THE Lufthansa in-flight caterer is being sued for allegedly providing inferior meals - including one said to have contained a cockroach - to schools in Hong Kong. Nutritional Food Production Ltd alleges the meals and services supplied by LSG Lufthansa Service Hong Kong were of 'substandard or unacceptable quality'. A writ was filed in the High Court yesterday. LSG, one of three in-flight caterers operating from Chek Lap Kok, has a worldwide catering network. The two companies entered into agreement for LSG to supply pre-cooked meals as boxed lunches for various primary and secondary schools in Hong Kong, the writ says. After the service began on August 31, following a satisfactory survey, 'the defendant continuously supplied meals and services of substandard and unacceptable quality to the plaintiff, despite repeated complaints', the writ says. The meals were of 'unacceptably small and uneven portions' and the standard of the food did not correspond to the samples given in the survey, the writ says. As a result of the alleged breach of agreement, it claims, Nutritional Food Production suffered a 'substantial decrease in orders placed by their customers'. The company suffered an $11,164,500 drop in gross annual turnover and loss of goodwill, the writ says. The firm is claiming $3,349,350 in estimated lost gross profits and an unspecified amount in damages.
