Fig. 7. -- Two gizzards, one from a mallard dosed with lead. Food impaction of the glandular stomach 
commonly occurs in lead-poisoned mallards. The glandular stomach attached to the gizzard shown in 
upper part of illustration was distended by small grains. No fat deposits were found around the gizzard. 
The proventriculus and gizzard shown inlower part of illustration were removed from an undosed mallard. 
LEAD-POISONED DUCKS AS FOOD 
Some sportsmen have asked if they themselves canbecome poisoned by eating the flesh of ducks 
that are suffering from lead poisoning. 
That the flesh of lead-poisoned ducks can be eaten by human beings without ill effect is indicated 
by studies made with laboratory animals that received doses of lead salts. Analyses of muscle and skin 
of these animals for lead content generally failed to reveal the presence of lead deposits. The liver and 
kidneys are more likely to contain lead than the muscular tissue; yet the livers of lead-poisoned ducks 
were found to contain amounts of lead of negligible significance to human beings. 
A further protection against the transmission of lead poisoning from ducks to human beings lies 
in the fact that waterfowl severely affected by lead poisoning are too emaciated to be regarded as suit- 
able for the table.
