The Department of Justice, specifically, Prison Farms play a vital role in the prison system, providing work for minimum-security prisoners. The Farms produce food including milk, meat and eggs for the State's prisons. The Farms focus on preparing prisoners for successful re-entry into the community when they are released, giving them job skills linked to agricultural production. The Farms breed cattle and sheep, operate industries for the abattoir, dairy, poultry farm, market gardens and orchards.

The Department of Justice requires the supply and delivery of chicken pullets to the Karnet Prison Farm.  This requirement is for approximately seven 7 deliveries of 650 hens per delivery per year and includes the salmonella vaccination and laying chicken levy.
