Bovine Salmonella Serotypes Isolated in Ohio in 2020

Dominika Jurkovic, Ph.D., Laboratory Scientist 3, Bacteriology


In 2020, the Bacteriology Section isolated 74 Salmonella sp. from bovine samples submitted to ADDL. Samples submitted included feces (65%), lung (18%), placenta (7%), pooled tissue (5%), brain (3%), joint (1%), and small intestine (1%). Salmonellas isolated at ADDL are serotyped by the National Veterinary Services Laboratory, or by the Ohio Department of Health Laboratory when rushed serotyping is requested by a veterinarian. When analyzing the serotyping data, duplicate animals are removed from analysis. For example, an accession with 3 animals may all have the same serotype, so that only counts as one serotype for this analysis. The chart below summarizes the serotypes isolated from bovine samples in 2020 (n=44). Salmonella Cerro, Dublin, and Montevideo were the top 3 serotypes identified from bovine samples in the past year.


Certain Lots of Sportmix Pet Food Recalled for Potentially Fatal Levels of Aflatoxin

Jing Cui, DVM, MS, Bacteriology Section Head


The U.S. FDA is investigating and alerting pet owners and veterinary professionals about certain Sportmix pet food products manufactured by Midwestern Pet Foods, Inc. that may contain potentially fatal levels of aflatoxins.

On January 11, 2021, Midwestern Pet Foods expanded the recall to include additional products that contain corn and were made in their Oklahoma manufacturing plant. As of January 21, 2021, FDA is aware of more than 110 pets that have died and more than 210 pets that are sick after eating certain pet food manufactured by Midwestern Pet Foods. This is an ongoing investigation. Case counts and the scope of this recall may expand as new information becomes available.

Aflatoxins are toxins produced by the mold Aspergillus flavus, which can grow on corn and other grains used as ingredients in pet food. At high levels, aflatoxins can cause illness and death in pets. Pets experiencing aflatoxin poisoning may have symptoms such as sluggishness, loss of appetite, vomiting, jaundice (yellowish tint to the eyes or gums due to liver damage), and/or diarrhea. In severe cases, this toxicity can be fatal. In some cases, pets may suffer liver damage but not show any symptoms.

Pet owners should stop feeding their pets the recalled products listed below and consult their veterinarian, especially if the pet is showing signs of illness. The pet owner should remove the food and make sure no other animals have access to the recalled product.

FDA is asking veterinarians who suspect aflatoxin poisoning in their patients to report the cases through the Safety Reporting Portal or by calling their local FDA Consumer Complaint Coordinators. Pet owners can also report suspected cases to the FDA. For the most recent information on the subject visit:
