Prudent to move medical facility out of food processing plant (5)

Ross

I believe the answer is:

canny

I'm a little stuck... Click here to teach me more about this clue!

'prudent' is the definition.
(I've seen this in another clue)

'move medical facility out of food processing plant' is the wordplay.
I cannot quite see how this works, but
'facility' could be 'can' (synonyms) and 'can' is located in the answer.
The remaining letters 'ny' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'to' acts as a link.

Can you help me to learn more?
