*Project Summary





To see what type of bacteria and e-coli grows in
different teas
To see how many coliforms grow from tea samples
Take several different tea samples and run tests
Take a count of how many coliforms were present
at the end of the experiment.
Give data and charts on results
Introduction/Background

My hypothesis is that tea at certain temp. levels
will cause dangerously high levels of bacteria.
 So tests are going to be performed to see what
types of bacteria grows in tea
 “The Centers for Disease Control and Prevention
(CDC), which investigated the reports about iced
tea, explained that theoretically tea could transmit
disease if other bacteria survived the brewing -- a
possibility with some organisms--and if they were
allowed to grow in unrefrigerated tea” (Iced
1996).
Methods & Materials

Streak different tea samples on agar plates
 Coliform count
 Majority of America drinks tea. To better
America as a whole tea samples will be
taken to see what is really in tea
 Data will be recorded in tables and graphs
 This experiment will be administered by Dr.
Goss and myself
Results

I expect to find several different micro organisms
that are in tea. The reason for this is because tea is
exposed to heat for long periods of time.
 I expect to find several different fascinating
organisms
 The benefits of this experiment will better the
knowledge of tea and its content.
Project Timeline

Start date March 14, 2005
*Obtain several tea samples from 5 different restaurants
*Set up several tests( MAC, BAP,TSA, or coliform)
*Take the different results
*Do graphs and numbers
*Etc.

End date March 25, 2005

Budget

The proposed budget for this experiment
will be tea (estimated budget $5.00).
 All other expenses will be covered by Dr.
