Beekeepers are frequently warned not to feed honey from untrusted sources to their colonies because it can carry the spores of American Foul Brood (AFB). Furthermore, we know the spores of AFB are not affected by standard pasteurization methods because they are highly resistant to heat. Pressure cooking at 250° F (121° C) for three minutes will kill the spores, as will other combinations of temperature, pressure, and time.
However, as “saving the bees” has become a popular activity for many people, non-beekeepers frequently write to me and explain how they are doing their part to save the bees by feeding them honey. For any number of reasons, these individuals cannot become—or do not want to become—beekeepers, yet they want to do something to help the honey bees.
When they write to me, I always take the time to explain the hazards of feeding honey, but of course I don’t know if they heed the warning or not. But more problematic are all the folks who don’t write, don’t ask, don’t know, and just assume they are doing the best thing for the bees. For every person who writes into a blog, there are thousands who don’t. And since I get a lot of e-mails about this, I assume the number of people feeding bees is staggering.
I have a picture in my mind of a scrupulous beekeeper, carefully tending his bees, taking precautions against the worst diseases, and doing everything by the book, while a neighbor down the road blithely buys imported honey from the grocery stores and fills a dozen feeders. It’s an uncomfortable thought.
So I began to wonder how often contaminated honey actually transmits AFB. We hear the warnings all the time, but I’ve never actually heard of a case where contaminated honey was thought to be the cause. So how common is American foul brood in honey? Come to think of it, how common is American foul brood in honey bee colonies?
The only time I ever saw AFB was in the hive of a friend, and that was many years ago. I seldom get mail asking about it. I’ve heard of a few recent cases of European foul brood, but not AFB. Nearly all the mail I get is about Varroa mites, deformed wing virus, nosema, CCD, chalkbrood, tracheal mites, and hive beetles, but nary a word about AFB.
So how common is AFB? How big of a problem are AFB spores in honey? Should we worry about scores of people feeding grocery store honey to any honey bee that wanders by? Or is foul brood in honey not a worry?
Adulteration of honey with sugar syrup and corn syrup has been a problem for a long time. An unscrupulous beekeeper can feed his colonies these products and extract them like honey, or he can add them later, after extraction. The financial incentive is obvious because syrup is cheap and readily available.
Naturally, importers of honey and large-scale purchasers of honey for manufacturing purposes have always been interested in knowing if the liquid they are paying for is pure, or if it has been “cut” with syrups from non-floral sources.
Cane and corn are C4 plants
It turns out that most plants can be identified as either C3 or C4 plants. Roughly 90% of all plants are C3 and about 5% are C4. The names C3 and C4 come from the first compound produced by the plants during the CO2 fixation stage of photosynthesis.
In a C3 plant, the first compound produced has three carbons, and in a C4 plant, the first compound produced has four carbons. A third type of photosynthesis called CAM is found in about 5% of plants, mostly succulents. Since many of these can switch between CAM and C3, they are sometimes included with the C3 species.
The C4 cycle is an adaptation of plants that evolved in very hot and dry climates. They are able to use CO2 more efficiently and they lose much less water due to transpiration, so they can thrive in sere conditions. Most C4 plants are grasses, including sugar cane, maize, and sorghum, and most are wind-pollinated.
Honey is made from the nectar of flowers
By definition, honey is made from the nectar of flowers. Nectar is secreted by nectaries, which are glands located in flowers, and the secretions are especially designed to attract pollinating insects. Some definitions also include secretions from extra-floral nectaries and the excretions of plant-sucking insects (honeydew) as honey sources.
However, the C4 plants maize (corn) and sugar cane do not have nectaries and are not known for producing honeydew. Sweet liquids pressed from the leaves, stems, or other herbaceous parts of a plant are not considered nectar for the purposes of honey, especially after they are refined by industry.
Isotope profiles can identify C4 syrup
C3 and C4 plants contain different ratios of the stable isotopes carbon-12 and carbon-13. Isotopes are different forms of an element. Each isotope of an element has the same number of protons but differing numbers of neutrons in the nucleus. Since extra neutrons affect the weight, they are easily detected
A carbon-12 atom has 6 neutrons and a carbon-13 atom has 7 neutrons, but they both act like carbon. These isotopes do not decay and are not radioactive, hence they are “stable” as opposed to the unstable type that decay and are radioactive. A carbon isotope we have all heard of is carbon-14, which is a radioactive isotope with a very long half-life of 5730 years. By measuring how much of this isotope remains in a very old object, we can determine its age.
