Holiday leftovers can't be left over for long

When the holiday guests depart, make sure the leftovers from the holiday feast safely do the same.

"Four days is the rule-of-thumb when it comes to leftovers," said Michael Doyle, a food microbiologist with the University of Georgia College of Agricultural and Environmental Sciences. "After that, you should eat them, toss them or freeze them."

Doyle, director of the UGA Center for Food Safety in Griffin, Ga., is a world-renowned expert in foodborne pathogens. CFS researchers work to develop methods to detect and control harmful microbes in the U.S. food supply.

Two-hour limit

To keep foodborne illness away from your holiday parties, Doyle recommends refrigerating or freezing holiday meals two hours after serving.

"It's great to spend time with family members after a holiday dinner," he said. "Just take the time to put away food dishes first."

Whether you're making leftover ham or turkey dishes, be sure to reheat leftovers to at least 165 degrees Fahrenheit, Doyle said.

Cooking, storing temperatures key

"Temperatures are critical when it comes to keeping food safely stored and cooking food," he said. "Refrigeration is so critical, and many home refrigerators are way out of the safe zone of 41 F. A refrigerator set at 50 F is what we microbiologists call an incubator. That's where we grow bacteria for research."

Doyle says home freezers should be set at zero degrees or below.

"Setting the refrigerator a little higher is no way to save money," he said. "Your family's health isn't worth the energy savings."

The holiday season can be a time of anticipation and joy, but balancing multiple commitments and personalities across families and friends can be a source of stress for hosts and visitors alike. Like preparing parts of the meal ahead of time to spend more of the holiday with guests, taking time ahead of the day to set expectations can go a long way to ensuring enjoyable gatherings, said Ted Futris, University of Georgia Cooperative Extension specialist and professor of human development and family science in the College of Family and Consumer Sciences.

The women and stress behind rural farming in America 11/19/24 Leigh Hataway
Recent research from the University of Georgia suggests the unique stresses from farm life may be taking a toll on one of the pillars of the families that make your dinners possible: the women who keep farming families running. “If we don’t control our food sources, we don’t control our health and safety,” said Anna Scheyett, lead author of the study and a professor in UGA’s School of Social Work. “It’s a matter of national security that farmers survive in the United States. And one of the big factors in helping farms survive is women.”

Wheat breeders spend years meticulously crossing varieties to coax the best traits out of each species, carefully propagating plant varieties that are healthier, heartier and better suited for the environments where they are grown. Professional brewmasters are equally painstaking when choosing the components that will give their beers a specific flavor profile.
