What should be our concern when consuming food in an Islamic country? Mostly we don't know the owners of these restraunts and they claim everything is islamicaly slaughtered especially large fast food chains like KFC. Shall we question their integrity or can we take benefit of doubt living in an Islamic country. Also please let us know rulings if we can see that the workers are using gloves and we are not sure of their hands being wet.

Salam the fatwa of all the maraji is that whatever is taken from Muslim markets is deemed halal. You are under no obligation to question it or investigate it
