You go to the local steakhouse to eat your favorite special, and you really enjoy it...until...
Ever wake up to realize that you are really sick and don't know why? First, trace it back to what you ate the day before and determine if you had anything unusual or something you don't always eat. Be on the lookout for foods like: meats, eggs, and dairy products.
At home, make sure you cook meat and eggs to the proper temperature to prevent bacteria such as salmonella and E. coli. The effects of these can be very serious, especially in children and the elderly.
You can determine the food poisoning came from a restaurant if someone else dining with you also became sick, and you ate the same thing. The best thing to do is contact the manager to discuss what you experienced. It is in your best interest, and the interest of other customers, to notify them. Restaurants have rules about handling food, and prepare food fresh every day. However, even if it's not an issue with the restaurant, it may be an issue with their supplier.
If the restaurant manager is unresponsive, or dismisses the possibility that it came from them, you can contact their corporate office. Most restaurant chains will have a website and make their customer service number available for questions or concerns.
