As you head out for summer picnics and barbecues, remember food safety.

E. coli infections from food poisoning spike in the summer months.

It can happen pretty easily if you're not careful. Raw meats, raw fruits and vegetables can be contaminated with the E. coli bacteria.

E. coli can incubate in your system for up to 10 days before symptoms appear, and those symptoms include vomiting and diarrhea that last.

"Our typical infections a lot of times run their course in 24 to 48 hours," said Dr. Andrew McAfee of Family Medicine. "The E. coli infections tend to stick around longer, more like five to seven days, so it can lead to more cases of dehydration."

Dr. McAfee says be sure to fully cook meat on the grill because it kills the bacteria.

You can use a meat thermometer.

Food safety experts say don't slack off in the summer. Clean all surfaces in contact with raw meat, and wash your hands.
