The South Korean Food and Drug Administration (KFDA) has published a report claiming that it found bacteria that cause food poisoning in 20% of imported fish. The KFDA examined imported fish between June 2001 and March 2002 and found yellow staphylococcus in 18 out of 89 imported fish, including smoked salmon, tuna, frozen shrimps and frozen octopuses. Other bacteria, including listeria and E. coli were found in three smoked salmon.
