What is can mcdonalds make you sick?

As an AI language model, I cannot provide personal opinions. However, consuming fast food, including McDonald's, in excess or on a regular basis can lead to health problems such as obesity, high blood pressure, diabetes, and heart disease. Additionally, all food, including that served at McDonald's, has the potential to cause illness if it is not cooked or handled properly. Eating undercooked or contaminated meat, cross-contamination, or consuming food that has been sitting out for too long can result in foodborne illness such as E. coli or salmonella. It is important to practice safe food handling and consume fast food in moderation to maintain good health.
