USDA Hog Slaughter

July 12, 2006 on 10:20 am | In Offal | Comments

meat lab signThis past january i went to Iowa for a meat seminar at Iowa State University Meat Labratories, and on the last day they were harvesting 4 hogs. As you can see in the photos this is done like precision clockwork, each person knows their job and it is done quickly and respectfully. All the while it is done under the close eye of a USDA inspector.

The process starts by the hog walking into the stun pen on its own.

Once the hog is in the pen, an electrode with 2 pads is placed behind there ears and there is a charge to stun the animal.

The hog is then hung upside down over the blood
bucket and one quick incision is made to bleed the hog.

The hog is left whole and placed into the scalder to remove the fur. Notice the organs are still inside the carcass.

The hog is then scraped with skinning knives to remove any fur that didn’t come off in the scalder.

The hog is then hoisted up and moved 2 feet over to have the hair from the feet and head removed by a torch. Next the head is removed.

Then the hog is eviserated by spliting the belly from the groin to the mid chest, being sure not to puncture any of the organs.

Then the organs are placed on a table for the USDA inspector to view and approve for consumption.

Finally the carcass is split in half by the huge spliter and then sent to another room to dry and be chilled.

  1. This is great that you blogged this with photos and all.

    One question, they “stun” the pig with the electrodes, but when exactly does the pig expire in this procedure…?

  2. Wow, I never realized it was so simple. I figured there’s be more to it. Thanks for the post.

  3. Much lip service is paid to the idea that we should know where our food comes from, but you’re a brave soul to blog it with photos! How long does the process take from start to finish?

  4. Jeez, this is what happens when 4H membership declines.

    Pretty soon we have picture exposes of how supermarket chickens are cut up it pieces, how fish are cleaned, and how tomato sauce actually comes from … tomatoes.

  5. For Tim Holmes…dude…what do you think the Blood Bucket is for? That’s how they kill it, bleed it out. After that, it’s just meat.

  6. I used to help my mom kill chickens and ducks as a child and we even kept pigs once, never again. As they smelled terrible and were hard to kill, the squirming and squeeling were just too much for us. I did however accompany my mom to friends houses/farms and witnessed a pig slaughter once or twice, they were gruesome. No thanks.

  7. Can you use the blood in cuisine easily? Or is it just disposed of? You mention how the organs are approved for use, but not what happens to the blood.
    In Tuscany I used to eat pig’s blood crepes. Sprinkled with Parmesan Cheese. An interesting one. Always wanted to try and repeat it, but it is REALLY hard to get a hold of the stuff here.

  8. I helped my parents kill two pigs last fall. We shot them twice in the head with our rifle (we learned that you draw a line from one ear to the opposite eye and again from the other ear and shoot them there). I have to admit they sure do move around after death. Trying to bleed them out after shooting them was a frightening experience, then getting them pulled up of the ground to drain the blood. I saved as much blood as I could, added some vinegar to stop coagulation and then used it to thicken several sauces I made to go with the pork. It was hard work, but educational (for a chef) and lots of fun seeing the entire process.

    We are doing it again this fall as well. My parents are picking up 2 Bershire piglets next monday.

  9. […] Since then, I found Offal Good (see what they did there?) a blog by Chris Cosentino. He has a post that pictorially details the slaughter process at the Iowa State University Meat Labratories. […]

  10. Good blog with photos for commerical slaughtering. I am wondering if there is another way of knocking the hog out before sticking and bleeding?

