Detailed explanation-1: -Microbial spoilage is caused by microorganisms like fungi (moulds, yeasts) and bacteria. They spoil food by growing in it and producing substances that change the colour, texture and odour of the food. Eventually the food will be unfit for human consumption.
Detailed explanation-2: -The three major types of microorganisms which cause food spoilage are bacteria, yeasts and moulds.
Detailed explanation-3: -1.1 Introduction. Food spoilage results when microbiological, chemical, or physical changes occur, rendering the food product unacceptable to the consumer. Microbiological food spoilage is caused by the growth of microorganisms which produce enzymes that lead to objectionable by-products in the food.
Detailed explanation-4: -There are four main types of contamination: chemical, microbial, physical, and allergenic. All food is at risk of contamination from these four types. This is why food handlers have a legal responsibility to ensure that the food they prepare is free from these contaminants and safe for the consumer.
