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.

The infected fish came from China, Norway, India, Thailand and the United Arab Emirates, reported the Korea Herald.

The KDFA used the figures to emphasise the importance of cooking fish properly before eating it, in order to kill the bacteria.
