The prime causes of foodborne illness are a collection of bacteria with tongue-twisting names. These organisms can become unwelcome guest at potlucks, picnics, and the dinner table.

They are in a wide range of foods, including meat, eggs, milk and dairy products, coconut, chocolate, seafood, and even water.

Careless food handling sets the stage for the growth of disease-causing organisms. For example hot or cold foods left standing too long at room temperature provide an ideal environment for bacteria to grow. Improper cooking also plays a role in foodborne illness.

Foods may be cross-contaminated when cutting boards and kitchen tools that have been used to prepare a contaminated food, such as raw chicken, are not cleaned before being used for another food such as vegetables.

Symptoms

Common symptoms of foodborne illness include diarrhea, abdominal cramping, fever and vomiting. However, symptoms will vary according to the type of bacteria and the amount of contaminants eaten. For most healthy people, foodborne illnesses are neither long-lasting nor life threatening. However, they can be severe in the very young, the very old, and those whose immune systems are suppressed.

Prevention Tips

The idea that the food on the dinner table can make someone sick may be disturbing, but there are many steps you can take to protect your family and dinner guests. It is just a matter of following basic rules of food safety.

Prevention of food poisoning starts with your trip to the supermarket. Pick up your canned and packaged foods first. Don’t purchase food in cans that are bulging or dented, or in jars that are cracked. Look for expiration dates on the labels. Likewise, check the “use by” or “sell by” date on meats and dairy products such as cottage cheese, cream cheese, yogurt, and sour cream. Pick the ones that will stay fresh longest in your refrigerator.

When choosing eggs, open the carton and make sure that none are cracked or leaking.

Place frozen foods and perishables such as meat, poultry and fish in your cart last of all. Always put these products in separate plastic bags so that drippings don’t contaminate other foods in your shopping cart. Bag cold and frozen foods together, and if it will take more than an hour to get your groceries home, take along an ice chest to keep frozen and perishable foods cold.

Safe Storage

Be sure to refrigerate or freeze perishables as soon as you return from the grocery store. Refrigerator temperature should be 40°F and the freezer should be 0°F.

For foods that can be stored at room temperature, some precautions will ensure they remain safe.

Store potatoes in a cool dry place—not under the sink or in the refrigerator. Don’t store foods near household cleaning products and chemicals. When you are putting canned food items away, store the older canned items to the front and canned items with the longest-out dates of use in the back row so you’ll be sure to use the older ones first.

Keep It Clean

The first rule of safe food preparation is to keep everything clean. This rule applies to the areas where food is prepared and most importantly, to the cook. Wash hands thoroughly before starting to prepare a meal, and always after handling raw meat and poultry. Keep the work area clean. Wash fruits and vegetables thoroughly. Do not put cooked meat on an unwashed platter that has held raw meat.

The second rule of safe food preparation is keep hot foods hot and cold foods cold.

After the meal, leftovers should be refrigerated as soon as possible.

Here are a few more tips to keep your favorite dishes safe: 1) Don’t thaw meat and other frozen foods at room temperature. 2) Thaw in the refrigerator or microwave. 3) Never taste food that looks or smells spoiled.

All these dos and don’ts may seem overwhelming, but remember, if you want to stay healthy, when it comes to food safety the old saying “rules are made to be broken” does not apply!
