The proposed bilateral research project with Vietnam deals with studying the microbiological microbiota present on Pangasius hypophthalmus from catch till consumer. It aims at unravelling the contamination routes of specific spoilage organisms (SSO's) during the processing and distribution chain of Pangasius fillets (immediately after capture and during processing in Vietnam, after transport to Flanders, after further processing in Flanders till the end of the shelf life). Special interest goes to the introduction and growth of specific spoilage organisms and the their spoilage metabolism as influenced by different storage conditions.
