Can Warmed Cow Milk Be Refrigerated Again

Cow milk is a staple in a lot of people’s kitchens. We use it for a range of purposes. And despite this day-to-day use, many still have confusing questions about milk.

One of these questions is, can warmed cow milk be refrigerated again?

The answer is yes. You can refrigerate warmed milk again. However, refrigeration is only safe if you haven’t left the milk for over 2 hours at room temperature.

This post will share with you all you need to know about safely handling warmed cow milk.

Why Not Keep Milk at Room Temperature for Over 2 Hours?

Milk is a perishable food, which means that it’s more susceptible to growing bacteria than most other food varieties.

Keeping milk at room temperature for more than 2 hours allows for the growth and multiplication of bacteria in the beverage. As a result, milk becomes unsafe to consume.

How to Refrigerate Warmed Milk Safely?

To refrigerate milk after heating it, you should first cool it down. That said, leaving it to cool down on its own will grow a lot of harmful bacteria.

This is because it’ll probably exceed the recommended 2 hours out of the refrigerator. Thus, the safest plan is to cool the milk down by exposing it to cold water.

To do so, first, put the warm milk in a closed container. Then, place it in a bowl containing iced or cold water for a few minutes.

In addition, follow these safety procedures when storing your milk in the refrigerator:

  • Store the milk in an airtight container. This protects it from absorbing odors from surrounding objects in the fridge.
  • Move the milk into a clean container before chilling it.
  • Place the milk away from the refrigerator door, as this place’s temperature fluctuates each time you open the fridge.
  • Only keep the milk that you’ve warmed for 2 days maximum in the refrigerator. Get rid of the milk, if you don’t consume the milk during this period.

  1. Set the microwave to medium power.

  3. Stir the milk every 15 seconds.
  4. Keep heating until the steam starts to rise.
