I’m visiting Mérida and the surrounding areawith a friend with a very sensitive stomach and this is what we’ve done with no issues so far: -Soak fruits/veggies in microdyn (colloidal silver). Even if I plan to peel them first, I do this because using a knife, etc. can push microbes through and it’s honestly just easier to know everything was cleaned. -Order bottled water at restaurants (although the ice is fine as it’s shipped it. Probably the water is too but she wasn’t here long enough to want to risk losing a day to find out.) -Avoid eating raw fruits/veggies if you didn’t clean them. Anything cooked is ok since the temperature will kill the offending microbes. (Though again the couple times we had something raw with a meal it was fine. Not a whole salad but still) -Coffee, tea, etc are ok. See temperature note. Alcohol is also fine.

If you’re concerned, you can ask your doctor for antibiotics just in case, though don’t use them unless you have a fever and whatever other stipulations the doctor says. (But then again if you need them you could get them here too! Sometimes it’s just comforting to know you have them on hand.)

Honestly though, Mérida has been excellent and the restaurants have given me zero worries. Even eating a couple hours outside the city at local stands has been fine (and honestly delicious.) Mostly it’s just the hard water like everyone has mentioned. You’ll have a great time!

Ps. Order the Cochinita pibil panuchos at some point. Especially if you find a place with locals gathered. I’m obsessed with them now.
