BOSTON (CBS) – The compounding pharmacy in Framingham blamed for a national fungal meningitis outbreak reportedly sent customers a “quality assurance report card” just before people started getting sick.

According to the Boston Globe, the New England Compounding Center boasted about the cleanliness of its labs, saying there were no instances of contamination beyond the accepted standard in the first half of the year.

But at the same time, the center’s own internal testing found that 33 surface samples from its clean rooms contained high levels of bacteria or mold.

Nationwide, 28 deaths have been linked to tainted injectable steroids from the lab, which is now closed.
