As a beekeeper, there’s nothing quite like the satisfaction of harvesting golden, fragrant honey from your own hives. You’ve worked hard to nurture your bees, protect the colony, and ensure they have access to the best nectar sources. But what if, after all that effort, something seems off with your honey? Maybe it smells a little funky, looks cloudy in a strange way, or even has unexpected bubbles. Does honey really go bad? And if so, how can you tell?
Honey has been prized for its long shelf life, dating back thousands of years to ancient Egypt, where archaeologists have discovered jars of honey still perfectly edible. This natural preservation power comes from honey’s low moisture content and antibacterial properties. However, while honey rarely “spoils” in the traditional sense, certain conditions can cause it to degrade, ferment, or become unsafe to consume.
Whether you’re checking honey in your hive or inspecting jars stored in your pantry, it’s important to recognize the warning signs of bad honey. In this guide, we’ll walk through what can go wrong with honey, how to prevent spoilage, and what to do if you suspect your honey has turned. Let’s dive in and make sure your liquid gold stays as sweet and pure as nature intended!
Signs That Your Honey Is Bad in the Hive
Not all honey harvested from a hive is safe for consumption. Beekeepers should watch for these warning signs:
Fermentation: If honey in the hive has a sour or alcoholic smell, it may have fermented due to excessive moisture content (above 18%). This can result from high humidity levels or improper capping by the bees. Honey that ferments will also often have visible bubbles, a foamy surface, or may even begin to leak out of comb cells. This is a strong indicator that moisture has compromised the honey, making it unfit for long-term storage or consumption.

Mold Growth: Though rare, mold can develop in uncapped honey when exposed to excess moisture and contaminants. This can occur if bees fail to cap their honey properly or if an external source of contamination—such as a dead bee or organic debris—finds its way into the honeycomb. Moldy honey may have a fuzzy or discolored appearance, and in severe cases, it can spread through multiple combs, ruining a large portion of your harvest. If you detect mold in your hive, remove and discard the affected frames immediately to prevent further spread.
Pest Infestation: Small hive beetles, wax moths, or ants can contaminate honey, making it unsuitable for consumption. Small hive beetles, in particular, lay eggs in the comb, and their larvae can tunnel through honeycomb structures, causing honey to ferment and take on a slimy, unusable consistency. Wax moth larvae may also create webbing in the hive, introducing waste that spoils the honey. If pests are found in your hive, it is crucial to take immediate action, such as freezing infected frames or using beetle traps, to prevent further contamination.
Signs That Your Stored Honey Is Bad
Honey stored improperly can degrade over time. Look for these indicators:
Fermentation and Bubbles: If your stored honey has developed bubbles, a foamy layer, or a yeasty smell, it has likely started fermenting. This happens when honey absorbs too much moisture, allowing natural yeasts to activate and produce alcohol. The presence of bubbling or frothing is a clear indicator that fermentation is occurring. If the taste is sour or alcoholic, the honey is no longer suitable for regular consumption. For more information, check out our article: 3 Reasons Why Your Honey Smells Bad
Off Odors: A strong, sour, rancid, or rotten smell suggests spoilage due to microbial activity. Properly stored honey should have a pleasant floral or caramel-like aroma. If the scent has drastically changed or has an unpleasant mustiness, it may have been exposed to contaminants or excessive moisture.
Mold or Unusual Growths: Though rare, mold can form in stored honey if it has absorbed excessive moisture from the environment. Mold may appear as fuzzy white, green, or dark spots on the surface or along the inside walls of the container. If you notice mold, discard the honey immediately, as consuming it can pose health risks.
How To Prevent Honey From Going Bad
Proper storage and handling can ensure your honey remains safe and delicious for years:
-
Harvest Fully Capped Honey: Bees cap honey when its moisture content is low enough to prevent fermentation. Ensure that at least 80% of the frame is capped before extraction. If honey is extracted too early, it may contain excess moisture, increasing the risk of fermentation.
-
Store in Airtight Containers: Use glass jars or food-grade plastic containers with tightly sealed lids to keep moisture and contaminants out. Glass is ideal because it does not absorb odors or leach chemicals. Plastic containers should be BPA-free and food-safe to maintain honey quality.
-
Keep in a Cool, Dry Place: Store honey at room temperature (50-70°F) in a dark location, such as a pantry or cupboard. Avoid placing honey near heat sources like stoves, ovens, or direct sunlight, as excessive heat can degrade its enzymes and beneficial properties.
What Happens If You Eat Bad Honey
While honey is naturally resistant to most forms of spoilage, consuming bad honey can still pose health risks. Here’s what can happen if you ingest honey that has gone bad:
Digestive Issues: Fermented or moldy honey can cause stomach discomfort, bloating, nausea, vomiting, or diarrhea. Fermented honey contains alcohol and byproducts of yeast metabolism, which can irritate the stomach lining and disrupt normal digestion. If you experience severe symptoms, it is best to stay hydrated and seek medical attention if necessary.
Food Poisoning: Honey that has been contaminated with bacteria, fungi, or other pathogens can lead to symptoms of food poisoning, such as abdominal pain, vomiting, fever, and diarrhea. While honey’s antimicrobial properties make contamination rare, improper storage conditions (such as exposure to high moisture levels) can allow harmful microorganisms to thrive. Symptoms of food poisoning typically appear within hours of consumption and can last for several days.
Botulism Risk: Though rare, honey can contain Clostridium botulinum spores, which can produce a dangerous neurotoxin. This is particularly dangerous for infants under one year old, as their digestive systems are not yet mature enough to handle these spores. In adults, botulism poisoning is extremely rare but possible if honey is contaminated. Symptoms include muscle weakness, blurred vision, difficulty swallowing, and respiratory distress. If botulism poisoning is suspected, immediate medical attention is required.
Toxin Exposure: Some types of honey, especially those made from certain toxic plants, can contain natural toxins that may cause dizziness, nausea, sweating, and, in rare cases, neurological symptoms. If honey has an unusual or bitter taste, it is best to avoid consuming it.
Does Honey Go Bad at Room Temperature?
Honey is remarkably shelf-stable and does not require refrigeration. At room temperature, properly stored honey can last indefinitely without spoiling. However, exposure to heat, moisture, and air can lead to degradation, fermentation, or crystallization. Crystallized honey is not bad and can be restored by gently warming it in a water bath.
Final Thoughts
Honey is a gift from nature, offering both nutritional and medicinal benefits, but it requires proper handling to maintain its purity. By staying vigilant and recognizing the signs of spoilage, beekeepers and consumers alike can ensure their honey remains fresh and safe. With the right harvesting, storage, and usage practices, honey can last indefinitely, retaining its rich flavors and beneficial properties. Treat your honey with care, and it will continue to provide you with its golden goodness for years to come!
