Foodborne Illness from Contamination
Raw poultry is a common carrier of pathogenic bacteria, which can lead to foodborne illness, or food poisoning, if not handled and cooked properly. The most significant culprits are Salmonella and Campylobacter, which can contaminate poultry during the slaughtering and processing stages.
Key Pathogens: Salmonella and Campylobacter
- Salmonella: This bacterium causes an infection known as salmonellosis. It can lead to symptoms such as diarrhea, fever, stomach cramps, and vomiting, typically appearing within 8 to 72 hours of exposure. While most healthy individuals recover within a week, the infection can be more severe in children, older adults, and those with weakened immune systems, potentially leading to hospitalization.
- Campylobacter: A leading cause of bacterial foodborne illness worldwide, Campylobacter can cause campylobacteriosis, with symptoms like diarrhea (sometimes bloody), abdominal pain, and fever. It is a particular concern as some strains can lead to rare but serious long-term complications, such as irritable bowel syndrome or Guillain-Barré syndrome, a neurological disorder causing muscle weakness.
The Dangers of Undercooked Chicken
Thorough cooking is the most effective way to kill harmful bacteria present in poultry. When chicken is undercooked, it can still harbor live pathogens, which are then ingested. The safe internal temperature for all poultry is 165°F (75°C), which should be measured with a food thermometer inserted into the thickest part of the meat. A visual check is not always enough, as juices can run clear even if the meat is not fully cooked.
Risk of Cross-Contamination
Cross-contamination is a major risk when handling raw poultry. Bacteria can spread easily from the raw chicken and its juices to other foods, utensils, and surfaces. For example, placing cooked food on a plate that previously held raw chicken can transfer bacteria. A USDA study revealed that even after cleaning, germs can persist in the sink area where chicken was washed. It is strongly recommended not to wash raw chicken to avoid splashing bacteria around the kitchen.
To prevent cross-contamination:
- Use a separate cutting board and knife for raw poultry.
- Wash hands thoroughly with soap and water for at least 20 seconds after handling raw chicken.
- Store raw chicken on the lowest shelf of the refrigerator, in a sealed container or plastic bag, to prevent juices from dripping onto other foods.
Hidden Risks Beyond Food Poisoning
Beyond immediate foodborne illness, other long-term side effects and health concerns are associated with poultry consumption, particularly with industrialized farming practices.
The Problem of Antibiotic Resistance
The widespread use of antibiotics in large-scale poultry farming for growth promotion and disease prevention is a significant contributor to the rise of antibiotic-resistant bacteria. These resistant bacteria can be transferred to humans through the food chain, making it harder to treat human infections. This poses a serious public health threat and can make common antibiotics less effective.
High Cholesterol and Saturated Fat
While often marketed as a healthier alternative to red meat, certain cuts and cooking methods of chicken can contribute to high cholesterol and saturated fat intake. A study published in the American Journal of Clinical Nutrition found that consuming high levels of white meat, like chicken, can increase LDL ("bad") cholesterol levels in a way similar to red meat. Skin-on and deep-fried preparations are particularly high in fat. Opting for skinless cuts and healthier cooking methods is key for heart health.
Unhealthy Additives in Processed Poultry
Processed poultry products, such as chicken nuggets, tenders, and lunch meats, can contain a high amount of sodium, preservatives, and other unhealthy additives. Some preservatives, like nitrites, can form carcinogenic compounds. Processed meats, in general, are linked to an increased risk of heart disease and type 2 diabetes.
Making Healthier Choices: A Comparison
| Factor | Healthy Preparation | Less Healthy Preparation |
|---|---|---|
| Cut | Skinless breast, thighs, or drumsticks. | Processed chicken products (nuggets, tenders), ground chicken with skin. |
| Preparation | Grilled, baked, roasted, steamed, or stir-fried. | Deep-fried, heavily processed, or cooked in excessive oil. |
| Saturated Fat | Lower fat content, especially if skin is removed. | Higher saturated fat content due to added oils and skin. |
| Additives | Minimal to no added chemicals or preservatives. | Often contains nitrates, nitrites, and high levels of sodium. |
| Overall Health | Lean protein source beneficial for muscle growth and weight management. | Contributes to higher calorie, fat, and sodium intake, and associated risks like increased cholesterol. |
Safe Handling and Preparation Practices
Adhering to strict food safety guidelines is the most effective way to enjoy poultry with minimized risk. Following these steps can prevent foodborne illness and cross-contamination:
- Handwashing: Always wash your hands with soap and water for at least 20 seconds before and after handling raw poultry.
- Separate Utensils: Use dedicated cutting boards, knives, and dishes for raw poultry to prevent cross-contamination with ready-to-eat foods.
- Proper Storage: Store raw chicken on the bottom shelf of your refrigerator to prevent juices from leaking onto other food items.
- No Washing: Do not wash raw chicken before cooking, as this practice can spread harmful bacteria around your kitchen.
- Cook Thoroughly: Always cook chicken to a minimum internal temperature of 165°F (75°C), checking with a food thermometer. The juices should run clear.
- Refrigerate Promptly: Refrigerate any cooked chicken leftovers within two hours to prevent bacterial growth.

Conclusion
While poultry chicken is a popular and nutritious source of protein, it is not without potential risks. The most common side effects are linked to foodborne illnesses from bacteria like Salmonella and Campylobacter, which can be effectively prevented through diligent food safety practices like proper cooking and handling. Additional concerns include the rise of antibiotic-resistant bacteria due to industrial farming and elevated cholesterol from high-fat cuts or preparation methods. By being mindful of these factors and making informed choices about the type of chicken consumed and how it is prepared, individuals can minimize the negative side effects and continue to enjoy poultry as part of a balanced and healthy diet.
