Gov. Jay Nixon has replaced the director of the Missouri Department of Agriculture.
Nixon announced Friday that department director Jon Hagler had been replaced effective immediately.
The governor's announcement offered no explanation. But the change comes one day after the department's associate director for meat and poultry inspection distributed a letter saying she was resigning because of a hostile and disrespectful work environment.
Spokespeople for Nixon and the Agriculture Department did not return messages seeking further comment Friday.
