That last sentence would be true as a stand-alone
sentence, but in context it implies something which
is not even remotely true -- that arsenic from
chicken feed additives has actually caused any
of the listed dread diseases in people.

In the U.S., the FDA tolerance level for arsenic
from roxarsone in chicken muscle meat is 0.5 ppm.
Wild-caught crabs, oysters, and clams from the ocean
would never be able to meet an arsenic level that low.
The tolerance limit is 76 ppm in crabs, 86 ppm
in clams and oysters.
