CDC officials said Thursday, however, that the government shutdown had nothing to do with the timing of their declaration that the outbreak was over. FDA officials said this week that the shutdown is affecting food inspections and that the shutdown is placing the safety of the nation's food supply at risk.
In an email statement, the CDC said it considered the outbreak over because the contaminated romaine shouldn’t be on shelves or in warehouses anymore and there haven’t been new reports of illness since Dec. 4.
