State health officials say an elderly Montgomery County woman is the first person in Pennsylvania with a confirmed case of Listeriosis from eating tainted cantaloupe. The woman, from the Collegeville area, became sick in September and has since recovered.  She did not have any tainted cantaloupe in her home, but she had recently traveled out-of-state, and she may have eaten it somewhere else.  Melons from Jensen Farms in Colorado have been linked to 23 deaths and 116 illnesses in 25 states.
