What are the 3 types of micro organismas in food spoila?

The three main types of microorganisms involved in food spoilage are bacteria, yeasts, and molds. Bacteria, such as Salmonella and E. coli, can cause foodborne illnesses and spoilage through decomposition. Yeasts, like Saccharomyces cerevisiae, often lead to fermentation and spoilage in sugary foods. Molds, including species like Aspergillus and Penicillium, grow on food surfaces, causing visible decay and producing mycotoxins.
