Mycobacterium avium subsp. paratuberculosis (Mpt) is the etiologic agent of Johne’s disease, a chronic intestinal disease in cattle that threatens the economic viability of dairy farming. Diagnostic culture is typically unrewarding until several years after infection when clinical signs can be observed. This leads to widespread infection within the herd. Difficulty in culturing Mpt may be a result of oxidative damage due to the increased metabolic rate when dormant organisms are recovered in a nutrient rich medium. In order to improve recovery it is believed that some organisms secrete a growth factor in times of environmental stress which enables them …

Chemical Sterilisers In The Dairy Industry, D N. Tulloch, N. Ingleton
Journal of the Department of Agriculture, Western Australia, Series 4

The sterilisers could also affect tests for antibiotic residues in milk. The responsibility of seeing that chemical sterilisers do not enter the milk belongs to the dairy farmers.
They should follow the manufacturers' recommendations and use the chemicals with care.
