The USDA intends to award a sole source firm-fixed-price contract to Covetrus North America LLC for the supply of Negasunt Powder and Tanidil, which are solely manufactured by Elanco Animal Health. These products are used for the prevention and treatment of NWS myiasis in livestock and certain wildlife, and will be distributed through APHIS via the National Veterinary Stockpile (NVS) in coordination with state and tribal agencies. The contract is under NAICS code 325414, and the government is conducting market research to identify potential alternate sources. If no other sources are identified, the award will proceed as a sole source. No budget amounts, submission timelines, or performance location are specified in this notice.
