(June 19, 2008) -- The government's count of people made ill by salmonella-tainted tomatoes has jumped to 383; 106 more than were known earlier this week.

The Centers for Disease Control and Prevention says most of those people got sick weeks ago but just hadn't been counted yet.

Part of this surge results from better testing by states, as well as an end to a backlog of test results in laboratories.

Still, the latest known infected person fell ill on June 5. The CDC's food safety expert says the agency doesn't believe the outbreak is over.
