Why Warmed Breast Milk Should Not Be Put Back in the Fridge?

Warming breast milk puts it in the ideal temperature for feeding, but also accelerates bacterial growth. The rate of growth is significantly faster compared with breast milk that's in the fridge. It is also faster than in milk that has stayed at room temperature.

It does not mean that warming breast milk should be avoided. It is still safe to consume within 2 hours after being warmed. After that, consider it unusable. Feeding your baby with unused, warmed milk may cause foodborne illnesses.

Now, you may think about putting it back in the fridge to fix it. The problem is that refrigerating breast milk only slows down bacterial growth. It does not kill bacteria that are already in the milk. That said, the milk is still not safe to consume. Also, keep in mind that refrigerating does not fully stop bacterial growth. It continues, just much more slowly. As such, the milk will become more and more dangerous to your baby's health as time passes by.

With all that said, throw away breast milk that was warmed but was not used. Do not put it back in the fridge.
