Abstract

Three hundred frozen tilapia fillet samples obtained from shopping malls, supermarkets and conventional markets from different geographical areas of Taiwan in the period July 1997 to June 1998 were screened for parasite and microorganism infections. Results showed that no samples were infected with parasitic metacercaria or larva, nor with Vibrio. However, 0.36% test samples were found to be contaminated with Micrococcus or Aeromonas. The average aerobic bacteria counts for all the test samples were 1.2 × 105 CFU/g; samples obtained from northern, central and southern Taiwan were 7.8 × 104, 1.4 × 105 and 1.5 × 105 CFU/g, respectively, and samples collected from shopping malls, supermarkets and conventional markets were 1.1 × 104, 1.4 × 105 and 1.5 × 105 CFU/g, respectively.
