Haagen-Dazs vanilla ice cream from France was taken off the shelves in Hong Kong for the second time in a month after the product was suspected of containing an unauthorised substance. The Centre for Food Safety on Sunday said four batches of the ice cream were found to contain ethylene oxide, a pesticide banned by the European Union. The importer had initiated a recall of the batches in question. “The [centre] urged the public not to consume the affected batches of the products if they have bought any. The trade should also stop using or selling the affected batches of the products concerned immediately if they possess them,” a spokesman said. The batches are Haagen-Dazs vanilla ice cream in mini cup, pint and bulk sizes with best-before dates between July 3 and July 17, 2023. In June, the centre halted the sale of two batches of the same product, after the pesticide was found by its Taiwanese counterpart. In a reply to the Post , Haagen-Dazs Hong Kong said the French headquarters had investigated its production line following the June incident and found that the vanilla extract from one supplier was the source of the banned substance.
