So, as I waited to pay the toll in Decatur to cross the Missouri River into Iowa, I saw a tanker trunk in front of me. I wouldn't have payed much attention except for this warning on the back: "Inedible...something non-food grade something.....pork plasma.
First of all, when was the last time you wanted to order up some pork plasma for dinner? In fairness, I did eat pork blood in SE China, but it is served in little rectangles with a tofu-like texture and is tasty and salty, but still not common in american cuisine.
Which leads to the second thought that crossed my mind. Let's say you did have a hankering for pork plasma. With or without the "inedible" warning, would you really walk up to a tanker truck full of the stuff and try to get a swig? Curious.
And the third thought. What IS non-food grade pork plasma used for and for that matter what is food-grade pork plasma used for?
The googling effort on this will just have to wait.
