Health authorities in Sweden say they\'ve been receiving increasing reports from people in Stockholm who say they\'ve contracted food poisoning from tuna. However, the Swedish Institute for Communicable Disease Control stopped short of issuing a warning to consumers to avoid eating the popular fish, The Local reported Friday. \"Tuna is something that we all eat and there\'s no reason to stop eating it,\" Sofie Ivarsson, an epidemiologist at the agency, said. Distributors and restaurants need to be aware of the issue, she said, as fish can become contaminated during the shipping and preparation process. The increase in reports in Stockholm may be due to the introduction in 2009 of a system allowing city residents to report suspected food poisonings online, Ivarsson said. In 2010, nine out of 10 reports of fish poisoning came from the Swedish capital, The Local reported.
