What Does VSTA Stand For?

VSTA stands for Virus Serum Toxin Act

The Virus Serum Toxin Act (VSTA) is a federal law enacted to ensure the safety, efficacy, and purity of biological products, specifically those used in the prevention and treatment of diseases in animals. Established in 1913, the Act mandates rigorous standards for the testing and regulation of veterinary biologics, including vaccines and serum treatments, to protect animal health and prevent the spread of infectious diseases. VSTA is administered by the United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS), which oversees compliance and enforcement of these essential public health measures.
