Abstract

The Veterinary Laboratory Investigation and Response Network (Vet-LIRN), in collaboration with the Food Emergency Response Network (FERN) and its Microbiology Cooperative Agreement Program (MCAP) laboratories, conducted a study to evaluate the prevalence of selected microbial organisms in various types of pet foods. The goal of this blinded study was to help the Center for Veterinary Medicine prioritize potential future pet food-testing efforts. The study also increased the FERN laboratories' screening capabilities for foodborne pathogens in animal feed matrices, since such pathogens may also be a significant health risk to consumers who come into contact with pet foods. Six U.S. Food and Drug Administration FERN MCAP laboratories analyzed approximately 1056 samples over 2 years. Laboratories tested for Salmonella, Listeria, Escherichia coli O157:H7 enterohemorrhagic E. coli, and Shiga toxin-producing strains of E. coli (STEC). Dry and semimoist dog and cat foods purchased from local stores were tested during Phase 1. Raw dog and cat foods, exotic animal feed, and jerky-type treats purchased through the Internet were tested in Phase 2. Of the 480 dry and semimoist samples, only 2 tested positive: 1 for Salmonella and 1 for Listeria greyii. However, of the 576 samples analyzed during Phase 2, 66 samples were positive for Listeria (32 of those were Listeria monocytogenes) and 15 samples positive for Salmonella. These pathogens were isolated from raw foods and jerky-type treats, not the exotic animal dry feeds. This study showed that raw pet foods may harbor food safety pathogens, such as Listeria monocytogenes and Salmonella. Consumers should handle these products carefully, being mindful of the potential risks to human and animal health.

Archives Highlights:
Comparison of complications and outcome following unilateral, staged bilateral, and single-stage bilateral ventral bulla osteotomy in cats.
Overall, 68.2% (n = 197) of the 289 procedures were associated with Horner syndrome (19.4% permanently), 30.1% (87) with head tilt (22.1% permanently), 13.5% (39) with facial nerve paralysis (8.0% permanently), and 6.2% (18) with local disease recurrence.
Restraint of dogs in vehicles in the US, UK and Australia.
A little over half of respondents restrained their dog in the US (55%) compared to 67% in Australia and 72% in the UK. The most common method of restraint in the US and UK was a cage/crate in the cargo area in the back of the vehicle; in Australia it was a harness and tether attached to a seat buckle.
Collection of cerebrospinal fluid into EDTA versus plain tubes does not affect the standard analysis in dogs.
The total nucleated cell count did not differ significantly between EDTA and plain tube samples. There were no significant differences in the differential cell counts between the two tubes when evaluating polymorphonuclear cells, lymphocytes, and monocytes/macrophages. Also, there was no significant difference in the preservation of cell morphology when evaluating cytological preparations from EDTA stabilised and plain tube samples.
Cross-sectional survey of pet ownership, veterinary service utilisation, and pet-related expenditures in New Zealand.
The median yearly veterinary expenditure was $200-499 by dog owners, $100-199 by cat owners, and less than $100 by horse, bird, rabbit, and fish owners. The best source of information for pet-related issues was considered to be veterinarians by 724/1,001 (72.3%) owners, and the internet by 509/1,001 (50.8%) owners.
Canine Brucellosis: Old Foe and Reemerging Scourge.
This review summarizes the epidemiology, clinical signs, and advances in diagnosis and management of Brucella canis. Canine brucellosis prevention, owner education, and possible therapies for the future are also discussed.
