Bovine viral diarrhea virus (BVDV) has been found to survive longer in water and mucus, compared to other materials like soil and metal. If a persistently infected animal is present in your herd, mucus harboring the virus could transmit BVDV to other animals that share the same waterer.

Clean those water tanks“Cleaning water tanks is very important for many reasons, including food safety, animal performance and general upkeep of facilities,” says Dan Thomson, veterinary researcher at Kansas State University.

Use of a very dilute bleach solution is one way to disinfect water tanks to help prevent the spread of BVDV. Talk to your veterinarian about other safe options.
