"The Gentle Cow"

When milk is raw
Just from the farm
It’s full of germs
While may do harm

But safe it is
And highly prized,
When it is boiled
Or pasteurized

Ice cream, cheese
And butter fat,
Come from milk,
You all know that

Made from raw milk
We can see,
They might harm
Both you and me.

Emily Berliner, Muddy Jim and other Rhymes (1919)
