(CNN) — The Food and Drug Administration has listed on its website more than 3,000 medical facilities across the nation that have received potentially tainted products and urged that patients who received higher-risk products be wary.

Of the facilities identified as having received products from the New England Compounding Center, nearly half (1,279) received medications that the FDA considers at higher risk of causing an infection.

Tainted medications from the compounding center have been blamed for an outbreak of fungal meningitis that has caused 24 deaths and 317 cases of illness.

In a posting late Tuesday, the drug agency urged the facilities to warn patients who may have received the higher-risk products to be alert to the signs of fungal meningitis, which include headache and fever.

The agency said it did not know how many patients may have received the compounding center products in general or how many may have received the high-risk medications.

The listing was posted hours after federal authorities launched a criminal investigation into the company's safety practices.

In addition, the Massachusetts Board of Registration in Pharmacy has voted to revoke permanently the New England Compounding Center's license to operate in the state as well as the licenses of the company's three principal pharmacists.

Those moves were announced in the wake of a damning nine-page report released Tuesday by the pharmacy board, which is part of the state's Department of Public Health.
