried non‐heat‐treated meat treats, such as ears, skin and tails, are popular supplementary dog foods. Previous studies have demonstrated Salmonella spp. contamination on treats, particularly in pig ears and chicken products. This small, exploratory, cross‐sectional study investigated Salmonella spp. presence in dried treats available in the UK. Methods A selection of dried treats from local pet shops and online retailers underwent bacterial culture for Salmonella spp. and subsequent antimicrobial susceptibility testing, with Salmonella serotype determined by whole genome sequencing. Results Eighty‐four samples were tested, with 16% being Salmonella spp. positive. Five Salmonella serotypes were identified, each associated with specific treat types. An antimicrobial‐resistant phenotype was identified in 39% of isolates. All serotypes identified are known to cause human infection. Limitations This study was limited by a small sample size and limited number of retail sources. Conclusion Salmonella spp. of public health concern were present in some dried dog treats in this study. Dog owners, pet food retailers and veterinary professionals should be aware of the potential zoonotic disease risk associated with these treats, and appropriate hygiene measures, including thorough hand washing, should be utilised if they are fed.

PICO question In cats infected with Tritrichomonas foetus, does treatment with oral ronidazole compared to an alternative antiprotozoal treatment or placebo result in successful resolution of clinical signs and eradication of disease? Clinical bottom line Ronidazole use appears to be efficacious in eradicating infection with Tritrichomonas foetus and resolving diarrhoea associated with infection. A dose range of 30–50 mg/kg 12–24 hourly has been suggested, with evidence suggesting that a dose of 30 mg/kg 24 hourly for 14 days may be effective. However, some cats may require higher doses and some may not respond to treatment, and relapse may occur during a protracted period following completion of the treatment course. Neurological side effects appear to be uncommon but may occur with doses of 30 mg/kg and above. A total of six studies are reviewed: Three randomised, controlled studies, one cohort study and two case series (one retrospective). Findings indicate efficacy of ronidazole treatment in eradicating infection and resolving diarrhoea, however many studies involved small sample sizes and limited follow-up. Therefore, evidence to support the use of ronidazole in Tritrichomonas foetus infected cats remains relatively limited.
