I ate a cheeseburger here that gave me an awful asthma attack. I'm sensitive to preservatives used in beef or sausage, and sometimes (about once a year) I do get sick when eating out. However, I've never had an attack while eating at McDonald's in my life. Usually, it's a food preservative at a dine-in restaurant that will set it off an asthma attack.
A week later, I also had an asthma attack eating a McDonald's crispy chicken sandwich in TN. Perhaps they've changed their recipe? Changed food preservatives?
Regardless, I need to give up fast food anyway, it's so bad for you. I don't smoke/live with smokers, and I've never had an asthma attack from food I cooked at home. That's why I think it must be something restaurants use in food as a preservative. This is the first time I've been sick from chicken.
