85 Percent of People Are Making This Dangerous Barbecue Mistake, USDA Says
This common error could be putting you at risk this summer, the food authority says.

If firing up the grill this holiday weekend is a major component of your Fourth of July plans, you're not alone. According to a survey conducted by the National Retail Federation, 61 percent of people living in the U.S. are planning to celebrate the holiday with a barbecue, cookout, or picnic this year. While fireworks may seem like the most obvious threat associated with the holiday celebrations, the United States Department of Agriculture (USDA) says there's a mistake approximately 85 percent of U.S. residents are likely to make this weekend—and doing so could put your health in jeopardy. Read on to find out if you're making this critical error, and what you can do to keep yourself safe.

Don't serve cold food that hasn't been kept on ice.

While many people will instinctively steer clear of certain foods that have been left to sit in the sun at a barbecue or picnic, that's not the only potential food hazard you may encounter—or inadvertently cause—at your next outdoor gathering.
According to a survey conducted by the USDA's Food Safety and Inspection Service (FSIS), just 16 percent of individuals polled said that they followed the FSIS-recommended practice of serving cold food on a plate or bowl with ice surrounding it and storing or throwing away any leftovers within a two-hour period. Even this seemingly conservative advice is only good for more temperate days—if the temperature reaches above 90 degrees Fahrenheit, the USDA cautions that food left out is only safe to eat for a single hour.

You should keep hot food sufficiently warm, too.

It's not just cold food, like vegetables, pasta salad, or fresh fruit, that requires specific serving conditions in order to ensure it's safe to eat.
The same FSIS survey found that 66 percent of those polled said they didn't make an effort to keep their hot foods hot, either. Unfortunately, stashing those hot foods somewhere sunny isn't sufficient to keep disease-causing bacteria at bay. The USDA recommends keeping all hot foods at a temperature above 140 degrees Fahrenheit and refrigerating any leftovers within two hours.
Pathogenic bacteria in food can double in 20 minutes.

If you're not adhering to specific practices for keeping your cold foods cold and hot foods hot, you could be putting yourself at risk for foodborne illness. The FSIS explains that food enters the so-called "danger zone" when it reaches between 40 and 140 degrees Fahrenheit. At this temperature, certain types of pathogenic bacteria can double over a period of just 20 minutes.
Unfortunately, the presence of pathogenic foodborne bacteria, like E. coli, listeria, and salmonella, can't always be detected by looking at or smelling a particular food. Even if your food is no longer sitting in the sun, the amount of sickness-causing bacteria within it could be rapidly growing. "Food that has been left too long on the counter may be dangerous to eat, but could look fine," the FSIS cautions.
Foodborne illness kills thousands of U.S. residents each year.

While many people associate foodborne pathogens with unpleasant gastrointestinal side effects, they can—and frequently do—cause far more serious types of illness.
According to the Centers for Disease Control and Prevention (CDC), approximately 48 million people in the U.S. become sick from foodborne diseases each year and 128,000 require hospitalization. Additionally, approximately 3,000 U.S. residents die from foodborne illness each year, with salmonella, toxoplasma gondii, listeria monocytogenes, norovirus, and campylobacter spp. associated with the greatest number of fatalities.
If you're concerned that your food may have been left out too long or kept in less-than-ideal temperature conditions, err on the side of caution and toss it.
