In particular trimming is considered a high-risk step of Accepted March 29 2021 cross-contamination during processing. This study aimed to compare and evaluate the microbial quality at trimming step in four frozen Pangasius Keywords processing factories located in the Mekong Delta region. Trimmed Pangasius fillet and contact surfaces samples . gloves and processing Hygiene tools were examined including total mesophilic counts Coliforms E. coli and coagulase-positive Staphylococci Staphylococci coa . The results Microorganisms showed that total mesophilic counts on trimming Pangasius processed in A B C and D plant were and Pangasius Quality log CFU g respectively. Coliforms E. coli and Staphylococci coa on Trimming trimmed Pangasius ranged - - and - log CFU g respectively. Thus proper preservation of fillets during processing is Corresponding author suggested. Good manufacturing practices should implement effectively to minimize the risk of cross-contamination for the trimmed fillets. Tong Thi Anh Ngoc Email ttangoc@ Cited as Nguyen T. C. Nhan H. T. M.
