If the stomach acid is strong enough to dissolve food, why can't it kill dangerous germs that cause all sorts of different diseases?

Not All Bacteria are Eliminated in the Stomach

Although stomach acid is powerful enough to kill many harmful bacteria, some bacteria may not be completely eradicated.

Not all bacteria that come into contact with food will enter the stomach.

Some may linger in the mouth or adhere to the food, making their way into the digestive system.

Bacterial Toxins

Furthermore, bacteria can produce toxins as food spoils.

Even if the stomach acid were to successfully kill the bacteria, the toxins they have produced can still pose a significant danger.

These toxins can continue to linger on the food and may not be neutralized by stomach acids, potentially leading to food poisoning and other adverse health effects.

Acid-Resistant Bacteria

In addition, some bacteria have developed resistance to stomach acid.

These acid-resistant bacteria can survive the acidic environment of the stomach and continue to pose a threat even after being ingested.

Spoiled food can harbor a range of bacterial threats, from those that resist the stomach's acidic environment to the toxins produced by bacteria.

While stomach acid plays a critical role in neutralizing many potential dangers, it is not always a failsafe.

It's important to handle and store food properly to prevent the growth of harmful bacteria and minimize the risk of foodborne illnesses.
