Punta Cana is full of food save to eat.
I live here since over 15 years and meats and fruits and veggies offered here all around I never found unsave,
and even without the in foreign countries usual deseases coming up once in a while of foul meet in germany, crazy cows in britain, sick Piggs elsewhere, Birds with a deadly flu etc etc etc.
to find meat, fish, fruits, veggies etc in Punta Cana Bavaro in top quality never been a problem since many long years.
just forget about the typical american costumbre that all is available at the same time under the same roof,
we don't have such trash markets here,
you have to shop around when new in the area, check the different spots,
and after a few weeks you know where you get what kinda product needed and where it is best to buy.
cheers
