A Chicago food maker agreed to stop making and distributing its sandwiches after the U.S. Food and Drug Administration filed a complaint in federal court describing chronic sanitation problems and Listeria contamination in its processing facility.

Triple A Services signed a consent decree that not only requires the company to halt production, but also to hire a sanitation expert to eliminate Listeria from its plant. 

No illnesses have been reported in connection with the company’s sandwiches, but the government’s complaint describes Triple A’s “history of operating under unsanitary conditions and Listeria monocytogenes in the processing facility,” the FDA said in a news release. The complaint also outlines Triple A’s failure to comply with Current Good Manufacturing Practice and seafood Hazard Analysis and Critical Control Point regulations.

Triple A received warning letters from the FDA on April 20, 2011 and on Nov. 18, 2002 that detail FDA’s critical inspection reports. 

“FDA took these aggressive actions because Triple A Services continued to violate current good manufacturing practice regulations and allow for conditions that could affect the health of consumers,” said Dara Corrigan, the FDA’s associate commissioner for regulatory affairs.
