Have any of you mongers gotten the shits from your visits to TJ. I haven't been to Mexico in about 50 years but it used to be a Major concern to me. I did get it twice. Once in Ensenada south of TJ and once in Acapulco.
My rules became no street vendors and no uncooked foods like salads. I took my chances with ice cubes in my drinks but mostly stayed with bottled drinks.


Never had a problem, and I've been maybe a dozen times in the past 3 years. The only precaution I take is not drinking tap water and not brushing my teeth etc. Regarding ice, I just trust whomever is serving it used purified water to make it.
And I definitely indulge in street vendors - the tacos at the corner of Av. Niños Héroes and Calle Coahuila are absolutely outstanding.
FWIW, I think Mexico 50 years ago is vastly different than it is today. Tijuana, outside of the grittyness of the Zone of Tolerance, is a thriving and hip metropolitan area with lots of commerce and nightlife. I think 50 years ago most of the city probably didn't exist.
I was just in CDMX, and I was almost envious of their infrastructure, much of it new.
