E. coli and other harmful germs can be on your kitchen surfaces and in your foods. At home, follow these 4 simple steps to prevent illness.

Do not drink unsafe water.

At home

Having safe drinking water may be as simple as turning on the tap. But sometimes, extra steps are needed to make sure water is safe.

Camping, hiking, or traveling abroad

When camping, hiking, or traveling, always use safe water for drinking, cooking, brushing your teeth, or other activities. Use one of these methods to treat or purify water.

Swimming

Don't swallow water when swimming or playing in lakes, ponds, streams, swimming pools, and backyard "kiddie" pools.

Diarrhea and swimming don't mix!‎

Don't swim or let others swim if sick with diarrhea.

Drink pasteurized milk and juices.

Pasteurized milk and juices have undergone a process called pasteurization. Pasteurization kills harmful germs, including E. coli. Look for the word "pasteurized" on the label when shopping for milk, dairy products, and juices. If in doubt, don’t buy it!