In any case, since these heavy carbon atoms are measurable, it is easy to discover if a sample of honey is adulterated with syrups derived from sugar cane or corn by measuring the ratio of the stable isotopes, 13C/12C.
Sugar beets are C3 plants
However, a problem occurs when syrup is derived from beet sugar. Beets are C3 plants and have the normal ratio of stable isotopes found in most nectar-producing plants. So honey contaminated with sugar beet syrup is not detectable with this method.
As you can see, contamination with syrup is an unresolved problem. Isotope analysis is not readily available to the average consumer, and beet sugar adulteration cannot be found in any case. If you are concerned about the content of your honey, it is best to know your beekeeper. . .and know him well.
Why? Because conditions are not right. Pure and simple.
This time of year, new beekeepers are asking why their bees will not fill the honey supers or even visit the supers. Some report their bees walking around inside only to leave again, uninterested. Some blame queen excluders. Others believe they are doing something wrong. But most want to know how to “make” their bees store honey.
First off, you can’t make a honey bee do much of anything. Like teaching a pig to sing, you might be able to encourage certain behaviors, but it might not be in your best interest.
A colony needs time to establish
Let’s look at what happens when a new beekeeper starts a colony in a new hive. New bees—whether in a package or in a nuc—most often arrive in the spring. Spring is when most major honey flows occur, but a new colony has a lot of work to do before it can begin storing surplus honey.
Most pressing is raising lots of young. To do that the colony needs to build brood comb and collect food to feed the young. It needs to feed drones. It needs to fill the pantry with supplies, but first it has to build the pantry. It needs to collect water to cool the hive. It needs to defend itself. All of these chores take lots of energy which is readily available because it is spring and flowers are abundant.
New colonies expand on the nectar flow
From the beekeeper point of view, the hive is exploding and will soon be able to fill the honey supers. But just when you eagerly plop the honey supers atop the hive, the spring flows are winding down. The days get warmer and the flowers get scarce. You’ve raised your bees on the spring flow, but the flow is over and the bees have no motivation to draw out your supers because there is nothing to store.
When the nectar flows dry up, the days get hot, and the hours of daylight are less—think summer solstice—a colony shrinks the brood nest. Not as many bees are necessary to keep things going, so less space is devoted to nursery. The shrinking nest allows more nectar to be stored in the immediate area, and the bees will fill this instead of filling the supers.
A nuc has a much better chance of putting away some surplus the first year simply because part of the work is already done. But regardless of how the colony starts, it needs to get through the to-do list before it begins storing surplus.
Other factors also affect how much honey a colony will store, regardless of whether it is new or old. The climate and local weather is critical as is overall colony strength, genetics, available forage, and environmental stressors.
It’s all about the flowers
A beekeeper has to understand both the rise and fall of colony populations and the ebb and flow of nectar. In most places in North America, for example, we have one or more strong spring flows, followed by a dearth in mid-summer and, in most areas, a fall flow that may or may not materialize. These patterns vary depending on where you live, but once you learn the bloom schedule in your specific area, you will have a better idea of what to expect from year to year. Remember, beekeeping is all about the flowers.
I think it is a mistake for a new beekeeper to expect a crop the first year. There are exceptions, of course. But we all can’t be the exception.
Tricking your bees into building in the supers by baiting them with a frame of honey, for example, is not always the best thing to do. If you get them to store honey in the supers before the brood boxes are full, you may end up harvesting honey that they need for winter survival. You—and they—are better off if they are allowed to fill up the brood boxes first. Then, if they are healthy and make it through the winter, your bees can build up before the spring flow instead of building up during the spring flow, and you will gets lots of honey.
A word about queen excluders
Through the years, I have waffled over the use of excluders. I used to believe—as many others do—that queen excluders are honey excluders. In the past, I always put a section super directly above the brood box and it usually kept the queen away. But after more than a few ruined sections, I’ve gone back to queen excluders.
I’ve discovered that with an excluder, the bees will be more apt to store below it at first. But this gives them a good honey supply for winter because they fill every nook and cranny of the brood boxes. Once the boxes are full, however, the colony will burst through the excluder and fill up supers in a matter of days. It depends on the strength of the flow of course. This year I had nothing in the supers, nothing, still nothing, discouraging nothing, than bam! Full in a few days. Crazy full. Need-help-lifting-them full.
Sure, some colonies did not pass through the excluder, but I don’t think they would have stored surplus anyway. Not all colonies are created equal, and not all colonies will provide surplus every year.
