Tea is a popular beverage consumed by millions of people worldwide, and such a widespread consumption also means that it’s crucial for tea drinkers to be aware of the potential health risks of mold in tea. Mold can grow in different types of tea, and it’s important to know the causes, identification, health risks, prevention, and measures to take when you accidentally drink moldy tea.

Understanding the Causes of Mold in Tea

Mold can occur in tea leaves when they are exposed to moisture or humidity. This can happen in tea leaves that are improperly stored or packaged, or when tea is prepared using contaminated utensils or equipment. Furthermore, if tea is stored in an environment with fluctuating temperatures, it can increase the chances of mold growth.

It is important to note that certain types of tea are more susceptible to mold growth than others. For example, black tea is less likely to develop mold than green tea due to its lower moisture content. Additionally, tea that has been stored for a longer period of time is more likely to develop mold than freshly packaged tea. To prevent mold growth, it is recommended to store tea in a cool, dry place and to use clean utensils and equipment when preparing tea.

How to Identify Mold in Your Tea

Mold appears in different forms, ranging from furry textures to small black spots on the tea leaves. Sometimes mold has a fuzzy or cottony texture, and when you touch it, you might feel a dampness or mildew odor. If you observe such signs in your tea leaves, it’s important to discard it immediately to avoid any health risks associated with mold ingestion.

It’s important to note that mold can also grow in tea bags, especially if they are stored in a damp or humid environment. To prevent mold growth, it’s recommended to store tea bags in a dry and cool place. Additionally, if you notice any discoloration or unusual smell in your tea bags, it’s best to discard them.

Some people may be more sensitive to mold than others, and may experience allergic reactions such as sneezing, coughing, or skin irritation. If you suspect that you have ingested moldy tea and experience any of these symptoms, it’s important to seek medical attention immediately.

The Health Risks of Drinking Moldy Tea

The most concerning health risks of consuming moldy tea are respiratory issues, allergic reactions, and toxicity. The severity of the health risks depends on the individual’s immune system, the type of mold present, and the amount consumed.

Some of the most common health impacts of mold ingestion in tea include throat irritation, coughing, wheezing, stuffy nose, headache, skin irritation, diarrhea, vomiting, and nausea. In severe cases, long-term exposure to mold in tea can result in organ damage. Therefore, it’s essential to avoid drinking moldy tea at all costs.

It’s important to note that mold can grow in tea bags that have been left in a damp environment, such as a kitchen or pantry. To prevent mold growth, it’s recommended to store tea bags in a dry, cool place. Additionally, if you notice any signs of mold on your tea bags, it’s best to dispose of them immediately to avoid any potential health risks.

While some people may be more susceptible to the health risks of moldy tea, it’s important to remember that anyone can be affected. If you experience any symptoms after consuming moldy tea, it’s recommended to seek medical attention right away to prevent any further complications.

Tips for Preventing Mold in Your Tea

It is important to store tea leaves in a dry, cool, and dark environment that is free of moisture and humidity. Never store tea near cooking equipment or in a cabinet that receives direct sunlight. After brewing your tea, ensure that you properly clean and dry your equipment before use. Finally, avoid using old, expired tea and dispose of any tea that has a suspicious odor or appearance.

Another important tip for preventing mold in your tea is to use filtered water. Tap water can contain impurities and chemicals that can affect the taste and quality of your tea. Using filtered water can also help prevent the growth of mold and bacteria in your tea.

In addition, it is recommended to use airtight containers to store your tea. This will help prevent moisture and humidity from getting in and causing mold growth. You can also add a silica gel packet to your tea container to absorb any excess moisture and keep your tea fresh for longer.

Common Types of Mold Found in Tea

The most common varieties of mold that can grow in tea leaves include aspergillus, penicillium, and rhizopus. However, other types of mold can also grow in tea leaves depending on the tea variety, storage environment, and geographical location of the tea leaf production.

Aspergillus is a type of mold that can produce mycotoxins, which are toxic substances that can cause health problems such as respiratory issues and liver damage. Penicillium, on the other hand, is commonly found in blue cheese and can produce penicillin, a type of antibiotic. While the presence of penicillium in tea may not necessarily be harmful, it can affect the taste and quality of the tea.

In addition to mold, tea leaves can also be contaminated with other microorganisms such as bacteria and yeast. These can also affect the taste and quality of the tea, and in some cases, can cause foodborne illnesses. It is important to properly store and handle tea leaves to prevent the growth of these microorganisms and ensure the safety of the tea.

