After a power outage, what is the recommended procedure for ice machines?

• A. Discard all ice, wipe down interior surfaces with a dry cloth, and proceed with normal use
• B. Discard all ice, clean with bleach, and run and discard the ice through three cycles
• C. Discard all ice, clean with vinegar, and proceed with normal use
• D. Discard all ice, clean with dish soap, and run and discard the ice through one cycle

Answer: (B)

After a power outage, assume the ice machine may be contaminated and needs a proper clean and sanitize before producing ice again. First, discard all ice to remove any contaminated product. Then sanitize the interior using an approved sanitizer; bleach is acceptable when used according to the manufacturer’s directions, ensuring all interior surfaces are treated. After sanitizing, run and discard ice through several cycles to flush out sanitizer and any remaining contaminants from the water lines. Three cycles provide a thorough purge and help ensure the ice that’s produced next is safe. Using vinegar isn’t an approved sanitizer for food-contact surfaces, and dish soap can leave residues; simply wiping with a dry cloth doesn’t address contamination or sanitizer distribution.
