Due to the past outbreaks of TB in California there is increased concern on the exposure of animals especially during movement like going to fairs and shows. This is a bio-security risk management concern and can have devastating effects on cattle producers in our county.
The Merced Fair had required TB testing for the dairy Replacement Heifer program animals and recommends other cattle over 6 months be tested before the show.
Testing can be done by a veterinarian, and is a 4 day process. Day one an injection is made at the tail head, four (4) days later it is read for a positive or negative reading for TB.
Contact your local vet for more information on the test.
