Your bag can always be x-rayed, its usually a random selection if they are actually operating it.
One time flying from SBH back home via SXM they x-rayed my bag which had the Veuve Clicquot St Barth special tin and made me open to show the bottle, plus wanted to the know price.
I wonder if you are actually bringing $100's of food would they make you pay a duty?
