There are Mars Inc (maker of Starbursts) factories around the country. Starbursts are made in Topeka, Kansas.
This local plant employs between 300 and 600 people, depending on the time of the year and production demands. It opened in 1978, becoming the first Mars plant to operate west of the Mississippi River, and its first candy product was Starburst, a fruit-flavored soft confection.
