Milk spoils when microbes begin to grow in it decomposing the fats and sugar. The change is biochemical. The smell is associated with the waste products of decomposition.
Spoiled milk smells bad because of the presence of bacteria that break down the proteins in the milk, producing compounds that give off a foul odor.
Spoiled milk smells bad because of the presence of harmful bacteria that break down the proteins and fats in the milk, producing compounds like butyric acid and hydrogen sulfide, which have strong, unpleasant odors.
Sour milk has a strong, unpleasant odor that is often described as tangy or sour. To tell if milk has gone bad, you can check for changes in texture, color, and smell. If the milk looks clumpy, has a yellowish tint, or smells off, it is likely spoiled and should not be consumed.
Charcoal is effective in eliminating bad smells because it has porous properties that can absorb and trap odor-causing molecules.

I think seafood spoils quicker than milk, but milk spoils due to the bacteria that are naturally found in milk. Pasteurization eliminates pathogens and reduces the overall bacterial load. Since it is not sterilized, milk will eventually spoil even when refrigerated.

if you drink milk that smells obviously bad (which is usually the first sign of truly expired milk that she will most likely have bloating and indigestion. If she is sure it is bad, and she really really wants to hold on to that milk in the fridge tell her to leave it out for a good day or two. After it curdles it goes through another stage, where it turns into a consumable product again because friendly bacteria naturally develop in it. That is what buttermilk is, it's like a liquid yogurt. After that she should probably through it out, unless she can get instructions on how to make cheese.
