Chipotle Mexican Grill

I came to Seattle to visit my aunt and ate from a place called chipotle near the university, I am from London , UK.

Just want to ask - do you use lard or pork products in your food?

I do not eat pork or swine products/by products. I am allergic or something. I feel nauseated and feel like wanna throw up. Sorry - if this bothers anyone. But I feel this ONLY when direct pork meat /bone/swine body parts or lard in food.

Please let me know. I was retching. A very rare occurrence because I avoid pork/swine. Thank you.
