Who Cannot Have Mānuka Honey? Safety, Risks and Precautions

Mānuka honey is safe for most people, but certain groups - infants under 12 months, those with bee or honey allergies, diabetics, pregnant women and immunocompromised individuals - should avoid it or seek medical advice first.

Mānuka honey is one of nature's most remarkable foods. Harvested from the pristine landscapes of New Zealand, it carries a unique concentration of bioactive compounds that have made it one of the most sought-after honeys in the world. At Midlands Apiaries, we're proud to produce some of the finest Mānuka honey available - and as a producer deeply committed to quality and food safety, we also believe it's our responsibility to make sure people use it wisely.

The truth remains that Mānuka honey is safe and beneficial for the vast majority of people. But, like any potent natural product, it isn't right for everyone. If you're wondering whether Mānuka honey is suitable for you, a family member, or a customer, this article gives you clear, honest guidance on who should approach it with caution - and why.

Quick Safety Guide: Who Can and Cannot Have Mānuka Honey

A Quick Overview of Mānuka Honey

Mānuka honey is produced by bees that forage on the Leptospermum scoparium plant - the Mānuka tree - native to New Zealand. What sets it apart from regular honey is its high concentration of methylglyoxal (MGO), the compound responsible for its distinctive antibacterial properties.

Mānuka honey is graded using the Unique Mānuka Factor (UMF™) system, which independently verifies potency and purity. A higher UMF rating indicates a higher concentration of the key compounds - including MGO, leptosperin and DHA - that define genuine, premium Mānuka honey. This grading system gives consumers and retailers the confidence to know exactly what they're buying.

Many people incorporate Mānuka honey into their daily routines for its general wellbeing properties. But before doing so, it's worth understanding whether it's appropriate for your specific circumstances.

Mānuka honey is a natural product, but natural doesn't automatically mean it is universally safe. It contains natural sugars, plant compounds, and - in common with all honey varieties - trace levels of clostridium botulinum spores. 

For most healthy adults, these present no concern whatsoever. However, for certain groups, these factors warrant real awareness. Understanding these contents isn't about fearmongering. It's all about making informed, responsible choices - something we at Midlands take seriously at every stage of our production and communication.

People Who Should Avoid or Limit Mānuka Honey

• Infants under 12 months
• People with bee or honey allergies
• People with diabetes
• Pregnant or breastfeeding women (with caution)
• Immunocompromised individuals

Infants Under 12 Months

This is the most important safety message in this article: babies under 12 months must not eat Mānuka honey because of the risk of infant botulism.

All honey can contain spores of clostridium botulinum, the bacteria responsible for infant botulism. In adults and older children, the digestive system is developed enough to prevent these spores from multiplying. In infants, however, the gut is not yet mature enough to defend against them. If ingested, the spores can germinate and produce a toxin that causes the infant botulism condition - a serious, potentially life-threatening illness.

This risk applies regardless of the quality or potency of the honey. Even the world's most rigorously tested Mānuka honey carries this risk for very young children. The guidance from health authorities worldwide is consistent and unequivocal: no honey for babies under 12 months.

After the age of one, children can generally enjoy honey safely, and many families find Mānuka honey a wonderful natural addition to the family pantry.

People with Bee or Honey Allergies

Anyone with a known allergy to bees or bee products should approach Mānuka honey with great caution. Honey can contain trace amounts of bee venom, pollen and other compounds that may trigger allergic reactions in sensitive individuals.

Reactions can range from mild symptoms - such as itching, hives, or a tingling sensation - to severe anaphylactic responses in more serious cases. If you have a known bee or honey allergy, or have ever experienced an allergic reaction after consuming honey, it's important to consult your doctor or allergist before trying Mānuka honey.

For B2B sellers and retailers, it's good practice to ensure your product labelling includes clear allergen information so that customers can make safe, informed choices.

People with Diabetes or Blood Sugar Management Issues

People with diabetes can have Mānuka honey in small amounts, but only with medical guidance. Mānuka honey is still honey - and honey is a concentrated source of natural sugars, primarily fructose and glucose. While Mānuka honey has a lower glycaemic index than some other sweeteners, it can still cause a meaningful rise in blood glucose levels.

For people managing Type 1 or Type 2 diabetes, or those with impaired blood sugar regulation, this is an important consideration. Consuming Mānuka honey - especially in larger amounts - can interfere with blood glucose control and may affect medication effectiveness.

This doesn't necessarily mean Mānuka honey is completely off the table for people with diabetes, but it should be treated with the same care as any sweetener. If you have diabetes or a related condition, speak with your GP or dietitian before incorporating Mānuka honey into your diet. Small amounts, carefully monitored, might be appropriate for some - but this is a decision best made with professional guidance.

Pregnant and Breastfeeding Women

There is no definitive evidence that Mānuka honey is harmful during pregnancy or breastfeeding, and many pregnant women consume honey without any issues. However, because Mānuka honey is a particularly potent variety, and because individual sensitivities can vary during pregnancy, we recommend consulting a healthcare provider before making it a regular part of your diet during this time.

This is especially relevant for those considering higher-potency Mānuka honey (UMF 15+ or above), where the concentration of bioactive compounds is significantly elevated. As always, your midwife, obstetrician or GP is your best source of personal dietary guidance during pregnancy.

People with Compromised Immune Systems

Individuals who are immunocompromised - due to conditions such as HIV / AIDS, active cancer treatment, or long-term use of immunosuppressant medications - might be at elevated risk from foodborne pathogens, including the bacterial spores found in all honey.

While Mānuka honey's antibacterial properties are often cited as beneficial, the same spore risk that makes honey unsafe for infants can present a consideration for those whose immune systems are significantly weakened. 

If you or a patient falls into this category, seek medical advice before using Mānuka honey, particularly when considering it for therapeutic or medicinal purposes.

‍Additional Risks and Considerations

Medication Interactions

Mānuka honey's natural compounds may interact with certain medications, particularly those that affect blood sugar - including insulin and oral diabetic medications. If you take prescription medication, it's worth checking with your GP or pharmacist before adding Mānuka honey to your regular diet.

Dental Health

Like all sugars, the natural sugars in Mānuka honey can contribute to tooth decay if consumed frequently and without adequate dental hygiene. This is particularly worth bearing in mind for children and people with existing dental concerns. Rinsing your mouth with water after consuming honey, or timing consumption around mealtimes, can help reduce this risk.

Amount and Frequency

For those who can safely enjoy Mānuka honey, moderation is key. Most adults tolerate one to two teaspoons per day, either taken directly or stirred into warm water, yoghurt, or other foods. 

Consuming large amounts regularly isn't necessary - and may lead to an excess of natural sugars in the diet. More isn't always better, even with premium Mānuka honey.
