Food poisoning, also known as foodborne illness, occurs when you consume food contaminated with harmful bacteria, viruses, parasites, or toxins. Let’s dive deeper into what causes it and how to recognize the symptoms.
1.1. What Causes Food Poisoning?
Food poisoning can stem from various sources, each introducing different pathogens or toxins into your system. Some common culprits include:
- Bacteria: Salmonella, E. coli, Listeria, and Campylobacter are among the most frequent bacterial offenders. These bacteria can contaminate food at various stages of production and preparation. According to the Centers for Disease Control and Prevention (CDC), Salmonella causes the most food poisoning cases in the United States.
- Viruses: Norovirus is a leading cause of food poisoning, often spreading through contaminated food handlers or surfaces. Hepatitis A is another viral threat that can be transmitted via contaminated food. The World Health Organization (WHO) notes that norovirus is responsible for a significant number of gastroenteritis cases worldwide.
- Parasites: Parasitic infections like Giardia and Cryptosporidium can result from consuming contaminated water or undercooked food. These parasites can cause prolonged gastrointestinal issues.
- Toxins: Certain foods, like improperly stored seafood, can contain natural toxins that lead to food poisoning. For example, scombrotoxin poisoning occurs from consuming fish that hasn’t been correctly refrigerated, leading to high histamine levels.
