Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...

Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness. The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak. [ 1 ]
In addition to reducing the time spent in the danger zone, foods should be moved through the danger zone as few times as possible when reheating or cooling. [15] Foods that are potentially hazardous inside the danger zone: [16] Meat: beef, poultry, pork, seafood; Eggs and other protein-rich foods; Dairy products; Cut or peeled fresh produce
Preserving fruit by turning it into jam, for example, involves boiling (to reduce the fruit's moisture content and to kill bacteria, etc.), sugaring (to prevent their re-growth) and sealing within an airtight jar (to prevent recontamination). Different food preservation methods have different impacts on the quality of the food and food systems.
The spoilage of meat occurs, if the meat is untreated, in a matter of hours or days and results in the meat becoming unappetizing, poisonous, or infectious. Spoilage is caused by the practically unavoidable infection and subsequent decomposition of meat by bacteria and fungi, which are borne by the animal itself, by the people handling the meat, and by their implements.
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
Some bacteria are responsible for the spoilage of food. When bacteria breaks down the food, acids and other waste products are generated in the process. [2] While the bacteria itself may or may not be harmful, the waste products may be unpleasant to taste or may even be harmful to one's health. [3]
