KANSAS CITY, Mo. (AP) — A food safety manager at Kauffman and Arrowhead stadiums in Kansas City says he was fired after complaining about dirty conditions. Jon Costa shared with ESPN's "Outside the Lines" a letter that he said came from his former employer, Aramark. The March 17 letter said Costa was being fired "for cause" for several reasons, including that he violated the company's media policy by taking his concerns public. ESPN says Costa's complaints prompted a November 3 inspection that found violations at 20 out of 26 food stands. The stadiums later passed a follow-up inspection. Aramark said in a written statement that it considers personnel matters confidential. It added that food safety is "a top priority." Costa's attorney, Ryan McClelland, didn't immediately return phone or email messages from The Associated Press.
