Contagious mastitis is usually spread during milking. Milk from an infected quarter can be spread to the teat skin of other quarters and cows by dirty hands or gloves, teat cup liners, and cross flow of milk between teat cups. Hygienic practices at milking time help reduce this type of mastitis. Use good milking technique and a consistent routine.
