An ongoing listeria outbreak tied to Boar's Head deli meat has expanded across five additional states and resulted in a rash of new hospitalizations and deaths, the CDC said in an investigation update on Wednesday.

Since health officials launched an inquiry on July 19, 57 hospitalizations have been reported across 18 states, including nine deaths. An report Wednesday by the CDC reflected a marked increase in the spread since its last report on Aug. 8, which had previously recorded 43 hospitalizations, including three deaths, across 13 states.

Boar's Head has recalled 71 products since July 26, equating to about 7.2 million pounds of deli meats. The brand is also facing legal action, with at least one class-action suit on the books as of early August. The family of one victim, an 88-year-old Holocaust survivor from Virginia, previously spoke to USA TODAY about his death and plans to take legal action.
