CDC, several states, and the U.S. Department of Agriculture's Animal and Plant Inspection Service (USDA) are investigating a multistate outbreak of multidrug-resistant Salmonella Heidelberg infections linked to contact with dairy calves. A total of 54 people have been reported from 15 states.

Salmonella

Clinicians should consider multidrug-resistant (MDR) Salmonella Heidelberg infection in the differential diagnosis of patients with exposure to cattle, farms, or farm workers and symptoms compatible with salmonellosis (e.g., diarrhea, fever, and abdominal cramps).

Guidance for clinicians whose patients have suspected or confirmed Salmonella Heidelberg infection related to this outbreak is available here.

If veterinarians recognize ill dairy calves with laboratory-confirmed Salmonella Heidelberg, they should report the illness to their State Animal Health Official. Guidance for veterinarians is available here.
