Because they're both burritos
Do you expect either lower-quality meat or higher-health-risk meat as a result of this? I don't think I do but maybe I just don't know enough here.
The short warning just read to me as "don't order the pork, you might get sick". Not a great set-up for a good lunch experience. They seem to assume all customers are already educated about their sourcing strategy.

"the CDC reports a total of 55 people infected with the outbreak strain of STEC (Shiga toxin producing E. coli) O26 from a total of 11 states in the larger outbreak"
"Chipotle Mexican Grill closed 43 restaurants in Washington and Oregon in early November 2015 in response to the initial outbreak."
That's very far from rolling the dice with a heath risk.
It should have been framed and explained better.
I personally think that if they can't find meat either they shouldn't sell it (which they did and people got pissed). Or grow your own.
Basically, he's strong in all the areas where Chipotle is perceived of as being weak.
