I get that currently the cocoa, coffee etc producing nations such as Ghana and Ivory Coast do not currently have Ebola and have closed their borders to immigrant workers from the affected neighbouring countries but in theory if a person who had been infected with Ebola but whose symptoms were not bad enough yet to make them seek medical care (like the nurse who flew into another state and went wedding shopping) handled food products at some stage of the production line or during transit could a another person catch Ebola from that foodstuff because we are led to believe it can be transmitted from any body fluid including sweat or saliva which are easier to have on hands etc than other body fluids without being 'seen'.

Food does not transmit ebola - our stomachs are very good at breaking down the virus.

As David said, injested virus is rapidly broken down (see scholarly reference: http://jid.oxfordjournals.org/content/1 … S142.full)

Additionally, the viral partical is not very stabile outside the body. For this reason, fomites (http://en.wikipedia.org/wiki/Fomite) aren't known to play a role in its transmission. So in the time it would take foodstuffs to be transported out of the country there would not likely be any viable virus left even if it were heavily contaminated.
