Frozen dinners, also known as frozen meals or TV dinners, should not be kept in the fridge for an extended period after thawing. Once you take a frozen dinner out of the freezer and place it in the refrigerator to thaw, you should plan to consume it within 1 to 2 days.
The general guidelines for refrigerator storage of perishable foods apply to frozen dinners as well. The refrigerator's temperature should be set at 40°F (4°C) or below to slow down the growth of bacteria and maintain food safety. If the temperature of the refrigerator rises above this level, it can lead to bacterial growth and potential foodborne illness.
If you have thawed a frozen dinner and don't plan to eat it within the recommended time frame, it's best to put it back in the freezer until you're ready to consume it. Freezing the meal again will help maintain its quality and safety.
Always follow the storage instructions on the packaging of the frozen dinners and use your best judgment. If you notice any unusual smells, changes in texture, or signs of spoilage, discard the meal to avoid any potential health risks.
