FARGO, N.D. — A 1-year-old Minnesota boy who bit into a Tide detergent pod is being treated for poisoning at a North Dakota hospital.

Alexander Rohde of Hitterdal, turned 1 last week. He was flown to Sanford’s Pediatric Intensive Care Unit in Fargo over the weekend.

Family members said that Alexander thought the pod was a treat. He started throwing up and soon could not breathe. A hospital spokesman said Wednesday that Alexander was in critical condition but improving.

Alex’s mother, Michelle Klienschmidt, said that Tide should change the look of its pod. Tide said in a statement it’s working to educate people on keeping them out of the reach of children.
