Natural causes can increase food poisoning cases in the summer. Bacteria can grow faster in warm weather. Uncooked meat may contain harmful organisms that cause people to become sick. Another reason for the increase in food poisoning in the summer is human activity. People spend more time outside and away from home in warm weather.
Many people bring food to eat outside in parks or at the beach.
Others cook meals outdoors in open fires near their homes or on camping trips. Unwashed hands are a leading cause of the spread of bacteria. People should wash their hands with hot water and soap before touching food. It is important to find clean water when eating away from home. If there is none, make sure to bring water for preparation and cleaning.
