Recently discussed on the Today Show by registered dietitian Tamara Freuman were the eight myths of food poisoning.

1. It can’t happen to me. Food poisoning is one of the most common maladies in the U.S. About one in six will get sick eating contaminated foods according to the Centers for Disease Control. That equals 48 million people most of whom get better on their own after feeling awful, but about 128,000 are hospitalized and 3,000 die.

2. If it’s food poisoning, I’ll get sick quickly. Staph (Staphylococcus aureus) will make you sick in about 1 to 2 hours. Noroviruses will hit you in about 12 to 48 hours. E.coli O157: H7 a very bad bug found in undercooked beef, raw fruit, veggies, contaminated water and non-pasteurized beverages can take 1 to 8 days.

3. Is it hot (or cold) enough. The danger zone for food is between 40 degrees and 140 degrees. This is the temperature range that bacteria can grow in. Foods should not be left in the danger zone for more than two hours or one hour if the outdoor temperature is about 90 degrees. It is safer to use a thermometer to check the food and if in doubt, throw it out.

4. Fruits with rinds are always safe. Unfortunately, a very serious problem, listeria, can be right on the rind and cause about 1,600 people to get sick each year and 260 die. So better to wash the fruit even if you are going to peel it.

5. It’s the mayo’s fault. The commercial mayo actually wards off some bacteria because of its high acid content, but once potatoes are added there is the risk of cross contamination usually with Staph aureus which can grow in the “Danger Zone.” Once again use a thermometer.

6. Food poisoning symptoms are always the same. Actually the symptoms are linked to the pathogen that has been eaten. The symptoms can be profuse diarrhea with no fever to diarrhea, vomiting, cramps, fever and even a reactive arthritis.

7. Water will solve all my woes. If you do get sick you do lose water, but you also lose sugar and salts. Better to drink a solution with electrolytes as well as water and broth. If there is blood in the stools, vomiting is continuous, or the sickness is lasting more than a couple of days, call your health care provider. Particularly for the very young, older adults and those with other health problems.

8. Picnics are dangerous. The overall advice is to have burgers that are well done, cold foods are cold and hot foods are hot (danger zone is 40 degrees to 140 degrees). It is wise to use a thermometer. Keep surfaces clean and everything securely wrapped to avoid cross contamination. Wash your hands and have fun.
