Hi there! I'm a food scientist specializing in food safety and microbiology. I've spent years researching the conditions that allow harmful bacteria to thrive in food, and I'm here to address your question about honey and botulism.
Let's dive into the science behind this:
## Understanding Botulism
Botulism is a rare but serious illness caused by a toxin produced by the bacterium *Clostridium botulinum*. This toxin, considered one of the most potent known, attacks the nervous system, leading to muscle paralysis.
Here's how botulism typically occurs:
1. Spores in the Environment: *Clostridium botulinum* spores are commonly found in soil and dust. These spores are incredibly resistant and can survive for extended periods in a dormant state.
2. Contamination: Food, especially improperly canned or preserved food, can become contaminated with these spores.
3. Anaerobic Conditions: *C. botulinum* thrives in anaerobic environments, meaning environments without oxygen. This is why improperly canned goods, where oxygen is removed, are particularly susceptible.
4. Toxin Production: In this oxygen-free environment, the spores germinate and produce the botulinum toxin as they grow.
## Honey and Infant Botulism
Honey is a unique food product that deserves special attention when discussing botulism, particularly for infants. Here's why:
* Spore Presence: Honey can contain *C. botulinum* spores. While rare, this contamination can occur naturally.
* Infant Gut Microbiome: Infants under one year of age have an immature gut microbiome. This means they lack the beneficial bacteria that compete with and prevent the growth of *C. botulinum*.
* Toxin Production in the Gut: In infants, ingested *C. botulinum* spores can germinate and produce the toxin within the intestine, leading to infant botulism.
**Therefore, honey should never be given to infants under one year of age.**
## Cooked Honey and Botulism
Now, let's address the specific question of cooked honey.
* Heat Resistance: While cooking can kill many bacteria, *C. botulinum* spores are highly heat-resistant. Regular cooking temperatures, even boiling, are not sufficient to destroy these spores.
* Honey Viscosity: Honey's thick, viscous nature can create pockets within the food where heat might not penetrate evenly, potentially allowing spores to survive even after heating.
* Toxin Inactivation: It's crucial to note that while cooking might not always eliminate spores, it can inactivate the pre-formed botulinum toxin. However, relying on heat to detoxify potentially contaminated honey is unreliable and unsafe.
**Therefore, while cooking might reduce the risk slightly, it is not a guarantee against botulism. It's always best to err on the side of caution and avoid giving honey, cooked or uncooked, to infants.**
## General Safety Tips
Here are some general safety tips regarding botulism:
* Safe Canning Practices: Follow strict guidelines for canning at home, ensuring proper sterilization and processing times to eliminate spores.
* Avoid Suspicious Foods: Do not consume food from bulging cans, jars with loose lids, or any food with an unusual odor or appearance.
* Temperature Control: Refrigerate perishable foods promptly and keep hot foods hot to prevent bacterial growth.
Remember, botulism is a serious illness, but it is preventable by following safe food handling practices and being aware of the risks associated with certain foods, especially for vulnerable populations like infants.

The botulism spores can only be killed by the high heat which can be obtained in a pressure canner. The toxin (that is produced in anaerobic conditions) can only be destroyed by boiling (WHO). So technically, honey is not safe for infants even in cooked form such as in baked foods like breads.
