Slaughterhouse cleaning firm accused of using stolen identities and employing minors.

Workers for Packers Sanitation Services Inc. (PSSI), a company that sanitizes more than 400 slaughterhouses and other facilities during overnight shifts, have repeatedly used stolen identities to get hired, according to former company managers, local police officials, and individuals who told NBC News their identities were stolen. The company recently paid a $1.5 million fine and agreed to three years of increased oversight after investigators uncovered children as young as 13 working dangerous jobs in 13 locations in eight states. PSSI employs 17,000 workers nationwide, and working conditions are hazardous.
