Final answer:
Dirty mop water from a food establishment should be disposed of in a designated mop sink to maintain cleanliness and safety.
Step-by-step explanation:
When it comes to disposing of dirty mop water from a food establishment, it is important to follow proper protocols to ensure safety and hygiene. The correct option would be b. Dispose of it in a designated mop sink.
It is crucial to avoid pouring dirty mop water down the kitchen sink (option a) as it can contaminate the water supply and create potential health hazards. Dumping it in an outdoor trash bin (option c) is also not appropriate, as this can lead to the spread of germs and foul odors. Leaving it in the mop bucket for the next use (option d) is unsanitary, as it can promote the growth of bacteria and other pathogens.
By disposing of the dirty mop water in a designated mop sink, it can be properly handled, drained, and cleaned, ensuring the maintenance of a clean and safe environment in the food establishment.
