Food poisoning, also known as foodborne illness, is a common illness caused by consuming contaminated food or drinks. These contaminants can include harmful bacteria, viruses, parasites, or toxins produced by these microorganisms.
Food poisoning symptoms often manifest as gastrointestinal distress, including nausea, vomiting, diarrhea, and stomach cramps. The severity and duration of symptoms can vary depending on the type of contaminant and the individual’s overall health. Most cases resolve within a few days without medical intervention. However, severe cases can lead to hospitalization and even death.

While most individuals recover fully from food poisoning, certain groups are at higher risk of developing severe complications. These include infants, young children, pregnant women, older adults, and individuals with weakened immune systems. For these vulnerable populations, food poisoning can be life-threatening.
Contamination can occur at any point in the food production and preparation process, from farm to table. Common sources of contamination include improper handwashing, cross-contamination from raw to cooked foods, inadequate cooking temperatures, and improper food storage.

Various bacteria, viruses, and parasites can cause food poisoning. Some common culprits include Salmonella, E. coli, Campylobacter, Norovirus, and Listeria. Each pathogen has a specific incubation period and associated symptoms. For instance, Salmonella infection typically manifests within 6 to 72 hours after consuming contaminated food, causing diarrhea, fever, and abdominal cramps.
Preventing food poisoning involves practicing safe food handling techniques. These include washing hands thoroughly, cooking food to safe internal temperatures, refrigerating perishable foods promptly, avoiding cross-contamination, and consuming only pasteurized dairy products.
