KASSON — A grain dust explosion and fire have damaged part of a grain elevator in southeastern Minnesota, but no one was hurt.

A Dodge County sheriff’s dispatcher says the blast was reported at Kasson’s Greenway Co-op just before 2 p.m. Thursday.

Co-op general manager Tim Clemens said that damage from the fire is expected to be minimal.

The explosion happened in a “leg” that lifts corn. The leg is about 60 feet tall.

Firefighters from Kasson and Dodge Center responded.

The grain elevator was the focus of a $5.5 million expansion last year. Repairs are expected to be made in a day or two.
