Dried chillis were never identified as being a problem that I could see.
Dried chilies were never implicated in the US outbreak, only fresh, raw Jalapeño and Serrano peppers - not ancho or mulato chilies. The FDA tracked down the sources of the contamination, followed the distribution chain, and got them all removed. Had any been sent to another producer who made "dried" chillies from them - they would have been identified and removed from the food chain, also.
I sincerely doubt any got shipped to London. Had there been any concern in the UK I am sure the FSA
(your version of the FDA) would have issued warnings about it.
