Master Sgt. John Kortes, 451st Air Expeditionary Wing Public Health inspector, checks a testing strip after dipping it in the food facility's sanitizing bucket during a monthly inspection at Kandahar Airfield's boardwalk Nov. 14. The testing strips are used to ensure the bucket's chlorine concentration is high enough to properly sanitize food-contact surfaces.
