It’s possible not too though. I love quorn, always have some around, have eaten it very regularly for years without issue. 

Tried Meati, not the first time but maybe something like the 3rd, same as nifederico, sudden and terrible sickness, passed as soon as it was all out of my system about 2 hell on earth hours later. Never again. 

I know they say to cook to a specific internal temperature, and we didn’t explicitly check ours, so I’ve chosen to believe it was that. Maybe make sure you have a meat or instant read thermometer and use it OP!
