Deli meat slicing time: What is the maximum amount of time the slicer can be used before needing to clean and sanitize the equipment?

• A. One hour
• B. Eight hours
• C. Four hours
• D. Twelve hours

Answer: (C)

The main idea is that equipment touching ready-to-eat foods must be cleaned and sanitized regularly to prevent cross-contamination and keep bacterial growth in check. A deli slicer has many food-contact surfaces and can accumulate meat juices that harbor bacteria. Because of that, the slicer should be cleaned and sanitized after four hours of continuous use. If you switch to a different product, or there’s a spill or visible contamination, sanitize sooner. Using the slicer for longer than four hours without cleaning gives bacteria more time to multiply, raising the risk of foodborne illness. The other timeframes either overdo it for routine use or allow unsafe levels of contamination to build up. Four hours is the appropriate maximum.
