Mcdonald's and food poisoning?

I ate at local mcdonalds on feb. 10 and exactly 30 min later I was bedfast with food poisoning .. I had chills, fever and vomiting and stomach pain I cant describe... I recently found out that mcdonald's doesnt refridgerate their dressings and the bigmac sauce is made from eggs and mayo!! I know that is current health food storage violation.. I emailed mcdonalds today on this matter as another member of my family fell victim of the bigmac attack!!! consumers beware of mcdonald's beef and other items.. food poisoning is very BAD
