dc.description.abstract |
Problems with the safety and shelf life of export hake have been raised by the Namibian fishing
industry. This prompted an investigation into the factors that may have an impact on the
microbiological quality and safety of processed hake. Samples were collected along the processing
line; the general microbiological quality (mesophylic and psychrotrophic aerobic plate counts), total Vibrio species and common fish spoilage bacterial counts were performed. The results constantly showed relatively high counts for the psychrotrophic and spoilage bacteria, indicating that most of these bacteria already formed part of the incoming fish. Hake is headed and gutted on board of fishing vessels and delivered to the factory only after 7 – 8 days for final processing. It is likely that this
practise of heading and gutting the hake may have a negative effect on microbiological quality of the final product. A sharp increase in the mesophilic and sucrose fermenting Vibrio species counts were observed after filleting. It has been suggested that this contamination could be due to biofilms present in the distribution system for the treated sea-water used during processing. Although, sea-water could be an alternative source of water for marine fish processing plants, the treatment and the quality of the
water needs to be carefully managed. |
