Let me include this,

For nursing mothers, breastfeeding (feeding the baby with the mother's breast) is compulsory for your infant. In the first six month, exclusive breastfeeding is neccesary (feeding the baby only breastmilk), then you can continue brestfeeding with other foods till atleast 1 yr or maybe 2yrs... Also, there is also an age bracket tagged on each milk in the market, pls ensure you buy the one within your infant age range...

... For adults, i want to advise us to stay away from unpasteurized milk. Raw milk and its products (e.g. wara, nunu) as sold in sub-saharan africa is very unhygienic for our health. This is because Boiling alone as done on these milk products is not enough to eliminate the harmful bacteria in this milk. This raw and processed milk from cows, goats or cattles are unpasteurized milk and can carry dangerous bacteria such as Salmonella, E. coli, and Listeria, which are responsible for causing numerous foodborne illnesses.

Drink milk that is commercially sold and approved by appropriate organisations under ethical standards.
Drink only Pasteurized milk.
Kudos to @air-clinic for sharing this vital information
