(locally called in Western Nigeria) is a table fish. During processing like poaching and smoking, fish come in contact with water, smoke and high temperatures, which may interfere with the nutrient contents and are potential sources of reactive di-carbonyl compounds (RDCs) and polyaromatic hydrocarbons (PAHs). This study was therefore conducted to determine the level of RDCs and PAHs in raw and processed fillet; skin, head and bones (SHB). Fish samples were prepared by poaching and smoking (charcoal and wood). RDCs and levels of 5 individual PAHs including fluorene, phenanthrene, anthracene, benz(a)anthracene and naphthalene were determined in raw, poached and smoked (charcoal and wood) using standard methods. Results indicated that all processing methods significantly increased ( < 0.05) levels of RDCs and PAHs in the fillet and SHB. In conclusion, the study demonstrated that charcoal smoke processing produced the lowest levels of RDCs and PAHs in fillet and SHB.