A word about patience
We are used to instant gratification. We want honey and we want it now. But nurturing bees is more than collecting their honey. If we concentrate too much on the end product, we are missing the wonder of honey bees. The question, “How soon can I get honey?” always worries me. So does the beekeeper who buys an extractor along with his first package. Harvesting should not be your first thought.
This, I think, is why the hype about the Flow hive annoys me. All the concentration, all the focus, in fact the whole purpose of the Flow hive is to take the bees’ honey quicker and easier. Proponents say it’s better for the bees, gentler (as if stealing someone’s food supply is ever “gentle”). But when a first-time beekeeper starts with a Flow hive, his focus is already on the harvest. He’s calculating what’s in it for him before he’s ever seen a bee up close and personal.
If you take time to become a good beekeeper, you will have plenty of honey. You will have honey for years and years and years. Learn how the system works and your honey crops will come.
Update: Included at the end of this post is a statement by Katie Sanchez of Bee Free Honee.
Honey is excluded from the vegan diet by definition. Both the definition and the term “vegan” are credited to Donald Watson, who promoted the idea back in 1944. A few months later, the Vegan Society of England adopted Watson’s model. He wrote:
Veganism is a way of living which excludes all forms of exploitation of, and cruelty to, the animal kingdom, and includes a reverence for life. It applies to the practice of living on the products of the plant kingdom to the exclusion of flesh, fish, fowl, eggs, honey, animal milk and its derivatives, and encourages the use of alternatives for all commodities derived wholly or in part from animals.
So if honey is included in the official definition, there is no doubt that honey is off limits to vegans. I am frequently asked why honey is vegan, and knowing this will make it easier to answer.
But here is my question: Recently my daughter—who is vegetarian but not vegan—found a recipe that calls for “3 tablespoons of vegan honey.” She asked me, “What the heck is vegan honey?” Good question. As she points out, the phrase is confusing. Like fat-free half-and-half, it defies all manner of logic.
So I did an internet search. Lo and behold, you can buy something called “Bee Free Honee” that is made from concentrated apples, beet sugar, and lemon juice. At least one reviewer says it’s “even better than the real thing.”
Personally, I doubt it’s better than the real thing, especially since it comes in four flavors that don’t particularly remind me of honey: original, mint, chocolate, and ancho chili.
But the thing that’s most baffling? The label. It reads “All Natural • Plant Based.” While that is no doubt a true statement, you could say the same thing about honey: both are all natural and plant-based. Honey is made from nectar, and nectar comes from plants. Okay, maybe a bit of bee spit too, but when apples are pressed, all kinds of bugs and caterpillars, wormy things and slugs, get squeezed along with the fruit.
Some lifeforms are hard to avoid. According to the FDA Defect Levels Handbook, apple butter (which is also a form of concentrated apples) is not flagged until the 100-gram samples contain an average of four or more rodent hairs and 5 or more whole or equivalent insects (not including mites, aphids, thrips, or scale insects). These levels are set for aesthetic reasons only, and it sounds like the mites, aphids, thrips, and scale insects are so small that they are not even counted. So much for vegan.
And speaking of animal exploitation, I wonder who pollinated all those apple trees? And the lemons? Is it possible that bees were stacked on a flatbed and trucked across the country, servants to the ag industry? Is it possible that apples and lemons are “commodities derived wholly or in part from animals” or their labor? One reviewer wrote, “No bees die in the production of no-bee honey.” I wonder how sure she is about that. Both agriculture itself, and the migratory beekeeping that serves agriculture, are very hard on bees.
I certainly have nothing against veganism: people should be free to eat what they want. But I find it odd that people take labels at face value without evaluating the subtleties—the details about where food comes from and how it’s processed.
At any rate, consider this a public service announcement for beekeepers: now you know where to send your vegan friends who can’t eat honey. But for the record, I don’t understand why vegans condone consumption of bee-pollinated crops or the ingestion of insect parts that are invariably part of our food supply. To me, that is no less abusive than eating honey—bees die either way.
Thank you Rusty, for allowing me the opportunity to respond to your blog and the thread of comments following your discovery of Bee Free Honee. I would like to begin this is my product: I created it (by accident). I was trying to make apple jelly and did not read the directions. Later, I began to hear about the decline in the honey bee and began to learn more about what was happening in the industry and asked myself: Can I do something with that mistake?
