Which hazards is an example of microbial contamination?
Microbial hazards in food include bacteria such as Salmonella, viruses such as Norovirus, parasites such as trematodes as well as prions. Diarrhoeal diseases are the most common illnesses resulting from the consumption of contaminated food, causing 550 million people to fall ill and 230 000 deaths every year.

What is microbiological food safety?
Food safety is a major focus of food microbiology. Numerous agents of disease and pathogens are readily transmitted via food which includes bacteria and viruses. Microbial toxins are also possible contaminants of food; However, microorganisms and their products can also be used to combat these pathogenic microbes.
What are microbiological hazards?
Microbiological hazard occurs when food becomes contaminated by microorganisms found in the air, food, water, soil, animals and the human body. Many microorganisms are helpful and necessary for life itself.

What are the precautions for biological hazards in food safety?
Precautions for biological hazards include proper handling practices such as handwashing, regular cleaning, chilling of foods, and thorough cooking. Biological hazards are very common in the food service area and food production sites. Their presence is even larger during the harvesting of raw materials.
Why is food contamination a public health concern?
The contamination of food by microbial agents is a worldwide public health concern. Most countries have documented significant increases in the incidence of diseases caused by microorganisms in food over the past few decades.
What are some examples of food safety hazards?
Food safety hazards can either be innately present on foods or can be introduced from external sources. Different foods have their affinity to particular food safety hazards. An example would be the high affinity of peanuts to potent fungal toxins such as aflatoxin.
