My son found eating toilet brush

Patient: I am very worried as my 21 month old son was found with a toilet bowl brush in his mouth earlier today. At first I didn’t think much about it but then tonight he woke up and had puked everywhere. He puked 3-4 more times before he finally fell asleep again. He was very pale looking. I fear he has ingested some harmful bacteria. Could this be a serious thing and should I bring him in to the emergency room?
