The Wichita Falls ISD has implemented new cleaning procedures for locker rooms after three student athletes at Rider High School tested positive for staph infection in early September. Ashley Thomas, communications officer for the district, said the district learned of the positive test results on Sept. 8. The following day, the Wichita Falls-Wichita County Public Health District was asked to collect swab samples. … Lou Kreidler, director of health at the health district, said employees from the General Environmental office met with Aramark and discussed their cleaning procedures. She said it came down to the cleaning company simply not cleaning appropriately.
