The number of salmonella cases in Pennsylvania linked to a regional outbreak continues to rise.

The state Department of Health reported in a Pittsburg Post-Gazette article by Christopher Snowbeck yesterday that 260 Pennsylvanians have been sickened in the outbreak thus far — up 50 from Friday. At that time, health officials in West Virginia, Maryland and Ohio were reporting another 73 cases likely tied to the outbreak.

Further tests will determine which of the cases being reported now can be linked definitively to the outbreak. But if the numbers currently reported hold up — and the trend continues for a few more days — the salmonella outbreak could become one of the largest in the nation during the past decade.
