Foods contaminated with Bacillus cereus can cause symptoms such as nausea, diarrhea, severe vomiting and excessive fatigue, up to 16 hours after eating.
Main sources of contamination: This microorganism is found in several environments, being identified mainly in agricultural products and animals, so the main sources of contamination with Bacillus cereus come from the consumption of un pasteurized milk, raw meat, as well as fresh or cooked vegetables.vegetables kept at inadequate temperatures.
Symptoms caused by foods contaminated with E.coli vary depending on the type of bacteria found in food, however, the most common include:
Main sources of contamination: Escherichia coli is a bacterium found naturally in the intestine of people and animals and often ingested from faeces, so the main form of E infection.coli is produced by contact with foods contaminated with this bacteria, either through the consumption of uncooked foods, such as uncooked meats or salads, or prepared with poor hygiene.Learn how to properly wash fruits and vegetables.
Diseases caused by pesticide-contaminated foods are mainly cancer, infertility, and other changes in hormone-producing glands, such as the thyroid.
Pesticides are found in small amounts in food and accumulate in the body and therefore, although they usually do not cause disease immediately after eating food, they are involved in the origin of nutrient malabsorption and degenerative diseases, such as some cancers, for example.
When food is contaminated with pesticides or heavy metals, such as mercury or aluminum, it is not possible to see or feel changes, to know if these foods are safe to eat it is necessary to know their origin and know the quality of them.water or land where they were cultivated or raised.
Diseases caused by unhealthy food occur mainly when they expire, in the case of industrialized products, or when the manipulator has not washed his hands or utensils properly.
Although in some cases it is not possible to identify whether the food is damaged, as in the case of a Salmonella infection, in most cases it will have an altered color, smell or taste.
Ingestion of food in poor condition or contaminated with microorganisms causes food poisoning, causing symptoms such as vomiting, diarrhoea and general discomfort that are easily treated simply by hydrating the patient with water, serum and juice.homemade foods, as well as eating light soup and soup, for example.
