Because of the heat used to can the food.
sometimes Bactria can kill microbes
Sterilization is the process that destroys and or removes all microorganisms. It also removes microbial forms such as bacterial endospores.
prior to the canning all bacteria in the food are killed and the canning prevents new bacteria from infecting and spoiling the canned food Food that is put into canning jars is not sterile, thereby allowing bacteria to grow. Canning sterilizes the food and the jar, killing any thing in the jar. Water boils at 212 which is the temperature for sterilization. If using a presure canner, the combination of the pressure and the boiling sterilize meats, veggies, etc.
It aids in digestionIt protect us from some microbes that are pathogens. Some disease causing microbes are present in contaminated or food that are not properly treated. The acid pH of the stomach kills those microbes and protect us from disease.
your stomach acids fight it off and they kill the microbes. in a way this is good and bad because if it kills the bad microbes then it kills the good microbes in our body aswell!
It is heated briefly during the canning process; this kills any bacteria inside and effectively leaves it sterile until opened.

The process initiated by Louis Pasteur that kills microbes is known as pasteurization. This method involves heating liquids, such as milk or wine, to a specific temperature for a set period to eliminate harmful microorganisms without significantly altering the product's quality. Pasteurization has been widely adopted in the food and beverage industry to enhance safety and extend shelf life.
The alcohol kills microbes that can cause infections.

Yes, pressure canning effectively kills E. coli and other harmful bacteria. The high temperatures achieved during the pressure canning process (above 240°F or 116°C) are sufficient to destroy these pathogens. It is essential to follow proper canning guidelines and times to ensure food safety. However, it's important to note that pressure canning is primarily used for low-acid foods, while high-acid foods can be safely processed using water bath canning.
because the jam is heat treated before sealed and so has no microbes on it, even when you open it the high amount of sugar dries out the microbes, which then kills them (see below) the sugar is a solute and the jam is the solution. also jam is viscous so it slows them down while the sugar kills them
