What is microbiological analysis?

Microbiological analysis covers the use of biological, biochemical or chemical methods for the detection, identification or enumeration of microorganisms. It is often applied to disease causing and spoilage microorganisms.

Why is microbiological analysis important for the monitoring of food products?

In suspected outbreaks, microbiological testing is important both to identify foods that are more likely to be associated with disease and to pinpoint areas where controls have broken down. This allows future work to concentrate on areas that will have the greatest impact on safety.

How do you carry out microbiological analysis?

An easier and more accurate method to determine the microbial count is the plate method, where a food sample is placed on a culture medium plate. After an appropriate incubation period, you can count the number of colonies that have formed on the culture medium plate.

What is microbiological Criteria for Foods?

A microbiological criterion for food defines the acceptability of a product or a food lot, based on the absence or presence, or number of microorganisms including parasites, and/or quantity of their toxins/metabolites, per unit(s) of mass, volume, area or lot.

What is the relevance of microbiological standards for food safety?

Microbiological criteria give guidance on the acceptability of foodstuffs and their manufacturing processes. Preventative actions, such as the application of Good Hygiene and Manufacturing Practices (GHP, GMP) and the Hazard Analysis Critical Control Point (HACCP) principles contribute to achieving food safety.

What are microbiological parameters?

Microbiological parameters should assess bacterial density, as well as the presence of mucoid morphotypes and strains that are multi-resistant or have a high capacity for transmission [68,98]. From: Clinical Microbiology and Infection, 2005.

What is the importance of food microbiology?

Food microbiology is important because microbes and food interact in both positive and negative ways. They can make or be the food, enhance it, spoil it, or make it unsafe to eat. Knowing how to bring out the good and prevent the bad is very important since people need to eat.

What is microbial analysis?

Microbiological analysis provides the characterization of micro-organisms on or in a medical device, package, raw material or component. Testing the microbiological makeup of a product allows manufacturers to ensure that there are no bacteria or toxins that may harm the user.

What is the role of a food microbiologist?

The primary role of a food microbiologist is identifying and determining the quantity of food-borne microorganisms. A food microbiologist can work in various sectors and environments.

What are microbial foods?

Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs.
