A ParknShop supermarket manager has been given hygiene lessons after a complaint about the shop selling re-frozen and damaged food. As a result of teacher Pauline Bunce's complaint, the manager of the Heng Fa Chuen store in Shing Tai Road was given food safety lessons by food and environmental hygiene officers. Ms Bunce claimed cartons of frozen food, including meat and fish products, had shown obvious signs of being thawed and then refrozen, posing a health hazard. 'Not one of the store staff I've spoken to so far understands the risks that I've referred to,' she said, adding that she had also been forced to pull out rows of canned food before finding some without a dent. Checks by health inspectors at the store late last week failed to find any problems with the store's frozen meat. But a ParknShop spokesman admitted there had been a problem with the main freezer and it still required daily maintenance. The inspectors found some of the store's canned products failed to meet health standards. A department spokesman said: 'Health education on food hygiene, including proper storage, handling and transportation of chilled and frozen meat was given to the senior manager of the shop. Necessary health advice was also given on frequent stock-checking and rotation.'
