Here’s How 1 McDonald’s Hamburger contains 1,300 strands of different DNA.

" This is the result of going from small farms to mega corporations

“We're pooling the bacteria from a thousand different animals”

“Thousands of animals” contribute “to a single hamburger”

“This is a combo bin of meat. The meat in these boxes comes from many different animals and many different places. Some is even from overseas. All of it is ground together to make the juicy hamburger Americans love. Hamburger used to be the scraps left over from butchering just one cow.”

But a significant change has occurred. Now parts of many cows are blended together by the ton.
‌
If we take the meat from one animal, grind it up and make ground beef from just one animal, we're including only the bacteria from one animal. But if we take the meat from a thousand different animals and grind that together, we're pooling the bacteria from a thousand different animals as well.

So explain this to me, how many different cows would be in one burger?

Well, I suspect that there are hundreds or even thousands of animals that have contributed to a single hamburger.”"
