The milk from the dairy farm has not been kept for two hours at the longest, so it is better to deal with it as soon as possible. It is easy to cause bacterial growth if it is left for a long time.

From the point of view of pure consumption, freshly squeezed goat milk is drinkable. "But from a health point of view, it is best not to buy this kind of fresh milk." Because fresh milk has not been sterilized, it contains active pathogenic bacteria in livestock. If domestic animals are infected with brucellosis, tuberculosis, mastitis, foot-and-mouth disease, staphylococcus aureus infection and other diseases, milk is likely to contain pathogenic microorganisms of these diseases, which will cause human and animal diseases after drinking.

In addition, the prevalence of mastitis in dairy cows and sheep is as high as 70%, and dairy farmers generally use antibiotics such as penicillin and streptomycin. One week after drug withdrawal, there will still be antibiotic residues in cow and goat milk, and people who drink this milk are likely to have indirect allergic reactions to antibiotics.
