A 57 cow dairy herd, believed to be in excellent condition and producing well, was found to contain 30 tuberculous cattle after cervical skin testing employing bovine PPD tuberculin with the single intradermal comparative test. Testing was initiated after two cows from this herd were found at meat inspection to have tuberculosis. The reliability of bovine PPD tuberculin for testing as well as significant epidemiological, laboratory and meat inspection factors are presented.
