Answer:
Put the item in a new pouch in the packaging area and resterilize
Step-by-step explanation:
If an object has been sterilized it is completely without any microorganism in it. That is, this object is clean, but that does not mean that it is immune to contamination by microorganism, this contamination will happen when this sterilized object comes into contact with a contaminating environment, in which case the object must be resterilized.
An example of this can be seen in the question above, where a paper-plastic peel pouch that was sterilized fell to the floor. The floor is a highly contaminated environment, so the bag has become contaminated and should be resterilized.
