● Handle extra food wisely.

Anita, a mother in Poland, serves most meals immediately after cooking. But if there is extra food, she says, “soon after preparation I freeze it in small portions to make it easy to defrost.” If you store leftovers in the refrigerator, eat them within three to four days.

● Beware of doggie bags.

The U.S. Food and Drug Administration advises: “If you won’t be arriving home within two hours of being served [sooner if temperatures are above 90 degrees Fahrenheit (32°C)], don’t take the leftovers home with you.” If you have leftovers, go directly home after your meal and store them in the refrigerator.
