The city council of Birmingham, England, is prosecuting candy and beverage company Cadbury Schweppes for manufacturing and selling chocolate contaminated with salmonella bacteria last year. The company recalled more than one million chocolate bars, but did not inform authorities of the problem until five months after discovering it. Dozens of people got food poisoning, and the bad publicity cost Cadbury Schweppes £10 million. The problem was caused by a pipe that carried waste water from cleaning machinery and leaked into machinery making the chocolate. When recalling the chocolate bars, the company announced that the risk of sickness was low, but the BBC quoted a bacteriologist saying that there are no safe levels of salmonella in chocolate.
