1. Understanding Food Poisoning

Food poisoning is an illness caused by consuming contaminated food. This contamination can occur due to various factors, including improper handling, storage, or cooking of food. Bacteria, viruses, and parasites are the most common culprits behind food poisoning.

1.1. Common Causes of Food Poisoning

Several types of bacteria, viruses, and parasites can lead to food poisoning. Here’s a breakdown of some common causes:

• Salmonella: Often found in raw or undercooked poultry, eggs, and unpasteurized milk. According to the Centers for Disease Control and Prevention (CDC), salmonella causes about 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the United States every year.
• Campylobacter: Frequently found in raw or undercooked poultry and unpasteurized milk. It’s one of the most common bacterial causes of diarrheal illness in the United States.
• E. coli: Some strains of E. coli can cause severe stomach cramps, bloody diarrhea, and vomiting. It’s often linked to raw or undercooked ground beef, unpasteurized milk and juice, and contaminated water.
• Norovirus: A highly contagious virus that causes vomiting and diarrhea. It’s commonly spread through contaminated food, water, and surfaces, as well as direct contact with infected individuals.
• Listeria: Can grow in refrigerated, ready-to-eat foods like deli meats, soft cheeses, and smoked seafood. Pregnant women, newborns, older adults, and people with weakened immune systems are at higher risk.

1.2. How Food Gets Contaminated

Food contamination can happen at any stage of the food production process, from farm to table. Common ways food becomes contaminated include:

• Improper Handling: When food handlers don’t wash their hands properly or use unsanitized equipment, they can transfer germs to food.
• Cross-Contamination: This occurs when raw foods (like poultry or meat) come into contact with cooked foods, spreading harmful bacteria.
• Inadequate Cooking: Cooking food to the right internal temperature is crucial for killing bacteria. Undercooked meat, poultry, and seafood are common causes of food poisoning.
• Improper Storage: Leaving food at room temperature for too long allows bacteria to multiply rapidly. Perishable foods should be refrigerated promptly.
