Assistance of mainland sought
Hong Kong has sought assistance from the mainland's food safety agency to help track down the source of melamine after the industrial chemical was found in one brand of imported eggs.
Animal feed as well as chicken meat will also be tested for melamine in an urgent move prompted by deepening fears of widespread contamination in foods sold in the city.
On Saturday, the Centre for Food Safety found excessive melamine levels in a pack of half a dozen Select Fresh Brown Eggs (extra large) sold by the ParknShop supermarket chain. The eggs were from the supplier Hanwei Group in Dalian in the northeastern mainland province of Liaoning .
Another leading supermarket chain, Wellcome, said it had not sold eggs imported from Dalian.
Secretary for Food and Health York Chow Yat-ngok said: 'We have contacted the mainland's food safety agency and hope they can do more to reduce the risk at the source.'
Dr Chow said the melamine might have come from feed.
