Air Force Staff Sgt. James Rodenberg, 386th Expeditionary Medical Group public health technician uses a test strip to test a mix of bleach water which is used to kill microorganisms on food contact surfaces at the main dining facility at The Rock Sept. 23, 2014. If the solution is too weak, it will not kill the microorganisms and if it’s too strong, it can make people sick. Rodenberg conducts inspections two times each month at both dining facilities to promote good personal hygiene across the base and to ensure that facilities are operating in accordance with governing regulations. He deployed from 96th Aerospace Medicine Squadron Eglin Air Force Base, Fla., in support of Operation Enduring Freedom and is a native of Crestview, Fla. (U.S. Air Force photo by Senior Master Sgt.
