KRISPYS KREME SAFE?

So i have really bad OCD and have a hard time differing from what is my OCD talking and what is real. So i went to krispy kreme with my boyfriend and while we were waiting for our donuts i was looking into the kitchen and everything just seemed so unclean and then when we got our donuts and freaked out thinking they could have listeria on them. i had a really bad headache after, and still do. Is that possible? 32 weeks.
