Milk has been one of the essential foods for many years, and it still is. Its benefits are widely recognized even though some of the recent researches suggest that milk produced today might contain harmful chemicals. In this article, we’re not going to discuss its benefits or drawbacks, but rather what happens if you drink spoiled milk.

As some of you might already know, milk producers use the process of pasteurization to prolong the longevity of the milk and to eliminate bacteria from it. However, while this process is effective, it still doesn’t kill all of the bacteria found in this dairy product. Leftover bacteria don’t pose any threat to humans, but over the course of several days, they multiply, and when that happens milk gets spoiled.

How to recognize spoiled milk?

There are few simple things you can do to recognize spoiled milk, or for that matter any spoiled food. Firstly visually inspect it – the milk will change its appearance slightly, as well as the texture when it goes bad. If it looks good take a good whiff of it. Bad smell is one of the main indications that it is not good for human consumption.

The smell test is also good to test any other food for spoilage. If the smell doesn’t give it away, take a small sip. Even though tasting the milk might not be the smartest or most effective method to test spoiled milk, it is still better than taking a few gulps.

So what happens if you drink spoiled milk you might ask? Well, the answer to that question might a bit more complicated than expected. There are several factors to take into consideration like the amount you consumed, the time milk is past its prime, etc.


If, for example, you took a few gulps of milk that has just gone bad, you might expect mild food poisoning manifesting through diarrhea, vomiting and stomach cramps. You can expect to experience these symptoms after a few hours or even a few days. Symptoms are expected to last for about a day or two, and if they are more severe, or last longer, you should visit your doctor immediately.

Health condition and age should also be taken into consideration. If you have some health issues, or if the person in question is a child, drinking spoiled milk might have more serious consequences, and in that case, it is best to consult your doctor.

How long is milk good after opening?

After opening, milk stays good for four to seven days, however, that still depends on the manufacturer, type of milk, and even the country. It is always smart to read the packaging and to store the milk accordingly.

What can I do to prevent this from happening?

Well, you can’t prevent milk from spoiling altogether, as we all know, but you can take measures to prevent milk from spoiling prematurely. First thing you should do when you come from shopping is to refrigerate your perishables. Do not leave milk in the hot car; this will significantly reduce its shelf life.

Also, do not leave your milk out of the refrigerator exposed to room temperature for long periods of time, this is one of the main reasons milk gets spoiled prematurely. Inspect the package for storage instructions and store accordingly. Follow these instructions and you won’t have to find out yourself what happens when you drink spoiled milk.
