The Swedish authorities have withdrawn some six tonnes of Dutch hamburger and kebab meat from sale after finding the potentially lethal EHEC bacteria in samples, news agency ANP reports on Monday.
Swedish media say Dutch meat is to blame but it is unclear which Dutch company supplied the products. The investigation began in January after two children became ill after eating hamburgers.
According to ANP, the meat was already on the market when the contamination was found, and at least half of it had been sold. This means some 60,000 hamburgers containing the bacteria could be in circulation.
