Memorial Day kicks off the warm weather season, giving many an excuse to gather, travel and enjoy the sun. On the road or at home, beware of holiday dangers. Keep your weekend from turning into a disaster with these four safety tips. Dr. Ty reports on MSNBC:

The lack of refrigeration at barbecue lunches invites bacteria to join the party. The biggest culprits are dishes made with mayonnaise, such as potato salad or coleslaw. Not fully cooking meat on the grille and accidentally touching cooked food with the raw meat utensils are also setups for food poisoning.

Food poisoning symptoms are not subtle. The abdominal pain, cramping, vomiting and diarrhea often hits suddenly, after two to six hours of eating the offending food. Most times, it has to simply run its course. But, remember to stay hydrated and avoid milk or dairy until the diarrhea stops.

Pregnant women, children, the elderly and those with weak immune systems have to be especially careful.

In order to prevent infection, cook meat until fully done. Keep raw food far away from cooked food. And, keep the cold items in a good quality cooler with lots of ice. Maintain the cooler as close to 40 degrees Fahrenheit as possible.
