The child labor trial of a former Iowa kosher slaughterhouse manager accused of exposing children to dangerous chemicals and working them for too many hours is to start Monday.

A jury was selected last week to hear the case against former Agriprocessors manager Sholom Rubashkin in Black Hawk County
District Court in Waterloo.

Rubashkin faces 83 charges. The charges were condensed from thousands of counts and charges were dropped against two
co-defendants, including Rubashkin's father.

In a separate case, Rubashkin was convicted of 86 federal financial fraud charges in November. Sentencing in that case is May 27.

Agriprocessors was the site of a 2008 raid in which 389 workers were arrested on immigration charges.
