Tyson closing plants in Chicago and Jefferson, Wis.

Tyson Foods says it’s closing plants in Chicago and Jefferson, Wisconsin, in a move that will affect 880 workers.

Springdale, Arkansas-based Tyson said in a statement Thursday the closures are due to changing product needs, the age of both facilities and prohibitive costs of renovations, as well as the distance of the Chicago plant from its raw material suppliers.

Job losses at the Chicago plant, which makes prepared foods for the hospitality industry, will total around 480 people. Another 400 positions will be lost at the Jefferson plant, which makes sliced pepperoni and ham for pizza toppings, as well as sliced pepperoni and salami for deli and food service applications.

The company expects to close the plants in the second half of its fiscal year, which ends Oct 1, 2016.
