Chicken liver is rich in iron and vitamin A, but it is also an organ that processes and filters toxins, which is why some studies have found traces of heavy metals and pollutants.
Possible risks:
-
accumulation of toxins and heavy metals;
-
with excessive consumption – risk of hypervitaminosis A;
-
possible presence of bacteria such as salmonella and campylobacter.
Clarification:
Not all chicken liver samples show excessive values - a lot depends on the origin of the meat and the method of heat treatment.
Recommendations:
Consume in moderation, choose chicken from reliable sources, and always cook liver thoroughly.
3. Chicken stomach (muscular stomach)
This part is involved in the digestion of food in birds and may contain residues of bacteria or substances from the feed. If poorly processed, it can become a source of contamination.
Possible risks:
-
presence of bacteria or parasites if not properly cleaned;
-
high cholesterol;
-
possible presence of traces of toxins in birds raised in industrial conditions.
Clarification:
Scientific research on the topic is limited — there is no conclusive evidence that chicken stomachs are dangerous when properly cleaned and cooked.
Recommendations:
Clean thoroughly and cook at high temperature.
4. Chicken feet
Chicken feet are used in soups and broths for their collagen content, but they can contain bacteria, hormones, and environmental contaminants.
Possible risks:
-
antibiotic and hormone residues in birds treated with medication;
-
risk of bacterial contamination (E. coli, Salmonella);
-
possible accumulation of toxins in the skin.
Clarification:
Not all samples show the presence of harmful substances – with good farming control and hygiene , the paws can be safe after full heat treatment.
Recommendations:
Before cooking, peel off the outer layer of skin and cook long enough.
Summary
Chicken remains a valuable source of protein and important nutrients.
The risks associated with certain parts of the bird are not fully proven scientifically , but it is wise to exercise caution, especially with products of unclear origin.
To minimize the risk:
✅ buy meat from reliable farms and organic producers;
✅ cook at a sufficiently high temperature;
✅ avoid or limit parts that are difficult to clean completely.
If you follow these recommendations, chicken can safely be part of your healthy menu.
