Family Sick from Fast Food - In-N-Out, San Marcos California

583 Grand Avenue, San Marcos, 92078 California, United States

On Monday March 25th my family had In N Out. We ordered Double Doubles, Cheeseburgers, Cheese Fries, and a Milkshake. We all got diarrhea in the afternoon that same day. Two of my family members got nauseas and started vomiting. They couldn't hold anything down. They were so dehydrated and weak. Had to take them to the ER where they got medication to feel better. | Symptoms: Nausea, Diarrhea, Vomiting, Dehydration, Weakness
