We have spoken to the manufacturers of Tetley tea bags following concerns about the labelling on some of their green tea bags stating that they may contain gluten.

The manufacturer has told us that there is a risk of contamination with wheat gluten during production. They have labelled these products as a precautionary measure due to a risk of contamination in the tea bag. Any trace of gluten in the tea bag will be diluted in the brewed tea, so the level of gluten in the tea you are drinking will be well within the safe level for people with coeliac disease (20 parts per million or less).

Tetley are investigating the issue and trying to remove the risk of contamination. Once this is done they plan to remove the statement from the packaging, so you may see a mixture of packs on store shelves with and without the warning.
