C. Topical Antiseptics and Wound Dressings

Topical antiseptics and wound dressings (unless intended for direct
injection into the teat) are exempt from the labeling requirements.
Topically applied drugs that are not antiseptics or wound dressings must
comply with all labeling, use, and storage requirements.

This category includes creams, ointments, sprays, wound dressings, some
foot products, teat dips, tincture of iodine and others. The following is a list
of commonly used topical antiseptics and wound dressings that are
exempt from the labeling requirements. They should only be used topically
and must be stored so as not to contaminate the milk or product
contact surfaces.

 Iodine  Blue Coat
 Alcohol  Kopertox
 Hydrogen peroxide  Granulex Spray
 Teat dips/Udder  Trypzyme Aerosol
washes  Chlorhexidine** solutions,
 Chlorine bleach ointments, salves, and
 Formalin (for cattle creams for topical use only

D. FOOTBATHS:

Medicated foot baths and sprays used to treat and control cattle foot rot
and heal warts. Veterinarians prescribe and dairy producers routinely use
medicated foot baths or sprays to control hoof disorders in dairy cattle.
These baths and sprays often contain antibiotics such as oxytetracycline.
To comply with the PMO these types of baths and sprays must be
operated in a manner that will not contaminate the milk or surface of the
milk product contact equipment. The use of antibiotics for foot baths/sprays
constitutes extra label use. Veterinarians should comply with the labeling
requirements for extra label use of drugs under PMO item 15r.

To prevent milk contamination, foot baths generally should be located on
the exit side of the milking area (walk-through after milking). Spraying
medication onto the cattle’s hooves should not occur in the milking area
during milking time.
