Pork Kidneys – Exploring the Journey from Livestock to Plate

Pork is one of the most commonly consumed types of meat across the globe. Pork kidneys, in particular, are a versatile and flavorful offal that can be enjoyed in a variety of dishes. But just how do pork kidneys make their journey from livestock to plate? In this blog, we will explore the journey of pork kidneys from the farm to your dinner plate.

Pork Kidney Origins

Pork kidneys come from domesticated pigs, which are a popular livestock animal and originate from Eurasian wild boar. Pigs are raised for their meat, sometimes referred to as ‘pork’, or for the production of certain products (such as lard or medical purposes). The kidneys of the pig are referred to as offal and can be eaten (as in the case of pork kidneys), or alternatively used in a variety of processed products.

When breeding pigs, breeders are careful not to breed too closely to related animals - inbreeding is avoided as it often results in genetic health complications. As an example, if a breeder wanted to produce a pig that grew more quickly they wouldn’t breed a sow and boar of the same family. Rather, they’d select different sows and boars that are genetically diverse in the desired characteristics they are aiming to 'breed in’. Furthermore, if the breeder wanted their pig to grow more quickly yet have more meat, they may consider selection for less fat deposition (including using animals with lower fat and higher muscle). Both of these variables (relatedness and fat deposition) impact the final product: the pork kidneys.

Pork Kidney Production

Once the slaughtering and de-boning of the pig is complete, the kidneys may be hand-sorted or mechanically sorted. If hand sorting is done, workers have to be highly trained as they must recognize the distinct shape and external fat deposits which indicate whether the kidney is fit for consumption or not.

In order to make sure that the pork kidneys are preserved in the best condition, there are several inspection procedures to follow including: visual inspections, measurements, and color analyses. For instance, the overall shape and the cut surface appearance of the organ should be evaluated for any abnormalities or signs of spoilage. The fat deposit around the kidney should be noted, and the organ should be evaluated for any trace elements like blood or fecal matter.

Once the onions are adequately clean and inspected, they are placed in sealed packaging and stored. Many producers will also add preservatives like minerals and vitamins so that the pork kidneys stay fresh for longer periods of time.

Transport and Distribution

Once the pork kidneys are packed, they are transported according to the regulations laid out by the government health department. This typically involves transporting the organs in temperature-controlled environments. The USDA recommends that raw organs be kept at temperatures between 41-45 degrees Fahrenheit (or 5-7 degrees Celsius) throughout the transportation process.

The kidneys are then either delivered directly to their final destination (like a grocery store, restaurant, or butcher) or shipped to a centralized warehouse and distribution facility where they are sorted and shipped out to localities and stores. In the case of a large-scale butcher which serves entire cities, they may have their own warehouse and distribution centers similar to a large-scale restaurant.

At the store or restaurant, the pork kidneys will be inspected again before being put on shelves or refrigerators. At these points, the pork kidneys are ready for purchase by consumers.

Cooking Pork Kidneys

Before you start cooking pork kidneys, it’s important to understand that due to the presence of urate crystals, cooking them can cause them to turn green or discolored. To avoid this, you should soak the pork kidneys in salted water and/or rinse them a few times before cooking.

The kidneys should also be cooked low and slow as they are made of muscle tissue and require a longer cooking time to break down the tough connective tissues. Make sure to dry the kidneys with a paper towel before searing them in a hot pan. Once the kidneys are seared, you can move them to a slower cooking method like braising or stewing.

If you’re looking for a classic dish, try breaded and fried pork kidneys. You can also enjoy pork kidneys in curries or in traditional British dishes such as steak and kidney pie. Either way, the key to getting tender kidneys is low and slow, so just be sure to keep an eye on the cooking process.

Conclusion

From the farm to your dinner plate, pork kidneys have an interesting and intricate journey that has been explored in this article. From careful breeding and selection by breeders to sorting, packaging, storing, and cooking, pork kidneys have a significant journey - as do all types of meat.

By understanding the full journey of pork kidneys, consumers can make an informed decision when buying and eating pork. Keeping an eye out (or asking your local butcher or farmer) for the right handling and storage conditions, can help ensure the quality of the meat and thus, a better meal.
