It is edible but not recommended.

According to the inquiry, Dr. Bohe learned that it is not recommended to eat leftover rice soaked in tea. First of all, leftovers can easily cause food poisoning, leading to symptoms such as nausea, vomiting, abdominal pain, diarrhea, and even shock. Secondly, the nutrients in the leftovers have been lost, and the nitrite content will increase, increasing the risk of cancer. Finally, chazuke rice contains a lot of water, which will dilute gastric juice, prevent nutrients from being fully absorbed, and increase the burden on the gastrointestinal tract. In the long run, people are prone to stomach problems. Therefore, it is recommended not to eat leftover rice made with tea.

Chazuke rice refers to the use of tea to soak rice. In southern China, hot tea is usually used to make cold rice, which is Chazuke rice. It is usually soaked with rice, salt, prunes, seaweed and other ingredients. Easy to make and simple to use.
