Can milk go bad in monsoons?

There’s no denying that the monsoon brings with it a respite from the scorching summer heat. But it is also the time when moisture and humidity are in the air, which is the core reason for spoilage. The rainy weather makes it easy for bacteria and pathogens to breed, which leads to several ailments and allergies. This is why consuming certain foods around this time calls for more caution. One such staple is milk, which is prone to spoilage in this season. Here’s all you need to know about it!

Why milk spoils faster in monsoons
Humidity and fluctuating temperatures during the monsoons create the ideal breeding ground for bacteria and fungi. Even pasteurized milk is vulnerable once opened. Bacteria that survive the pasteurization process multiply rapidly in damp and warm conditions, leading to curdling, a sour smell, and spoilage.


Increased moisture in the air
High humidity levels also interfere with the freshness of milk. Excess moisture in the environment can lead to condensation inside milk containers, especially if they’re frequently opened. This moisture encourages microbial activity, speeding up spoilage even in the fridge.

Contamination
Monsoon often comes with power cuts, which disrupt refrigeration. Alongside this, using unclean utensils, repeatedly reheating milk, or storing it in non-sterile containers can contaminate it with external microbes, worsening the spoilage risk.


How to prevent milk from spoiling
Boil Immediately: If you’re using fresh milk (especially non-pasteurized), boil it as soon as you get it home. This kills most bacteria and gives it a longer shelf life.

Store in Glass or Stainless Steel: Avoid plastic containers, which can retain moisture and odors. Glass and steel are easier to sterilize and keep the milk fresh.

Refrigerate Right: Store milk at the back of the refrigerator where it’s coldest—not near the door. Always keep the milk container tightly closed.

Avoid Cross-Contamination: Use clean ladles, and don’t dip fingers or spoons used in other foods into milk. Even a small transfer of bacteria can spoil the batch.

Freeze Small Portions: If you buy milk in bulk, consider freezing small portions. Thaw only what you need. This is especially useful during power cuts.
