A survey on stadium cleanliness was done of all Major League Ballparks. The UFE (Urine/Feces Everywhere) Team, an organization I have never heard of before, visited all 30 Major League Baseball parks to grade each one on cleanliness standards. The UFE Team studied the restrooms, facilities, vendors, and fans, using over 79 different criteria and they rated all 30 Major League Baseball parks. Of all 30 stadiums, the best rating belonged to Busch Stadium in St. Louis. The stadium with the worst rating was Wrigley Field in Chicago.
