I would want to finish the MS in food science if you're that close. Can't hurt to have, right? There will always be time to work on the MBA in the future.
		
		
	 
I agree this. 
I was in a similar position to you where I started out with a BEng in Communication and Controls Engineering at UMIST in Manchester, England. The degree was one unit different from and essentially the same as electronics and electrical engineering.  
I decided in the second year that electronics and electrical engineering was not for me and I had to make a decision whether to complete the final year or quit and do something else.
I decided to stick with it and got an Honours degree. I then used this degree as a stepping stone to do a conversion course / Masters in Building Surveying, which is what my current profession is.
I've got my final interview with the Royal Institution of Chartered Surveyors (RICS) to become a Chartered Surveyor on 27/5/10. I'm nervous as hell and I hope I pass (the pass rate is approx. 50%
