no. Mcdonalds actually has a near impeccable record of their food being clean. If you get sick from it, it is because you have actual problems. A single batch of onions with salmonella that has hit many companies rarely hits mcdonalds.
and just so you are aware. I am NOT saying mcdonalds is good for you. I am saying their quality standards are very strictly enforced to prevent their company from getting financially hit ironically unlike places that have a higher consumer opinion that can just shrug it off due to having some consumer good will due to their branding and marketing.
