The Pennsylvania Department of Agriculture issued a report Friday after an adult beef cow that attacked her owner tested positive for rabies.

The cow was euthanized and showed other abnormal behaviors such as vocalizing abnormally and attacking her herd mates. 

The department of agriculture said two people were exposed and are receiving post-exposure treatment.

Additionally, 19 other beef animals could have been exposed to the cow and will be vaccinated and quarantined for 120 days.

According to the department of agriculture report, Pennsylvania law requires all dogs and cats three months of age and older to be vaccinated against rabies.

Failure to comply with the law may result in a fine of up to $300. 

Livestock owners are encouraged to consult their veterinarians and include a rabies vaccine in their animal health protocol.
