The cow may have mastitis. Its teats may not have been sterilised first. The cups on the milking machine may be contaminated. If it is being hand-milked, the person's hands may be contaminated. The vessels the milk goes in to during milking may also be contaminated.
milk becomes contaminated when the people doing the process get sick of waiting for the toilet and decide to take a crap in the milk.
Milk can get contaminated in these ways: Germs from an animal’s skin can get in milk Germs in the environment (including the barn and milking equipment) can get in milk The dairy animal’s udder can be infected (mastitis) The dairy animal can have a disease (for example, bovine tuberculosis) Insects, rodents, and other small animals can get in milk Conditions in the milk processing plant can be unsanitary Cross-contamination from dairy workers can happen—for example, through contact with dirty clothing or boots
There are four teats to a cow's udder. They are used for suckling a calf. In milk production, hand milking may be used, but large scale operations use milking machines (and reserve hand milking for sick cows, so that the contaminated milk does not go into the holding tank).
The milking machine has evolved from a simple can that would milk a single cow to a much more complicated device. The milking machines of today can milk many cows at once, and all of the milk is transferred directly into a large tank that chills the milk until it is picked up by the dairy truck.
Dairy reproduction is the breeding and milking process of dairy cattle for the purpose of milk production.
Milking machines revolutionized dairy farming practices by automating the milking process, increasing efficiency, and reducing the manual labor required. Before milking machines, farmers had to milk cows by hand, which was time-consuming and physically demanding. The introduction of milking machines allowed for faster, more consistent milking, leading to increased productivity on dairy farms.
Drinking milk is possible due to the process of pasteurization. This process first took place in the United States in the mid 1800s.

This will depend on how much milk she is still producing once she comes home. If her udder is still looking full you may be able to start milking her again. Keep in mind that she might have mastitis, treat it as you normally, and begin milking her. It is probably a good idea to see if she does have mastitis either way, if she does treat it and dry her off if she is not able to milk. A month should not be too harmful to her, if she was producing milk before hand, however, anywhere longer than that you might not be able to begin the milking process.
