Food microbiology is the study of microorganisms that live in, create, or contaminate food. These microorganisms include bacteria, yeasts, molds, and viruses. Food microbiology focuses on how these microbes affect food safety, quality, and preservation.

Types of Microorganisms in Food

1. Bacteria – Some are useful, while others cause food spoilage or illness.
   Example: Salmonella enterica can cause food poisoning.

2. Fungi (Yeasts and Molds) – Often responsible for fermentation and spoilage.
   Example: Lactobacillus helps in making fermented foods like yogurt.

3. Viruses – Can contaminate food and cause disease.
   Example: Norovirus spreads through contaminated food or water.

Importance of Food Microbiology

Food microbiology is important because it helps to:

• Prevent foodborne diseases

• Improve food preservation

• Maintain food quality

• Support food production (e.g., fermentation)

• Ensure food safety standards

Food Spoilage

Microorganisms can spoil food by:

• Producing bad odors

• Changing taste

• Changing coloR
