The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department on September 30 released its food safety report for August 2026, finding about 6,000 tested food samples had an overall satisfactory rate of 99.8 per cent, apart from 13 unsatisfactory samples announced earlier.

About 1,700 samples underwent microbiological tests and about 4,300 chemical and radiation level tests, the CFS said. The unsatisfactory samples included an orange, two choi sum samples, a pak-choi sample and a watermelon sample with pesticide residue exceeding the legal limit; fresh beef containing sulphur dioxide; an imported prepackaged black cod steak with methylmercury above the legal limit; four prepackaged milk samples with colony counts exceeding the limit; imported prepackaged rice vermicelli with a trace amount of formaldehyde; and bottled pistachio paste with an excessive amount of aflatoxin. The CFS said it informed vendors, instructed them to stop selling the affected items and traced their sources.

The CFS also said it would continue enhanced testing of imported Japanese food following Japan's discharge of treated water from the Fukushima nuclear power station, publishing radiological test results on working days on its dedicated webpage.
