When ns was farming up, my mom brewed her iced tea top top the former porch in the sun. The Centers for condition Control and also Prevention (CDC) phone call the tea she made “sun tea.”

In 1996, the CDC placed out a “Memo ~ above Bacterial pollution of Iced Tea.” The memo was addressed come state and territorial epidemiologists, and provided information ~ above iced tea safety and security in response to local and state health department requests because that guidelines ~ above preparing and storing iced tea in a way to minimize bacterial contamination.

Foodborne pathogens have the right to survive in brewed tea, however for tea brewed in ~ an ideal temperature–with water hot enough to kill pathogens–the concern of safety and security is mostly one of warehouse conditions and ensuring the tea dispenser has actually been cleaned and also disinfected before use.

The CDC summarized its result on iced tea safety with the complying with points:

1. Tea is a beverage v little background of an illness transmission. In ~ present, no outbreaks of infection have actually been reported to CDC that were plainly associated through the usage of tea.

You are watching: Why is it possible to see the iced tea in a clear glass pitcher?

2. Tea leaves may be contaminated v coliform bacteria. If iced tea is brewed at inadequate temperatures or in one improperly cleaned urn, or if the is save on computer for as well long, that may thrive coliform bacteria, most frequently Klebsiella and also Enterobacter, and also less frequently E. Coli. In particular, the faucet of iced tea urns may provide a nidus because that bacterial contamination.

3. Food managing errors that lead to the development or the encourage the replication the microbial pathogens in brewed tea could theoretically an outcome in human disease.

4. Impending iced tea at an proper temperature in a completely cleaned urn and also limiting the time held at room temperature prior to serving will minimize the theoretical risk of bacterial contamination.

Recommendations for Iced Tea Safety

* Iced tea sould be brewed at 195 F for 3-5 minutes.

* Iced tea should be stored for no much longer than 8 hours.

* The tea brewer, storage dispenser, and also faucet should be cleaned daily.

The CDC proclaimed that redesigning tea dispensers come be an ext easily dismantled and cleaned could further minimize the theoretical hazard of bacterial contamination of iced tea.

Sun Tea

According come the CDC, “The exercise of making ‘sun tea’ through steeping tea bags in a container of water in the sun may be higher theoretical risk than impending tea at higher temperatures since it provides an atmosphere where bacteria are an ext likely to survive and also multiply.
