Two more cooking oil samples have been found to contain a cancer-causing substance at levels higher than the European Union or mainland limit.
The findings come a week after four out of 39 oil samples tested by the Centre for Food Safety were found to have levels of the carcinogenic Benzopyrene exceeding the EU's standard.
The centre said yesterday that one of the latest samples collected from 23 locations contained 14 micrograms of the carcinogen per kilogram, exceeding the mainland's legal limit of 10.
Another, at 3.1 micrograms per kilogram, exceeded the EU's limit of two.
The highest concentration was found in a sample from New World Enterprise (HK). It was from the same batch of a brand of peanut oil that was the source of two of the contaminated samples discovered earlier this month.
The second sample was from distributor Shing Hing Oil Company, for which New World Enterprise is a supplier.
