Failure to cover the whole teat of every cow at every milking or using incorrectly diluted teat sprays are the most common errors.
Bacteria in milk from infected quarters can contaminate the skin of many other teats during milking. After milking, these bacteria multiply on the teat skin and may enter the teat canal. Disinfecting the teat surface immediately after milking helps minimise the spread of bacteria.