  11. […] This is an interesting blog I found dedicated to the use of the parts of the animal that are usually not looked upon as very useful and very old school. But useful the are! Pates from the livers, Sausages from the intestines & blood and Testicles for… well, i think I may pass on that. That said, I’m quite a big fan of most offal, and a nice bit of calves liver with a veal jus & mashed spud is pretty hard to beat… This page shows the slaughter of a pig from ‘go’ to ‘whoa’ complete with pictures…. bloody fantastic… […]

  12. Filipinos, not wanting to waste any component of a food source due to economic reasons, just being frugal, and growing up appreciating the flavor of a source of protein, tend to use every bit an animal’s or fowl’s part. Blood is used in a vinegar, garlic, pepper stew with meat & offal, usually intestines. See Wikepedia’s entry: Dinuguan

    “Dinuguan is a popular Filipino dish also known as pork blood stew or chocolate pudding. It is a savory stew of blood sausage and offal simmered in a rich, spicy gravy of pig blood, garlic, chili and vinegar. The term dinuguan comes from the word dugo meaning “blood”. It is recognisably thick and dark, hence the Westernized term “chocolate pudding”. … It is often served with white rice.”

  13. The way of life of the small farmer who only has a pig or two (or any other livestock) for their own use is threatened by an insidious program where the USDA wants to track the whereabouts of EVERY single farm animal 24/7 and know within 24 hours when it is born and killed. This program also includes pet pigs kept in suburbia.
    Don’t believe me? Check out nonais.org.

  14. thats nasty!

  15. I have been know to frequent the local farm lots after 4H or FFA season is over, looking for a hog for the freezer. You will never ever buy pork in a market like that.

    If god did not want us to eat animals, why did he make them out of meat?

  16. @ SUSAN

    What you said about the USDA is completely false, you do not need to inform the USDA about you own livestock. The USDA is only there for Market meat, they just have to check for deseases in the animals guts and carcass, and assure that the proccessing area is up to a clean standard. As should be the fake of all other food industries. Kids have died from e. coili in apple juice because workers didn’t do their job cleaning and using GMP, so try again. No pets need to be logged.

  17. I work in a small pork plant, we skin them, but I prefer the rind on method, gives it something extra. Who needs footballs??

    Comment by Justin — November 17, 2006 #

  18. I worked at a pork plant in Storm Lake Iowa about 16 years ago, but only for a short time. I got a real feel of the process. They shock the pigs and then slit their throat, letting them bleed to death. I washed and boxed the stomachs to be sent to Oscar Meyer for them to make bologna. I saw how they make sausages and hotdogs and still eat all of it today. In fact I just finished a bologna sandwich. Then they moved me to a position in which I was to position the hogs as they come out of the de-hairing machine so the guy next to me could hook the feet to hang up. It was quite the experince and wasn’t the best of smells either.

  20. Justin, it’s you who is incompletely informed. Susan is correct.

    As she indicated, USDA has been pushing a mandatory tagging system for all livestock in the U.S., including those kept as domestic pets. Perhaps you find this hard to believe? Well, educate yourself. Google the National Animal Identification System and wade in all the information you would ever want on this topic. Most recent word is that USDA is backing off from making it mandatory. Time will tell.

  23. In Goa - India we do this process manually and the blood is not allowed to spill out.It is warmed in salt and used as an adjuvant in a delicacy known as Sorpotel.

  24. Justin:
    by 2009 there will be tracking on all livestock (excluding horses, they are optional). it’s to prevent/follow diseases and outbreaks.
    animals and farms will need to be registered with a database, and the wherabouts of the animals recorded and sent in within 24 hours of relocation…

  26. I was told that a neighbor recently shot and slaughtered a pig in his backyard. Why are people so shocked about this?

  32. I used to work at a small meat processing plant and I couldnt help but notice how laid back of a job the usda inspecter had. He only came in on killing days and even then he just went around with his little stamp certifying all the meat. the bad part was that the plant was filthy and if i was the inspector it would have been shut down. I have butchered many animals outside on a picnic table and my setup is always cleaner than the processing plant. that said the usda is crap and everyone should work toward home butchering

  36. Everyone chill out. This has been going on for hundreds of years. Only difference now, is that we have fricken technology to show it to you on screen. Todays technology is a lot more frightening than slaughtering pigs. So sit back and relax, and be taken in.
