Objective:
To investigate the status of bacterial contamination in the shellfish products in Wenzhou.
Methods:
One hundred samples were collected and their bacterial populations including the total plate count were investigated.
Results:
Of the 100 samples collected, 67 samples failed to not meet the national regulations due to bacterial contamination, accounting for 67% of the total samples. Among the contaminated samples, the most serious contamination was caused by coliforms (61.4% of the total plate count with contamination), followed by Salmonella (18.6%), Vibio parahaemolyticus (15.7%), Listeria spp. (4.3%) and others (6%).
Conclusion:
Microbial pollution has become a threat to the marine shellfish products in Wenzhou.
