Updated at 6.04pm: Tests results of eel samples to detect the pesticide endosulfan were satisfactory, the Food and Environmental Hygiene Department (FEHD) said on Wednesday.
The six eel samples were collected for tests after endosulfan was detected in live eels in Japan last week.
Endosulfan is mainly used on fruit and vegetables and is monitored under the food surveillance programme of the department?s Centre for Food Safety (CFS).
A spokesman for the centre said on Wednesday no endosulfan was detected in four of the samples. This included two live eels and two eel products.
Only a trace amount of the pesticide was found in two live eel samples, each at about 0.02 ppm.
The spokesman said this might be due to environmental contamination and would not pose any health risks.
