Milk is tested to see if it has microbes by sending a sample to a lab. There are a number of local health departments that send out people to check up on this. They return with small samples that are streaked on plates and put into an incubator and then checked in 1-2 days to see what grew. Since milk is produced from the udders of cows, there will be small numbers of microbes.

How a lactometer can be used to test the purity of milk?

A lactometer is a simple device used to measure the density of milk, which is correlated with its fat content. By placing the lactometer in a sample of milk, the reading can indicate whether the milk has been diluted with water or has had fat removed. A lower reading suggests the presence of added water, while a higher reading indicates the removal of fat.
