Why wouldn't soldiers eat meat of cows killed by their enemies?

Question

In the movie 1917, there is a scene in which Schofield takes a ride with a group of fellow British soldiers in a truck/lorry.

When they see dead cows lying around the road they are travelling on, one Indian soldier(a Sikh with a turban) says that it is clever for the enemy to kill the cows so that they would not eat them.

Why would they not eat meat from cows killed by their enemies?

Answer

As the other soldier noted, they used machine guns with the other remarking "Guns with extra bullets".

Implying the cows have so many bullets in them they can't be safely eaten, first is the issue of removing all the bullets from the animals corpse and secondly the lead that gets left behind is a high health risk to anyone who eats it.

This article speaks of the dangers of eating animals who got shot using lead bullets from even a single shot.
