On Farm A we were concerned with post-pasteurization of unsaleable milk being fed to calves. The source of contamination was hard to pin down. Back in April we brainstormed for all the places where bacteria could be coming from. One place we checked was the underside of the top of a milk transport tank - the tank was filled with pasteurized milk to feed the calves. BINGO! RLU reading of 6443! We agreed that this surface would continue to receive regular attention in the future. A matching test in June resulted in a RLU value of 39.
On Farm B we were concerned with inoculation of colostrum with bacteria during the collection process. Attention to teat preparation did not appear to decrease inoculation levels. Testing the collection bucket did not turn up contamination - RLU value of 29. I picked up the stainless steel lid and swabbed at the edge and under the gasket. RLU value of 2209! We agreed that in the future the gasket would be removed and cleaned as well as all surfaces of the stainless steel lid being scrubbed after each use.

Cleaning is not easy but it hammers inoculation.
Within 30 minutes after colostrum comes out of the cow our goal should be to either feed it to a calf or chill to 60°.
Chilling in ice-water works well especially for containers of 4 quarts or less.
Chilling with containers of ice directly in the colostrum works well at the ratio of one part ice to four parts of colostrum.
