Food poisoning, also known as foodborne illness, arises from consuming food or beverages contaminated with harmful bacteria, viruses, parasites, or toxins. Contamination can occur at any stage of food production, processing, or preparation.
- Bacteria: Common culprits include Salmonella, E. coli, Listeria, and Campylobacter. These bacteria can thrive in raw or undercooked meat, poultry, seafood, eggs, unpasteurized dairy products, and contaminated fruits and vegetables.
- Viruses: Norovirus and hepatitis A are viruses that can contaminate food through infected food handlers or contaminated water sources.
- Parasites: Parasites like Giardia and Cryptosporidium can contaminate food and water, leading to food poisoning.
- Toxins: Certain foods, such as improperly stored seafood or wild mushrooms, can contain natural toxins that cause illness.
2.2. Stomach Virus: A Detailed Explanation
A stomach virus, or viral gastroenteritis, is an infection of the digestive system caused by viruses. These viruses inflame the stomach and intestines, leading to a range of uncomfortable symptoms.
- Norovirus: The most common cause of viral gastroenteritis, norovirus is highly contagious and spreads easily through close contact with infected individuals, contaminated surfaces, or contaminated food and water.
- Rotavirus: Primarily affects infants and young children, rotavirus can cause severe diarrhea and vomiting. Vaccination against rotavirus is available and highly effective in preventing infection.
- Adenovirus: This virus can cause a variety of symptoms, including respiratory illness, conjunctivitis (pinkeye), and gastroenteritis.
- Astrovirus: Similar to rotavirus, astrovirus primarily affects young children, the elderly, and individuals with weakened immune systems.
