Under Australian conditions, virtually all mastitis infections enter the udder through the teat end via the teat canal. 

The teat canal is a wonderful structure that is constantly working hard to prevent bacteria from entering the udder.  If it is either overwhelmed by large numbers of bacteria, or it is damaged and can’t do its job properly, then the cow is at a much greater risk of becoming infected.

Routine post-milking teat disinfection has been, and still is, the single most effective component of hygienic milking programs used in Australia.
