- E. coli: Certain strains of E. coli are harmful and can contaminate ground beef, unpasteurized milk, and fresh produce. E. coli infections often lead to severe stomach cramps, bloody diarrhea, and vomiting.
- Listeria: Listeria is a bacterium that can grow in refrigerated, ready-to-eat foods like deli meats, soft cheeses, and smoked seafood. It poses a significant risk to pregnant women, newborns, and individuals with weakened immune systems.
- Norovirus: As one of the most common causes of foodborne illness, norovirus spreads easily through contaminated food, water, and surfaces. It causes symptoms such as nausea, vomiting, diarrhea, and stomach pain, typically appearing within 12 to 48 hours after exposure.
- Campylobacter: This bacterium is often found in raw or undercooked poultry and unpasteurized milk. Campylobacter infections can result in diarrhea (often bloody), abdominal pain, fever, and nausea.
- Staphylococcus aureus: This bacterium produces toxins that can contaminate food, particularly if it’s left at room temperature for too long. Symptoms of Staphylococcus food poisoning include sudden onset of nausea, vomiting, and abdominal cramping.
- Clostridium perfringens: Clostridium perfringens is a bacterium that thrives in cooked foods left at room temperature. It produces a toxin in the digestive tract, causing abdominal cramps and diarrhea.
- Shigella: Shigella is a bacterium that can contaminate food and water, leading to shigellosis, an infection characterized by diarrhea (often bloody), fever, and stomach cramps.
- Hepatitis A: This virus can contaminate food and water, leading to liver inflammation. Symptoms include fatigue, nausea, abdominal pain, jaundice, and dark urine.
- Vibrio: Vibrio bacteria are often found in raw or undercooked seafood, particularly oysters. Infections can cause diarrhea, abdominal cramps, nausea, vomiting, and fever.
Campylobacter thrives in warm climates, often residing in poultry without showing symptoms.
1.2. Vulnerable Foods: Identifying High-Risk Items
Certain foods are more prone to contamination due to their nature and handling processes. Being aware of these high-risk items can significantly reduce your risk of food poisoning:
- Raw or Undercooked Meats and Poultry: These can harbor bacteria like Salmonella and Campylobacter. Cooking meat and poultry to the correct internal temperature is crucial.
- Raw or Undercooked Seafood: Seafood, especially shellfish, can be contaminated with Vibrio bacteria or viruses like norovirus and Hepatitis A.
