Following an investigation into potential criminal violations of federal immigration laws, Mary’s Gone Crackers Inc. will pay $1.5 million and establish a corporate compliance program but will not be prosecuted, the U.S. Department of Justice has announced.

The investigation determined that 48 of the company’s employees were ineligible to work in the United States; Mary’s informed Immigration and Customs Enforcement that the employees had left the company, but further investigation found that Mary’s hired at least 13 of those employees back under different names. In addition to the $1.5-million payment, Mary’s must establish an anonymous tip line for employees to report noncompliance issues, provide I-9 training to employees and report compliance measures to the U.S. Attorney’s Office for two years.
