Breast milk doesn't ferment. This is false information circulating on the internet. Breast milk has a self-protecting structure thanks to its natural antibodies and living cells. It contains substances like lysozyme, lactoferrin, and IgA that prevent bacteria from growing. That's why, unlike yogurt or vinegar, it doesn't ferment with an outside culture.
Fresh expressed milk can be safely stored at room temperature (below 25°C) for 4-6 hours, in the refrigerator (4°C) for 3-5 days. After these periods, it spoils—meaning it turns sour, smells, separates; but this isn't "fermentation."
In short: Breast milk doesn't ferment, it spoils. Fermentation isn't a process that happens with this milk. You can put your mind at ease on this.
