Tylenol Recall

I am not saying this caused my son's health problems, but it is something we are definitely looking into. I would like an answer as to why a possible bacterial contamination of these Tylenol products is being announced now ? Over a year after the sale date of these products? I guarantee if you purchased any of these last year YOUR child has ingested some of the affected recall. I am disgusted that it took this long to get out.
