ABC News reports that on “Good Morning America” Weekend Edition Dr. Michael Doyle, director of The Center for Food Safety at The University of Georgia, said items like plastic wrap, aluminum foil and Tupperware may make your foods taste fresher but they won’t extend their shelf life.
And when it comes to mold, if you find it on a brick of cheese, just cut that chunk off. But if you find it on a slice of bread, the whole loaf has to be thrown out because invisible mold may have spread to the other slices.
Perhaps the single best thing you can do to extend the shelf life of your foods is to make sure your refrigerator is set at 40 F or lower.
“I’ve seen home refrigerators as high as 55 degrees Fahrenheit! That is no longer a refrigerator,” Doyle said. “We microbiologists call that an incubator. That’s how you grow bacteria.”
