Bureau of Animal Health and Diagnostic Services (BAHDS)

The Bureau of Animal Health and Diagnostic Services (BAHDS) is responsible for controlling and eradicating diseases in livestock and poultry. This mission is critical since these diseases have the potential to impact human health and cause significant economic loss to farmers and the commonwealth. In addition, BAHDS administers regulatory programs for animal health certification, containment of diseased animals and elimination of disease agents.

Pennsylvania is also home to a tri-partite animal health laboratory system called the Pennsylvania Animal Diagnostic Laboratory System, or PADLS. PADLS connects the Pennsylvania Veterinary Laboratory (PVL) in Harrisburg, Penn State University's Animal Diagnostic Laboratory (ADL) and the University of Pennsylvania School of Veterinary Medicine's New Bolton Center to provide laboratory testing, field-based monitoring and producer outreach, all with a focus on protecting our citizens, our food supply and our animal agriculture industry.

With millions of livestock and poultry in Pennsylvania, BAHDS has a presence throughout the state with Veterinary Medical Field Officers and Domestic Animal Health Inspectors headquartered across seven regions. These staff members work closely with the farming and non-farming public on issues ranging from suspected rabies cases to farm-based animal health questions.

The work performed everyday by BAHDS is essential to protecting U.S. livestock and poultry industries from foreign animal diseases, which, in turn, protects our food supply and our citizens. Maintaining a healthy animal agriculture industry is also a key step to ensuring Pennsylvania's trade status with other states and nations is not negatively impacted by an outbreak within our borders.

Our mission is just one facet of the Pennsylvania Department of Agriculture's mandate to ensure the safety, accessibility and prosperity of our commonwealth's agriculture sector, and we take it very seriously.
