How to know your milk has gone bad

By Carolyne B. Atangaza

Nutritionists recommend regular drinking of milk because of its richness in nutrients. However, drinking it when spoilt can result in a variety of problems including food poisoning and stomach aches, nausea, vomiting or diarrhoea.
According to Purity Wako, a nutritionist and dietician, there are different tests you can do to ascertain milk freshness.

Smell the milk: Spoiled milk has a foul sour smell. Check the consistency, pure milk is a thin and smooth liquid. If the milk separates itself into inconsistent lumps that is a sure sign it has gone bad.

Inspect the colour: Fresh cow’s milk is usually a cream colour. After processing, such as pasteurization, and homogenization, which blends the milk and cream together and heated to kill any bacteria, it does take on a more whiter appearance.

Boil a sample: It is very essential to check and verify the “best before” date written at the back of the carton or packet, before consumption. Scientists recommend using milk before three days of its ‘best before’ date. If it is even slightly yellow or pale white; there is a strong chance that your milk is not safe to consume.
To inspect the colour better, you can pour the milk in a transparent glass and observe it against the light. If the colour is anything but white, your milk has gone bad.

Preservation
To preserve your milk, make sure, if it is sitting out, it is only at the recommended 39 degree F (4 degree C). If it is not in use, do keep the milk back into the refrigerator to preserve it for long.
