Mould contamination of frozen chicken meat and giblets has a particular public health significance in the field of food safety due to its related food spoilage and production of mycotoxins. The objectives of this study were firstly, to investigate the incidence of mould contamination in frozenchicken meat-cuts and giblets. Secondly, to estimate aflatoxin residues in these products. The public health importance of the prevalent mould genera and aflatoxin residues was discussed. Frozen gizzards had the highest total mould count followed by frozen liver, breast and thigh respectively. The prevalent mould genera were Aspergillus, Penicillium, Cladosporium and alternaria. Aspergillus niger, flavus, parasiticus and versicolor were the identified Aspergilli. Examined frozen chicken samples had variable residual concentrations of total aflatoxins. Thus, strict hygienic precautions during processing of frozen chicken products should be adopted to reduce mould contamination and mycotoxin production.
