what food will definitely run out cause of "this volcano"?

i remember during the "petrol crisis", when i was working at sainsburys: people were going round the place like it was supermarket sweep, piling up trolleys with loaves of bread and pint upon pint of milk. some people at work suggested we might run out of these (none of which are on my weekly shop) due to "this volcano":

bananas
kiwi fruits
passion fruits

what else? i like a bit of a panic of these things.
