What Is Raw Milk?
"Raw" milk is milk that has not been pasteurized. Most raw milk has bacteria in it. Milk is a protein. Bacteria grow well in proteins. In several provinces it is against the law to even give raw milk away. Today, we do not see many health problems because of raw milk, but they do happen. In Peterborough, Ontario in 1981, eight newborn babies in one hospital got salmonella (a type of food poisoning). Doctors later found that one of the mothers drank raw milk during her pregnancy. She got salmonella, but did not show any signs of illness. She passed the sickness to her newborn child, who also showed no signs of illness. He passed the infection to other babies who became ill. One of these babies died.1 There were many problems like this before milk was pasteurized.

What Is Pasteurization?
Pasteurization kills bacteria and makes milk safe to drink. When milk is pasteurized, it is heated very quickly to a temperature of 63 degrees celsius (145 degrees fahrenheit) for 30 minutes. Then it is cooled. If pasteurized milk is kept at a temperature of less than ten degrees celsius, it stays fresh for a few weeks.2 In Canada, it is not legal to sell unpasteurized milk.

Milk is an important food for children because it provides protein and calcium. They help muscles and bones to grow properly. Today, we take fresh, pure milk for granted. In the past, parents could not. It was hard to keep unpasteurized milk fresh and safe to drink.

Living Conditions in the Past

If you could visit St. John's in the early 1900s, you would find a very different city. There were no cars. Most streets were not paved. Horse drawn wagons were everywhere. You would recognize many of the houses downtown because they are still standing today. But inside the houses, life was very different.

Water And Sewage
St. John's has had a public water supply since the 1860s, but even in 1915 there were about 2,000 houses in the city that did not have running water or sewer connections for toilets. Many people had to carry all their water from pumps on the streets. If you have ever had to go without running water, you know what that is like. It is hard work to carry every pail of water used for drinking, cooking and washing.
