From the article:
And to this day, the McRib comes and goes from the McDonald’s menu for reasons that have to do with its intense popularity and a national supply of pork trimmings that’s typically a lot more limited than the supply of beef trimmings.
“If you suddenly start to buy a large amount of that material,” said Mandigo, “the price starts to rise.”
As the cost to McDonald’s rises, the McRib tends to go out of circulation again. And then the same parts of a hog tend to flow back into the processing lines for Spam, Vienna sausages and other specialized products.
