HARRISBURG — Pennsylvania health officials have confirmed a fifth case of salmonella linked to a national outbreak involving tainted tomatoes.

State Health Department spokeswoman Stacy Kriedeman said Thursday the latest case involves a victim from Montgomery County who fell ill in early June.

The department had previously announced that four other people were sickened in late May in Bucks, Butler, Lancaster and Warren counties.

Officials believe two of those victims were exposed outside of Pennsylvania.

Kriedeman said the department can't release details about the victims or how sick they were, but she says the onset of salmonella typically occurs 24 to 72 hours after exposure and victims usually recover in five to seven days.

About 2,000 cases of salmonella are reported in Pennsylvania each year.
