Using the natural rays of the sun to make tea is fun and popular in the summer. However, using such a method to make tea is highly discouraged. Sun tea is the perfect medium for bacteria to grow. If the sun tea has a thick or syrupy appearance, it may be due to the presence of a ropy bacteria called Alcaligenes viscolactis. Ropy bacteria are commonly found in soil and water.
Several years ago in Ohio and Washington, several people became ill after drinking tainted ice tea. In Washington it was determined that the tea had been made with tap water only heated to 130 degrees Fahrenheit and left to sit at room temperature for more than 24 hours. As a result, the Centers for Disease Control and the National Tea Association recommend the following when making tea.
