How long can food be left at room temperature safely?

Leaving food out at room temperature safely becomes trickier during summer months. When the temperatures soar during summer in some parts of the country, barbecues simultaneously become more appealing and more hazardous. Leaving meat, cheese and other dairy-based foods in the heat for too long is often a recipe for disaster.

In hot weather (above 90 degrees Fahrenheit), food should never sit out for more than one hour. If it's below 90 degrees, discard any food after two hours.

Bacteria multiply most rapidly at temperatures between 40 degrees and 140 degrees, and can reach dangerous levels. So, smart practices for storing and cooking your food are extremely important.

One hour if it is 90+ degrees F, two hours if it is under 90 degrees F.

Follow the 2-hour rule: Don't let perishable food sit out at room temperature for more than 2 hours. If the temperature is above 90 degrees, limit that time to only one hour.

Storing food carefully will ensure freshness and taste, plus it will keep bacteria at bay. Use sealable containers that are shallow (two inches or less, if possible) to help cool food quickly. Don't over-pack the fridge; air needs to circulate to maintain the proper temperature, which should be 40 degrees Fahrenheit (check it before you close up for the night). Turkey will stay good for three to four days, but gravy shouldn't be eaten after one or two. The same goes for baked goods, which should be eaten or thrown out within a few days of the big day.
