It has been four months since the salmonella outbreak from a science project at Jefferson Elementary and some parents are dissatisfied with the school’s slow response.

"That’s the most important thing,” said Jessica Medeiros, a parent of one of more than four dozen students who contracted salmonella after participating in a science dissection experiment in June.

Jefferson students were the only ones who were affected by the disease after dissecting owl pellets, and some parents there say they still have unanswered questions about how quickly and completely school officials identified and responded to the outbreak.

“I think a new policy or set of procedures should have been dealt with before school started this fall,” said Medeiros.
