Is Bacon With Melanosis Uberis Safe to Eat?

Bacon lovers, listen up. You may have encountered some strange black spots on your beloved breakfast meat before tossing it in the trash. Next time, don’t be so quick to dismiss it. Those spots may be harmless melanosis uberis.

I came across this phenomenon recently when my wife opened a pack of bacon with odd black speckles on every slice. My first instinct was to chuck it, worried it could be dangerous mold But a quick online search revealed it’s actually a natural, non-threatening pigment issue called melanosis uberis

In this article, we’ll explore what melanosis uberis is, what causes it, whether it makes bacon unsafe to eat, and how to prevent it. Let’s get to the bottom of this bacon abnormality.

What is Melanosis Uberis?

Melanosis uberis refers to black spots or streaks that can occur in pork, specifically in the belly area where bacon is cut from

It’s caused by the pigment melanin building up in certain spots Melanin is what gives skin and hair its color. We all have it in our bodies

In pigs, melanosis happens if melanin happens to concentrate in some areas. It’s perfectly natural and not due to any disease or infection.

The spots typically form during the growth and development of the pig. They remain visually evident even after the belly is cured and smoked into bacon.

Where Does the Name Come From?

The name melanosis uberis comes from Latin roots.

Melanosis refers to abnormal deposits of melanin, while uberis means “of the udder” or breast. So literally, “melanosis of the udder.”

This name stems from the fact that dark spots often occurred in pig breast meat or “udders” back when the condition was first studied. Today, we more commonly see it in pork belly destined for bacon.

What Causes Melanosis Uberis in Bacon?

Researchers aren’t entirely sure why melanin builds up in certain areas of a pig’s belly. But here are some contributing factors:

  • Genetics – Some pig breeds, like Duroc, seem predisposed to developing more melanosis. It runs in the family.

  • Sun exposure – Just like humans, sun exposure can stimulate excess melanin production in pigs. Outdoor-reared pigs tend to have more melanosis.

  • Skin irritation – Skin abrasions, infections, inflammation or injury can trigger melanin overproduction and melanosis spots.

  • Nutrition – Diets deficient in vitamin E and selenium may leave pigs prone to melanosis though the exact link is unclear.

What Does Melanosis Uberis Look Like?

The melanosis spots can vary in size, shape, color and distribution, but they have some common characteristics:

  • Color – Spots range from light brown to black. The darker, the higher the melanin concentration.

  • Size – Spots generally range from dime-size speckles to large black splotches over 1 inch wide.

  • Shape – Can be round, oblong, streaky or blotchy.

  • Location – Nearly always occurs on the belly portion (aka pork belly, bacon zone).

  • Distribution – While random, the spots tend to form in similar anatomical regions from pig to pig. They don’t cover the entire belly.

  • Depth – Only visually affects the outer skin layer, not the inner meat.

Is Bacon With Melanosis Uberis Safe to Eat?

The most important question for bacon lovers: Should you eat bacon affected by melanosis uberis?

The answer is yes, it is 100% safe to eat!

Melanosis does not make the pork unsafe, dangerous or unhealthy in any way. Here’s why:

  • It’s not microbial – Melanosis is not caused by germs, bacteria, viruses, parasites or fungi. Just pigment.

  • No contamination – The melanin spots don’t harbor any microbes or contaminants.

  • Non-toxic – Melanin is a naturally occurring pigment in the body and not toxic.

  • No decay – The spots don’t indicate spoilage, rot or decomposition.

  • Surface only – The spots affect the outer skin layer only, not the meat or fat.

  • USDA approved – Meat with melanosis is government inspected and federally approved for sale and consumption.

The only concern is aesthetic. Some consumers find the darkened spots unappealing. But safety-wise, melanosis poses zero risks. The pigment itself is harmless when eaten.

So if you find speckled bacon in your pack, don’t freak. Just trim off the affected areas if you don’t like the look of it. The remaining bacon is still perfectly good eating.

What About Mold in Bacon?

What if you spot furry white or green growth on bacon instead of dark spots? Could it be dangerous mold?

Yes, mold in cured meats like bacon can definitely occur and poses health risks if consumed.

With mold, you may notice fuzzy growth that can be white, green, black, or blue-green. It will appear elevated or hairy compared to flat, smooth melanosis spots.

Mold also tends to spread quickly across the surface if not contained. Melanosis spots are more localized.

And moldy meats give off a foul, musty odor, whereas melanosis does not affect smell or flavor.

So if you see spreading mold contamination rather than static spots, do not eat the bacon. Toss it and contact the manufacturer as you may have a spoiled batch.

Proper refrigeration is key to preventing mold growth in cured meats. But occasional melanosis spots do not indicate spoilage.

Can You Prevent Melanosis Uberis in Bacon?

Since melanosis stems from natural pigment variations, it can’t be prevented completely. But producers can minimize it by:

  • Selecting pig breeds less prone to melanosis, like Yorkshire pigs
  • Feeding a balanced diet with ample vitamin E and selenium
  • Avoiding skin damage and UV exposure in pigs
  • Swiftly curing and smoking bellies after slaughter

Higher processing temperatures may also destroy melanocytes and reduce spotting.

For commercial bacon, manufacturers typically trim off melanosis areas over 1 inch. But traces of spots can still persist.

If you end up with speckled bacon, just cut away the affected parts. The rest of the meat is good to go.

How Should You Store and Handle Bacon with Melanosis?

To inhibit mold growth and maintain quality, properly store bacon with melanosis like any other cured meat:

  • Refrigerate below 40°F

  • Seal in airtight packaging

  • Avoid moisture exposure

  • Use within 1 week of opening

  • Keep smoked meats separate from raw meats

  • Cook thoroughly to 165°F minimum internal temperature

  • Discard bacon with any signs of spoilage like mold, sliminess, or off-odors

With proper refrigeration and handling, bacon with melanosis uberis spots should remain safe to eat.

The Takeaway on Melanosis Uberis

What should you do if you open a pack of bacon only to find it peppered with dark spots? Remember these key points:

  • Don’t panic – The spots are melanosis uberis, not mold or decay.

  • It’s safe – Melanosis does not make the bacon hazardous, just less pretty.

  • Trim it – Cut away unappetizing spots. The rest of the meat is fine.

  • Check for mold – If you see fuzzy white/green growth, discard the bacon.

  • Store properly – Keep refrigerated below 40°F to inhibit actual spoilage.

  • When in doubt, toss it out – If you’re ever unsure, it’s not worth the risk.

While melanosis uberis may look strange, it’s a harmless pigment condition that doesn’t necessitate throwing out bacon. With proper handling, there’s no reason not to savor your breakfast favorite even with spots.

So rest assured bacon lovers, you don’t have to skip your morning meat fix due to melanosis. Just trim and enjoy the remainder responsibly. Don’t let a little pigment scare you away from the crispy, smoky, salty glory of bacon!
