Milk borne diseases

Hey there kiddo! Do you know what milk is? It's a liquid that some animals, like cows, make to feed their babies. Humans also drink milk because it has some healthy things in it, like calcium and protein. But sometimes, milk can make us sick, because there are tiny living things in it called germs.

These germs can get into the milk when the cows are being milked or when the milk is being processed. If we drink milk that has germs in it, we might get what is called a milk-borne disease. This means that the germs make us feel sick, with symptoms like stomach pain, diarrhea, and vomiting. Milk-borne diseases can be especially dangerous for little kids and older people.

Some common milk-borne diseases include:

- Salmonella: This is a type of germ that can get into the milk from chickens or from other animals that live on the farm. It can cause diarrhea, fever, and stomach pain.

- E. coli: This is another germ that can get into the milk from cows. It can also cause diarrhea, fever, and stomach pain.

- Listeria: This is a germ that can grow in milk even if it has been pasteurized (which is a process that kills germs). Listeria can cause a serious illness called listeriosis, which can be dangerous for pregnant women and their babies.

To avoid milk-borne diseases, it's important to make sure that the milk you drink is safe. One way to do this is to buy milk that has been pasteurized. This means that it has been heated up to kill any germs that might be in it. It's also a good idea to wash your hands before you handle milk or any other food, and to keep milk refrigerated so that germs can't grow in it.

So, there you have it kiddo. Always remember to drink safe milk and stay healthy!
