The first part of that is meaningless if not referenced to some unit weight. 13.2 micrograms per gram? per pound? per ton? the whole of that batch?

High lead content is unavoidable when factories resort to using wild licorice in their greedy quest for profits.
Every time a wild licorice is shot with lead bullets, lead contamination is the result.
“what happens to people who eat twice as much as others?”
They die and get sold to the scrap dealer instead of buried.