My father was a beekeeper growing up; most of my life bees were our closest neighbors. I love bees and all pollinators and have a great deal of respect for them. I grew up around people that believed in doing things simply, naturally. As I got older and moved away from home, I lost touch with that world so I was shocked to find how much beekeeping had changed since my last exposure to it. I began to learn about national hive renting and local hive renting and their differences. I learned about nutrient deficiencies for our pollinators due to farming practices, grooming of the roadsides, and clearing land for construction spreading into rural areas. I read articles on the decline of the honey bee and realized that what was being put out was not a call for action but a way for people to get mad about governments allowing certain pesticides and cell phone use…but not a demand for change. I looked in the stores and saw shelves of honey, honey sold by the gallon all year long, not seasonally as I knew it to be.
I realized this is not only about neonicotinoids and cell phones; this is also about our expectations as consumers to purchase honey all year round and in unlimited quantities, at a low cost. This is about pollinating fields at the expense of the insects, without allowing the costs of maintenance of the hives cut into the bottom-line. Could almond growers have their own hives, they could but they do not want to. The reasoning given is that there is not enough water or food for the bees to live on; some orchards say it is too hot for the bees and no shelter to protect them; the bees would cook in the hives. Well, there are solutions for all of that…it is not an overnight solution but we can make this work. First of all, we build shelters for all other animals; we could build simple shelters for bees. Water is provided for livestock; why not provide it for bees. Green walls are now very water efficient, they could be built strategically to provide the nutrient diversity for the bees, and as they are built vertically, they take up almost no land. This would also increase the amount of water that is put back into the atmosphere through transpiration. According to http://water.me.vccs.edu/courses/SCT112/lecture3_print.htm : “For example a large oak tree can transpire 40,000 gallons of water per year. About 10 percent of the earth’s atmospheric moisture can be attributed to plant transpiration. The rest is supplied by evaporation and the water cycle.” The fewer greenery the less transpiration – likewise, increase greenery and produce more fresh water.
Think of the good for our fresh water supply, cleaning up the air quality, and for our pollinators if we began to build green walls strategically. Think of the good we could do if we kept bees stationary, if we began to treat them as the beautiful special and important insect that they are. Not just think of them as a means to a commodity. Why is there not more education on the Mason bee? They are less aggressive, native to our country and easy to house….and very effective pollinators. Maybe because they don’t produce a commodity?
Through Bee Free Honee, I do my best to educate the public on these topics as well as asking them: If you are buying honey simply as a flavor profile in cooking or baking; Why not find an alternative that will provide the same result but allow the bees some time to regain in strength and in numbers? We cannot just continue on business as usual and expect it to be okay. We need to make changes. I do understand that change is hard. I do understand that there will be people who will never understand or approve of what we are doing. But to reduce it to being simply vegan does not do it justice. Vegan is one attribute of our product, another is that we need to save the bees and I am trying to do something about it in any and every way I can. It may not be the method others would choose but that is why we value the freedoms our country affords us. So we can all go forward in our own individual ways.
We try to be very clear about what Bee Free Honee is. When we did use beet sugar, it was non-GMO, but that local farmer sold his field to a company that planted GMO beets, so we switched to Vegan quality, non-GMO cane sugar. We use only as much is as needed to create tackiness, no more. Lemon juice is the only preservative and the rest is apple. That is it. From every angle of the bottle we clearly write that we are from apples and even have the words “contains no real honey” on the bottle. The word ‘Honee’ is a descriptive; ‘Bee Free’ refers to the process in which it is made, not to how it was pollinated.
I hope this clarifies our stance, if you would like to read more, we have a page on the bees on our website that talks about our stand, and there is a page on how it all got started. I hope you feel comfortable taking a look through the site. I hope you are able to see that we are trying to create a positive. Thank you for your time.
Robert Lunsford from down in Louisiana wanted to know what was up with his honey, so he sent the following three photos of shimmery, iridescent honey that seems to glow from within. Awesome looking stuff!
My theory is simply this: I think he had at least two different types of honey in the pot. One of the types was much higher in glucose than the other, so it began to granulate much more quickly.
It looks to me like they were not thoroughly combined, but just stirred a little bit—the way you would make a marble cake or strawberry swirl ice cream. The result was ripples of granulated honey suspended in liquid honey. Because honey becomes lighter in color when it granulates, the nearly white but opaque crystals could easily be seen through the darker, but still translucent liquid honey.
I figured that it would all soon granulate, especially since it was now seeded with crystals. Sure enough, by the time I requested permission to use the photos, Robert reported that it had all granulated into a fine-grained, silky smooth, and creamy consistency.
Has anyone else seen this? I thought the photos were great.
