(7) A food handler drops the end of a hose into a mop bucket and turns the water on to fill it. What has the food handler done wrong? A Created a cross -connection B Created an air-gap separation C Prevented backflow D Prevented atmospheric vacuuming

## Step 1<br />The problem presents a situation where a food handler drops the end of a hose into a mop bucket and turns the water on to fill it. This action can lead to a cross-connection.<br /><br />## Step 2<br />A cross-connection is a situation where the potable (drinkable) water supply is connected to a non-potable source. This can lead to contamination of the potable water supply.<br /><br />## Step 3<br />In this case, the hose is dropped into the mop bucket, which is a non-potable source. The water from the hose can mix with the mop bucket's water, leading to a cross-connection.<br /><br />## Step 4<br />The other options, such as creating an air-gap separation, preventing backflow, and preventing atmospheric vacuuming, are not applicable in this situation. The food handler did not create an air-gap separation, prevent backflow, or prevent atmospheric vacuuming.
