Blackspot (TCCD 4.8) is the manifestation of a secondary infection of a teat end lesion by the anaerobe Fusiformis necrophorum. The primary lesion is colonized following poor hygiene. The resulting scab is pigmented black by the bacteria. The teat orifice may become blocked, leading to incomplete and very slow milking.
If more than 2 –3% of teats are affected, hygiene should be improved and milking machine function should be thoroughly checked because blackspot is often associated with short teatcup liners, failure of pulsation, excessive vacuum or over milking.
The management of the winter housing also has a significant impact with heavy soiling of free stalls and straw packs increasing the regularity of identification of blackspot.

| Medium | Management of blackspot in a herd involves: • treating the lesions with hydrogen peroxide or iodine; • using teat disinfection to minimize bacterial infection of lesions; and • checking the milking machine function |
