yes quark, until very recently there has been no problem with cotc in america according to all (or certainly the majority) of major kashrus agencies. although the interview with R’ Vaye was from a year ago and indicated there IS a problem, he lives in Yerushalayim.
this apparently is a problem only a few weeks old, as far as i can tell so far, that is why i didnt know what the op was talking about in his anectodal reporting of an incident.