What to Do if You Accidentally Drink Moldy Tea

If you accidentally consume moldy tea, it’s important to act promptly and seek medical help as soon as possible. It’s also essential to abstain from consuming any more tea until you receive medical clearance.

Moldy tea can cause a range of health problems, including allergic reactions, respiratory issues, and even poisoning. Symptoms of moldy tea consumption may include nausea, vomiting, diarrhea, abdominal pain, and difficulty breathing. If you experience any of these symptoms after drinking moldy tea, seek medical attention immediately.

To prevent mold growth in tea, it’s important to store it in a cool, dry place away from sunlight and moisture. It’s also recommended to consume tea within six months of purchase and to avoid drinking tea that has been left out for more than eight hours. Regularly cleaning tea-making equipment, such as teapots and infusers, can also help prevent mold growth.

The Importance of Properly Storing Tea to Avoid Mold

Proper storage practices, particularly keeping tea leaves away from moisture and humidity, is the most effective way to prevent mold growth in tea. Always ensure that tea leaves are kept in an airtight container in a cool, dark environment.

In addition to proper storage, it is also important to regularly check the tea leaves for any signs of mold. If you notice any discoloration or unusual smells, it is best to discard the tea and thoroughly clean the storage container before using it again. Mold can not only affect the taste and quality of the tea, but it can also be harmful to your health if ingested.

How to Clean and Disinfect Your Tea Equipment

After preparing tea, it’s essential to clean and disinfect the utensils and equipment you use. Start by rinsing the utensils and equipment in hot water and then allowing it to dry completely before use.

If tea equipment has come into contact with mold, it’s essential to wash with hot, soapy water and then disinfect the equipment by wiping it down with white vinegar or a commercial disinfectant.

It’s also important to regularly deep clean your tea equipment to prevent the buildup of bacteria and other harmful microorganisms. To do this, you can soak your equipment in a solution of hot water and baking soda for several hours before rinsing and drying thoroughly.

Another tip for keeping your tea equipment clean and fresh is to avoid using abrasive cleaners or scrubbers, as these can scratch the surfaces and create areas where bacteria can grow. Instead, opt for gentle cleaning solutions and soft cloths or sponges to ensure that your equipment stays in top condition.

Alternatives to Throwing Away Moldy Tea

One of the alternatives to throwing away moldy tea is to use it for external purposes such as cleaning your furniture or shoes. You can also use it as a natural fertilizer for your plants, or for dyeing cloth.

Exploring the Link Between Humidity and Mold Growth in Tea

As stated earlier, humidity is one of the main causes of mold growth in tea leaves. High humidity can create the perfect breeding ground for mold in tea leaves. Consequently, tea manufacturers and distributors must maintain specific temperature and humidity levels to ensure that the tea remains fresh, mold-free, and safe to consume.

Debunking Common Myths About Moldy Tea

There are a lot of myths and misconceptions surrounding moldy tea. For example, some people believe that boiling water kills all mold in tea. However, boiling water only kills some types of mold and not the spores.

Another common myth is that tea is naturally resistant to mold since it contains bacteria-fighting ingredients. However, this is not entirely true, and if tea is stored or prepared in the wrong conditions, mold can grow.

The Economic Impact of Mold on the Tea Industry

Mold outbreaks in tea production can have a massive impact on the tea industry both locally and internationally, leading to economic losses and negative impacts on tea producers’ revenue. Thus, it’s crucial to establish appropriate health standards and regulations to ensure that tea products are safe for human consumption.

Safety Regulations for the Production and Sale of Tea Products

Various government health and safety regulations govern the production and sale of tea products. For instance, the FDA has established guidelines to ensure that tea products are fit for human consumption. Furthermore, international regulatory bodies such as the ISO and the WHO have established production, storage, and safety guidelines to ensure the quality and safety of tea products.

An Overview of the Health Benefits and Risks of Drinking Tea

Drinking tea can lead to numerous health benefits, including reducing stress levels, improving heart health, improving mental alertness, and aiding in digestion. However, consumption of moldy tea can lead to severe health risks as earlier discussed. It’s essential to ensure that the tea you consume is free of mold and other harmful contaminants.


In conclusion, moldy tea can be a significant health risk if not identified and handled promptly. We’ve looked at the causes, identification, health risks, prevention, and measures to take if you accidentally drink moldy tea. Always ensure that you store your tea correctly, clean your equipment regularly, and discard tea that has a suspicious appearance or odor. By following these simple tips, you can ensure that you enjoy the numerous health benefits of tea without exposing yourself to health hazards.
