It may seem that advances in technology, chemistry and biology free us from any risk when consuming food, water and cosmetics, but the improvement on these fields goes hand in hand with the appearance of new pathogens and other threats to the optimal quality for human consumption.
Purposes of a microbiological analysis
The main purpose of this type of study is to determine whether there is any risk to animal or human health, and to determine what the elements that expose that food to contamination are in order to avoid them.
Components of a microbiological analysis
- Sampling
- Analytic Method
- Result interpretation
Common diseases that it can prevent
Most diseases that food can cause are related to diarrhoea. While it is true that in a healthy, well-fed person the impact is lower, these types of diseases can be damaging to their health.
- Salmonellosis. Caused by the Salmonella sp. bacteria which is transmitted through direct contact or cross-contamination during food handling.
- Staphylococcosis or staphylococcal food poisoning. Caused by the golden staph (Staphylococcus aureus). A bacteria that is commonly found in mucosae and can cause cutaneous infections, gastrointestinal diseases, and even some other diseases such as meningitis or endocarditis.
- Necrotic enteritis or gas gangrene (Clostridium perfringens). The bacteria that causes this disease is found in the intestines of several humans and animals, and can cause the destruction of affected tissues. Even though there are highly effective treatments to combat it, it can be lethal.
- Gastroenteritis. Highly common, but equally important, gastroenteritis is an inflammation of the intestine that can be caused by viruses (Rotavirus, Norovirus) or bacteria (Vibrio parahaemolyticus, Campylobacter spp., etc.), whose transmission may result from the consumption of food handled in poor hygienic-sanitary conditions or from contaminated waters.
