Cameroon poultry supply chain shows contamination risks

Research conducted by the University of Yaoundé I and the Institute of Medical Research and Medicinal Plants Studies has identified significant health risks within Cameroon’s poultry supply chain. Studies focused on major poultry production basins in the Centre, Littoral, and West regions revealed the presence of mycotoxins, heavy metals, and veterinary drug residues in poultry feed, chicken tissue, and eggs.

Specific contaminants identified include aflatoxins (such as aflatoxin B1), ochratoxin A, cadmium, lead, mercury, and the antibiotic chloramphenicol. These substances were found in samples of chicken muscle and eggs, often stemming from poorly stored raw materials like maize and peanuts, or the improper use of pesticides, fertilizers, and antibiotics in farming practices.

The contamination affects the entire production chain, from agricultural feed production to commercialization. Because these regions supply major markets in Cameroon and neighboring countries, the findings highlight a broader public health concern for the Central African sub-region.
