TCM arises where chlorine or chlorine containing detergents come in contact with milk or other organic matter.  The chlorine will react with the organic compound and TCM’s are formed, this in itself is not a problem provided the milking machine or the bulk tank are rinsed properly with clean water.  On some farms inadequate rinsing takes place, 14 litres of fresh rinse water is required per milk unit to adequately rinse all traces of detergent from a milking machine. 

Testing of farm samples is being carried out in conjunction with Moorepark, farms where high levels of TCM are detected will be advised and follow-up sampling carried out to eliminate the problem, your co-operation in resolving this matter is essential.
