I think it is interesting that it only mentions sweet paprika and not hot.
I'd say it's only comparatively recently (in the US at least) that anyone outside of serious foodies has been aware of the existence of hot paprika, much less of smoked paprika, which is more Spanish than Hungarian.
I found an interesting report from 2000 about an emerging paprika industry in Australia. The background includes;
>Historically, Hungary has produced the high quality condiment paprika required [by the marketplace], however, exports have declined significantly over the last 10 years. This is partly the result of heavy metal contamination caused by air pollution and bad publicity because of some Hungarian companies selling adulterated paprika. At the end of 1994 the Hungarian authorities had to destroy approximately 25,000 tons of adulterated paprika. Exports decreased significantly, with the Hungarians exporting virtually no condiment paprika to their traditional customers Czechoslovakia, Japan and Germany by 1994. The Hungarian research organisations tried to restore the reputation of their product by producing the famous paprika cultivars in overseas countries such as Israel, South Africa and now in Australia.
In 1994, there was a serious issue with Hungarian paprika being adulterated with lead oxide. It made the paprika redder and added weight to it. It also caused a lot of lead poisoning in people. A third of paprika samples tested were found to have lead. That would, indeed, rather put people off using Hungarian paprika.
