Are Tea Bags Safe
Tea bags are safe to drink tea from. Organic teabags are made from 100% natural materials such as bamboo, corn, and cotton. These products are completely safe and non-toxic. Tea bags made from paper could potentially harbor bacteria. Tea bags made of plastic could leach harmful chemicals and nano plastic particles into your drink.
What new study shows Share on Pinterest Laura Hernandez, a doctoral candidate at McGill University in Montreal, has been looking into the teabag used in research about microplastics in school. Beware, you may be drinking microplastics, and it is all thanks to a plastic teabag, according to new research. Researchers from McGill University tested four popular brands of tea sold in grocery stores, and found that one single plastic teabag could leak 11.6 billion microplastics and 3.1 billion nanoplastic particles into your water.

That is not the only issue, a recent study by McGill University Canada has also found that certain types of tea bags are leaching millions of particles of plastic into our beverages, not just from the sealed plastic, but also from the bags themselves. Scientists found that one plastic tea bag released about 11.6 billion microplastics and 3.1 billion smaller nanoplastic particles into a cup. These microplastics are found in many foods and beverages, including water bottles, but this study found the levels released from a plastic tea bag were thousands times higher than those from other products. Canadian researchers published the study in the Journal of Environmental Science & Technology, published by the American Chemical Society, that found that soaking a single plastic tea bag for one brew at the steeping temperature released approximately 11.6 billion tiny particles known as microplastics, and 3.1 billion nanoplastics, in every cup (source).

| The main benefit of tea bags is that they are convenient | Tea bags contain chemicals and plastics that are toxic to our bodies |
| No mess | Disposable items, like tea bags, has detrimental effects on the environment |
A Canadian team found that steeping a single plastic tea bag at brewing temperature 95degC releases around 11.6 billion microplastics — microscopic pieces of plastic ranging from 100 nanometres to 5 millimetres – in a single cup. Getty Images Tea from plastic bags may release billions of microplastics into a hot cup of tea, researchers said. Plastic tea bags, while looking better, contain plastics such as PVC or nylon, which can also leak chemicals if they are crushed. Paper tea bags may pose problems due to a chemical called epichlorohydrin, used to prevent bags from breaking.
Remember, even paper tea bags usually have a tiny bit of plastic in them, so you need to have a plan to use them safely as well. If you only really like to make tea from bags, seek out brands that do not use plastic in their tea bags. Many of us are aware that using disposable plastic has serious ecological consequences, but we tend to discount teabags since tea is naturally occurring and is supposed to decompose easily. You would think it would be simple to make the switch to non-plastic tea bags, but many tea manufacturers have protested that it will be too expensive to adopt a plastic-free bag.
It is possible to make tea bags a disposable plastic, and then, after every bag is discarded, tea rots in approximately 6 months, but it can take innumerable years for a bag to decompose. To ensure that Tea bags can seal up and retain their shape when placed in a heated liquid, it is necessary to add a plastic polymer, which is polypropylene. Indirect Additives (plasticizers or chemicals used in teabag processing) — Chemicals found within the bags may leak out to your tea as it sits inside the hot water. Bleach, glue, microplastics – Bleach is something that you are drinking when steeping your tea in regular paper, plastic, or nylon teabags.

Drinking tea from paper, plastic, and nylon tea bags may lead to behavior defects, developmental defects, and reproductive health problems. A seemingly innocuous cup of tea may increase such plastic consumption and lead to lasting health defects. Even if you throw any used tea bags into your garbage bin or compost pile, this will still result in plastic contamination because not all will break down.
Leakage is associated with tea bags, in which the actual bag itself is made from a plastic material, rather than a paper bag, which is more common. How tea bags are made differs depending on the brand, but according to The Guardian, around 70-80 percent of bags are made of compostable paper, with the remaining 20-30 percent made from heat-resistant polypropylene. The Canadian Tea and Herbal Society told CBC News in a statement that the materials used in bags of various brands, PET (polyethylene terephthalate, found in plastic beverage bottles) and nylon (used in many bags and pouches), are considered safe to be used with hot foods and beverages. Lipton Tea, for example, assured consumers its PET-made pyramid tea bags are the same type of food-grade material as transparent bottles for water and fruit juices, and…are microwave-safe.
Country Livings investigation shows Twinings claims their range of loose leaf pyramid tea bags contains no plastics and is completely biodegradable. Their standard square tea bags — used for teas like Earl Grey, English Breakfast, and Green Tea — are heated sealed, meaning that they apply a thin polypropylene film to bond two sides together.
Using this means Pukka Herb Tea does not have to use polypropylene to keep our teabags together, and our teabags are free from plastic. Researchers removed tea as it contained oils which made microplastics difficult to see afterward. After researchers soaked the empty plastic teabags, researchers analysed them using electron microscopy, and were shocked at what they saw.
Researchers conducted an initial study where they exposed water fleas – small freshwater animals that are not related in any way to prawns – to microplastics in teabags that were similar to their feeding size. Water fleas – small freshwater animals that are not related in any way to prawns. The researchers counted microparticles by cutting the tea bags, removing the tea, washing away any pieces that may have escaped when cutting, then steeping the bags in distilled water at 95C. The researchers then took a sample, allowed the water to evaporate, counted the plastic particles with an electron microscope, and extrapolated the number into a single cup. The researchers also repeated the experiment with the bags not cut, which still contained the tea, to ensure cutting did not result in shedding from the bags, and with the tea leaves, which confirmed the uncut bags did shedding the microplastics too (though these were harder to count), and with the tea leaves, which confirmed the microplastics did not originate in the tea. To check for the potential toxicities of particles released from plastic tea bags, Tufenkji and colleagues exposed fleas in water at 95degC.
Why should you never squeeze a tea bag?
Tannic acid concentrations are significantly higher in the liquid that is confined inside the tea bag than in the fluid that can be allowed to steep without the bag. You accidentally release these tannic acids into your tea by pressing the tea bag, which results in a cup of tea that is much more bitter, sour, and acidic.
What water is best for tea?
Water from the faucet Filtered tap water is typically the best choice for making tea, with the exception of good-quality bottled spring water and fresh mountain stream water. It might not even be necessary to filter certain neutral-tasting tap water. For the best-tasting tea, hard water should always be filtered.
Should you leave your tea bag in or take it out?
You should leave the bag in the pot once you’ve poured yourself a cup. Put the bag in the cup right away if it has been served with hot water already in it. After three to five minutes of steeping, remove the bag with your spoon, hold it over the cup to allow the liquid to drain, and then set the bag down on your saucer.
