Everything is satisfying if sausages are on the plate – a treat for your eyes, nose, and mouth. However, while cooking sausages in your skillet, you may notice slime on the casing. Does that mean your sausage is bad?

Well, not always.

Slimy sausage casing doesn’t always mean it’s spoiled. Natural casings are a bit slimy. However, there are several reasons to consider – bacterial action, inappropriate handling, and inaccurate storage temperatures. However, inspect for proof – discoloration or foul odor – along with slimy textures for decaying.

This article will explore the science behind slimy sausage casing and offer some tips for avoiding slimy sausage casing.

What Makes Slimy Sausage Casing?

What Makes Slimy Sausage Casing

The casing of sausage is made from the cleaned intestines of various animals. Pig intestines are the most common because they are the thinnest and have the least fat. The intestine is filled with natural collagen that helps to bind the meat together and keep it in shape.

But, as the sausage is cooked, that collagen breaks down and releases a slimy liquid. That’s why sausages often look slimy and gross — it’s not the meat itself but the casing that’s causing all the problems!

However, in the worst case, the sausage becomes slimy due to a type of bacteria called Lactococcus lactis. This bacterium thrives in the low-oxygen environment inside sausage casings and produces a slime known as exopolysaccharide.

While this sliminess might not seem appetizing, it plays an essential role in the shelf life of the sausage. It helps to keep the sausage moist and prevents it from drying out.

Again, the sausage casing can become slimy for a few other causes. The most common reason is that the sausage has been exposed to too much moisture. When the casing absorbs too much moisture, it can become soft and slimy.

Another reason the casing becomes slimy is if the sausage has been stored at too high a temperature. Excessive heat can cause the casing to release its water and become slimy.

What Happens When The Casing Of The Sausage Becomes Slimy?

The organic casing has two main functions: to protect the sausage from contact with the air and allow the sausage to be cooked evenly. However, the artificial casing is also now trendy, made using cellulose, plastic, or collagen. The artificial casing also does the same as the organic casing.

So, if the casing is made from the intestines’ inner layer, it exerts some organic change in the place. This layer comprises two types of cells: mucous cells and serous cells. The mucous cells secrete a glycoprotein called mucin that forms a slimy layer on the surface of the cells. The serous cells secrete a protein-rich fluid that contains enzymes and electrolytes.

If a sausage with a casing made out of animal intestine gets slimy, it does not mean the sausage is spoiled. The natural casing gives more of a slimy look than the artificial one.

However, if the casing becomes too slimy, the bacteria grow and reproduce. The slimy substance results from the bacteria releasing a slime to protect itself from the environment. The slime contains toxins that can harm the human body. So, you should throw out the sausage instantly.

The fact is that sausage casing from organic resources becomes slimy naturally; this sliminess indicates that these are fresh and you can eat them. If it starts to become too slimy, it means yes, it is starting to spoil.

However, synthetic casings are naturally not prone to be slimy in their fresh state. Therefore, if you see these become slimy, they start to spoil. So, the slimier the sausage casing, the more spoiled it is.
