More than 20 people have died and about 300 have been sickened by fungal meningitis linked to NECC steroid injections.
Congress, now in recess, has been pushing for action on the outbreak for weeks.
The spate of illnesses has put focus on compounding pharmacies, which reprocess drugs on a large scale to fit patients' needs and are not obligated to follow many rules that apply to drug makers.

"This company may have disregarded federal guidelines, and we need to know from [regulators] whether the company misled regulatory authorities and if sanctions against the company are available or warranted," said Markey, whose district houses the Framingham-based company.
Markey has promised a bill that will enable greater oversight of compounding pharmacies. Rep. Rosa DeLauro (D-Conn.) has introduced a similar measure, and Sen.

The outbreak has also prompted criticism of the Food and Drug Administration (FDA), which lawmakers claim failed to follow up with the NECC after past inspections prompted worries that the company's practices were unsafe.
Some of the NECC's violations directly foreshadowed the contamination of steroid injections linked to the current cases of meningitis, lawmakers wrote Monday.
"On December 4, 2006, the FDA sent the NECC a warning letter detailing significant violations of the Food, Drug and Cosmetic Act witnessed by the investigators," lawmakers wrote to an NECC lawyer, Paul Cirel.
"Included in the list of violations was the NECC's manipulation of a sterile injectable product, which caused the FDA to be 'especially concerned about potential microbial contamination,' " the leaders wrote.
The NECC has recalled all of its products and surrendered its state license in response to the outbreak, which has put an estimated 14,000 people at risk.
Monday's letter was signed by Energy and Commerce Committee Chairman Fred Upton (R-Mich.) and ranking member Henry Waxman (D-Calif.).
