What is Food Poisoning?
- Food poisoning is a foodborne illness caused by consuming contaminated or spoiled food.
- It occurs when harmful pathogens, such as bacteria, viruses, parasites, or toxins, are present in the food.
- Contamination can happen at any stage, from production to preparation and consumption.
- The symptoms of food poisoning can vary but commonly include nausea, vomiting, diarrhea, abdominal pain, and fever.
- The onset of symptoms may occur within a few hours to several days after eating the contaminated food.
- Food poisoning can affect anyone, but certain groups, such as young children, elderly individuals, pregnant women, and people with weakened immune systems, are more susceptible to severe complications.
- Common sources of food poisoning include raw or undercooked meat, poultry, eggs, unpasteurized dairy products, and contaminated fruits and vegetables.
- Proper food handling, storage, and cooking practices are essential in preventing food poisoning and ensuring food safety.
How to Safely Handle and Prepare Food to Prevent Food Poisoning:
- Wash Your Hands: Thoroughly wash your hands with soap and water for at least 20 seconds before and after handling food, especially after touching raw meat, poultry, fish, or eggs.
