Learn about the symptoms of foodborne illness. The most common symptoms include: stomach cramps, nausea, vomiting, diarrhea and fever. See a health care professional as soon as possible if you think you have a foodborne illness. Follow these four steps when handing and preparing food: clean, separate, cook and chill. Step One - Clean: Wash hands and surfaces often to avoid the spread of bacteria. Wash your hands with warm water and soap, rinsing for at least 20 seconds, before handling food, and after handling raw meat or poultry, using the bathroom, touching pets or changing diapers. Alcohol-based hand cleansers are useful when soap and water are not available. In most cases antibacterial soap is not necessary for safe, effective hand hygiene. Always wash raw fruits and vegetables with clean water. You cannot tell whether foods carry surface bacteria by the way they look, smell or taste. Step Two - Separate: Keep raw meats, such as ground beef or pork, poultry, fish and seafood separate from cooked or ready-to-eat foods to avoid cross-contamination. When you pack a cooler for an outing, wrap uncooked meat, poultry, fish and seafood securely and put them on the bottom to prevent raw juices from dripping onto other foods. Ideally, use a separate cooler for the raw foods. Wash all plates, utensils, and cutting boards that touched or held raw meat, poultry, fish or seafood before using them again for other foods. Wash hands after handling raw meat and wash the food thermometer (preferably a digital one) after each temperature reading. Step Three - Cook: Make sure you kill harmful bacteria by properly cooking food. Checking the colour is not a guarantee that food is properly cooked and safe to eat. Don’t guess! Use a digital food thermometer to check when meat, poultry, fish and seafood are safe to eat. Cooked foods are safe to eat when internal temperatures are: Beef, veal and lamb (pieces and whole cuts) 63° C (145° F) for medium rare 71° C (160° F) for medium 77° C (170° F) for well done 70° C (158° F) for fish 71° C (160° F) for ground beef, veal, lamb and pork 71°C (160° F) for pork (pieces and whole cuts) 74° C (165° F) for shellfish, leftover food, and boned and deboned poultry parts 85° C (185° F) for whole poultry Step Four - Chill: Keep cold food cold. Perishable foods that are normally in the refrigerator, such as luncheon meats, cooked meat, chicken, and potato or pasta salads made with mayonnaise must be kept in an insulated cooler with freezer packs or blocks of ice to keep the temperature at 4° C (40° F). Keep the cooler out of direct sunlight and avoid opening it too often. Use separate coolers for food and drinks to keep the perishable food colder for longer because the cooler won’t be opened as often. Put leftovers back in the cooler as soon as you are finished eating. On hot summer days, don’t keep food unrefrigerated for more than one hour. The simple rule is: When in doubt, throw it out!
