A food employee is using disposable gloves while making sushi rolls without interruption. According to California Retail Food Code §113961 and §113973, what is the MAXIMUM continuous time the same pair of gloves may be worn on the same task before they MUST be removed and replaced (assuming no contamination event occurs first)?

Explanation

Under California Retail Food Code HSC §113961 and §113973, single-use gloves must be discarded and replaced (after a handwash) whenever they become soiled or torn, when the employee changes tasks or moves from raw to ready-to-eat food, when an interruption occurs (e.g., touching the face, a phone, money), and at a minimum every FOUR hours of continuous use on the same task. The 4-hour ceiling exists because the warm, moist interior of the glove becomes a culture environment for skin flora (including Staphylococcus aureus) and because micro-perforations accumulate with prolonged use even on the same task. Option A understates the rule (although changing earlier is acceptable best practice). Options C and D dangerously extend the interval; an 8-hour shift wearing the same gloves is non-compliant and unsafe. The glove must always be paired with handwashing — washing gloves themselves is not permitted, and the hand inside the glove must be washed at the handwash sink before donning the new pair.
