Food safety – Food is generally free of parasitic or bacterial contamination, but be prudent anyway. Look at where local people are preferring to eat. Do not eat stuff that is sold outdoors, at least in summer and at least which local folk don’t eat. They can spoil fairly quickly without needed refrigeration. Wash thoroughly and/or peel fresh fruits and vegetables. They may be free of biological contaminants but their skin is probably heavily loaded with pesticides (unless you see the not-very-common certified organic produce marker on, of course). Food in western regions of the country is OK for (western) travellers for the most part, but the more east, south, and northeast you go, the more unaccustomed contents in the food you’ll come across, like goat or goose meat or hot/heavy spices. These contents may or may not cause diarrhea, but it is wise to have at least some anti-diarrhea medicine nearby, especially if you are going to travel to places a bit off-beaten-track.
