Input: Two samples showed "very high" readings for E. coli, and another had a "very high" reading for bacillus cereus, both of which can cause diarrhoea. Food hygiene experts are set to recommend banning three stalls from future carnivals. The event's organisers Notting Hill Carnival Limited declined to comment. One million people attended the two-day festival this year, which featured 283 licensed food sellers. Council inspectors visited 250 stalls and gave out 44 warnings, down on the previous year's 71. Inspectors took samples from seven stalls which had poor food hygiene and sent them for microbiological tests, according to a report for a Kensington and Chelsea council's scrutiny committee, the Local Democracy Reporting Service said. They said six results which came back from showed unsatisfactory hygiene, the report said. The results were a "deterioration on previous years", according to a second report to the committee. Inspectors recommend that the three stalls with the worst results should be turned down if they want to trade at future carnivals. The council, which funds and regulates the event, said it had a "large team [...] dedicated to making sure the food served over the weekend is stored, prepared and served the right way". How dangerous are E. coli and bacillus cereus?
