I am in the SA Navy and we have our own Chefs and dinning halls which receives Milk from Darling Dairy products. The Milk has an expiry date printed on the side of the plastic bottle but it is off before the expiry date, eg. 31/12/2021 is printed but that morning the milk is already thick and you coffee has thick chunks of milk drifting inside it.
