70% alcohol. Use a new swab or cotton ball for each teat. If you are treating all
teats, scrub the teat ends on the far side of the udder first, and then scrub teats on
the near side.
Treat teats on the near side first, and then treat those on the far side.
Use a mastitis treatment with a short infusion cannula or insert only the tip (3
millimetres) of a long cannula. Be careful the cannula does not touch anything until
it is inserted into the teat end.
Slowly infuse antibiotic preparation into the quarter.
Dip teats after treatment.
4.4.3 Feeding Medicated Feed
Producers that feed medicated feed must establish an SOP for feeding medicated feed.
The same Best Management Practices that apply to livestock treatments, such as
antibiotics, apply to medicated feeds. Medicated feeds must also be included on the
List of Medicines and Chemicals Used for Livestock (Record 9).
See Chapter 2 for more information on feeding medicated feed.
4.5 IDENTIFICATION OF TREATED CATTLE
Even when a treated animal's identification is recorded, it is essential in a valid HACCPbased
on-farm food safety program to also mark animals in the milking herd that have
been treated with animal health products that have a milk withdrawal. Proper marking
ensures that milking personnel know which animals have been treated and when milk
from each animal is safe to be placed in the bulk tank. This further reduces the chance
of shipping an animal or its milk before the appropriate withdrawal period; thereby,
reducing the risk that contaminated milk could become human food.
Dry cows must be marked if they have been treated with a product that has a milk
withdrawal and there is a risk that the dry cows can accidentally be mixed with or enter
the milking herd. For example, if there is only a gate separating lactating and dry
groups and the gate could accidentally be left open, treated dry cows must be marked.
It is also unacceptable to have dry cows housed on the milking line in a tie stall barn
without any indication that they are treated.
Some methods for marking treated animals are:
• Leg bands.
• Coloured tape (surveyor's tape, hockey tape, duct tape) around legs or tail.
• Paint or stock crayon markings on the animal's flank, rump, legs or udder.
• In tie-stall barns, a marker placed on the milk or vacuum line in stalls occupied by
treated animals plus the individual animals must be marked as being treated.
• In free-stall barns, creating a separate treated group (no risk of mixing with non-
