A. Move the container aside and continue working
B. Leave the container alone but work carefully around it to avoid
spilling any product
C. Notify a supervisor immediately

Answers

A I’m pretty sure correct me if I’m wrong:)

It is best to Notify a supervisor immediately ( C ) when you find a container of cleaning product on your food preparation table

When a container of cleaning product is placed close to or on top of a food preparation table without the knowledge of the cook, there is a possibility of food poisoning/contamination, the best action to take is to check for spillage and most likely replace all the raw materials  present on top of the food preparation table but you must first notify the supervisor on duty.

Hence the best action is to Notify a supervisor immediately when you find a container of cleaning product on your food preparation table.
