How long can your cookout spread stay out? Here's what food safety experts say
If chowing down on picnic food isn't the best part of summer, I don't know what is. And as delicious as a juicy slice of watermelon or a snappy hot dog can be, warm-weather fare is even more enjoyable when it's not accompanied by a side of food poisoning. Not to be a Debbie Downer, but leaving your famous pasta salad out of the fridge on a hot day is practically an engraved invitation for illness-causing bacteria to crash the party. So, just how long can barbecue, sides and desserts stay on the buffet table? As a former professional baker, I have a food handler's license, but I wanted to get up-to-date info on preparing, serving and storing food in the most sanitary way. I enlisted two food safety experts to share their insights, and these are their tips for your next summer bash and beyond. Ever been to a barbecue where the mayo-packed potato salad was left outside all day? Yeah, you'll want to avoid that. The window during which it's safe to leave food out at room temperature is likely shorter than you'd think, thanks to something called the (dun-dun-dun): Danger Zone. According to the USDA, the Danger Zone refers to food temperatures "between 40°F (4.4°C) and 140°F (60°C)." Why? "There are certain foods that can cause foodborne illness if allowed to sit in the temperature Danger Zone, because potentially harmful bacteria can grow at these temperatures," says Ellen Shumaker, director of outreach for the Safe Plates program at North Carolina State University. "These include cut leafy greens, cut tomatoes and cut melon, raw and cooked meat and poultry, milk and dairy products, cooked dishes like casseroles, cooked vegetables, beans, pasta, rice and potatoes, as well as baked goods with cream, custard, cheese, meat/vegetable fillings and cream frostings." If you're thinking, "That's so many foods!" — well, you're right. But you can still safely enjoy them as long as you adhere to certain guidelines. Typically, that means keeping food out for no more than two hours, says Amanda Deering, associate professor of fresh produce food safety at Purdue University's Department of Food Science. That said, she adds, "If temperatures are above 90°F, it should sit out for no more than an hour." When it comes to safely preparing food, some ingredients are less straightforward than others. Of course, you'll always want to make sure you're using freshly cleaned hands and tools no matter what you're making, but for meat, there are other factors to keep in mind. "A meat thermometer is going to be your best friend," says Deering. "That's the only true way you can tell you cooked it properly." Shumaker agrees, adding, "With outdoor cookouts and grilling, I always think about making sure that meats are cooked to a safe endpoint temperature to kill off harmful bacteria. Burgers and other ground meat should be cooked to 160°F, and poultry should be cooked to 165°F." Grilling steak? The USDA says to cook beef, pork, veal and lamb steaks to an internal temperature of 145°F and let them rest for at least three minutes. The same temperature applies to fish and shellfish. "Other safety tips to keep in mind are to make sure that people handling and serving food are washing their hands and avoiding cross-contamination (making sure that utensils or cutting boards aren't used with raw meat and then fresh salad)," Shumaker cautions. And you are washing your hands ... right? It probably makes sense that keeping meat out at room temperature for too long isn't a great idea, but what about all of those accoutrements? "People sometimes don't think about fresh fruits and vegetables," says Deering, who advises heeding the Danger Zone guidelines for cut produce as well. To keep your produce fresh for longer, she says you'll want to "wash it under cool, running water and scrub with a vegetable brush, right before you're going to consume it." Rinsing it off too early can encourage the growth of bacteria, so it's best to hold off until you're about to cut it up. As for starchy side dishes? If you're on social media, you may have come across videos about something referred to as fried rice syndrome. Funny name, yes, but it's no laughing matter. "Fried rice syndrome refers to foodborne illness caused by, as the name implies, consuming fried rice," explains Shumaker. "In this case, it is caused by the bacteria Bacillus cereus. Bacillus cereus can be found anywhere. It is usually found in spore form, which is a dormant, or inactive, form of the bacteria. When the right conditions occur, the spore form of bacteria can become active. When some foods, like rice and other cooked dishes, are left sitting out for too long, Bacillus cereus can become active and produce a toxin. That toxin is what causes foodborne illness — specifically diarrhea, nausea and vomiting." (I don't think that's how any of us envision spending our summer...) How to avoid getting sick? You got it: Keep foods like rice, pasta, potato salad, casseroles and even condiments from sitting in the Danger Zone for too long. (At this point, shouldn't someone get Kenny Loggins to rework his Top Gun theme song to increase awareness around food safety?) Oh, and if you're thinking, "I'll just pop this cheesy dip I forgot to put in the fridge back into the oven to cook off that bacteria," guess again. "Bacillus cereus is heat-resistant, so unfortunately, simply reheating a food after it has been temperature abused will not destroy the toxin," Shumaker says. Deering is less concerned about certain types of foods. "Typically, things that are very high in sugar don't support the growth of human pathogenic bacteria," she says. This means your brownies and cookies are less likely to make you sick if they stay out longer. That said, anything creamy or custardy (think: trifles, lemon bars, banana cream pie) needs to be given the Danger Zone treatment. So, you prepare a batch of baked beans the day before a barbecue. What's the best way to keep it fresh? When it comes to hot food, "you want to get it as cool as possible, as quickly as possible," Deering says. Shumaker adds, "Because toxin formation occurs in the temperature Danger Zone, it is important to cool foods quickly." That said, you don't want to place a piping-hot pot straight into the fridge. Why? "It is not recommended to put large containers of hot food in the fridge because the food in the center of the pot will not cool down quickly enough to avoid the temperature Danger Zone," explains Shumaker. "Divide large portions of hot food into shallow containers to allow foods to cool more quickly before putting [them] into the fridge." Deering agrees. "If you have a smaller container that's packed full, that's going to take a long time for that internal part of the food to get cold, so then you risk that you're in that Danger Zone. If you have a bigger container with not as much food, that's going to cool a lot faster." As far as what the container is made of, neither Deering nor Shumaker has a clear preference, though they both stressed the importance of having a good seal to keep air out. That said, concerns about ingesting microplastics are on the rise, you may want to consider using glass containers — especially if you plan on microwaving them or using them for hot foods, which can cause plastic containers to release more of those tiny particles. That was a lot of information — the key takeaways? "Try to keep foods cold as long as possible by using coolers with ice or ice packs, and consider only serving small portions at a time," says Shumaker. "Otherwise, I just make sure my fridge is kept at 41°F or below to maximize shelf life." When in doubt, Deering has an easy-to-remember motto: "Keep cold things cold and hot things hot!"
