“Here’s what Martin Bucknavage, a food safety specialist at the Penn State Department of Food Science, had to say on the subject-Post holiday turkey:
“The post turkey stays good in the fridge for three to four days as a safe window if covered and refrigerated at a proper temperature. “If one is going to want to keep it longer, then it is worth considering freezing,” he says.
“Freezing is a great way to hold turkey for longer periods of time.” It’s important that if you do freeze turkey leftovers, they’re stored in a container that’s as airtight as possible.
When it comes to defrosting, it’s best to defrost in the refrigerator. However, Bucknavage explains, leftover turkey can be defrosted “under cool running water if in a hurry or thawed in the microwave, provided that it is served immediately.”
