Deli Turkey Case Study

Decent Essays

Experiment 2 focused primarily on different forms of deli turkey due to the results of high microbial count on the deli turkey sampled in experiment 1. 4 different samples of deli turkey were obtained: first, the same deli turkey sampled in experiment 1 which was considered non-natural sliced turkey from Hannaford, sliced organic deli turkey with no preservatives from Hannaford, non-natural prepackaged turkey from a Lunchables and organic prepackaged turkey with no preservatives from Waterhill. The hypothesis for experiment 2 was that the samples that came in contact with the meat slicer or not prepackaged meat was going to yield the most microbes disregarding whether or not the meat was nitrate free or contained preservatives. To prove or disprove this hypothesis, each sample was put through the dilution process explained in the methods section. Modifications do …show more content…

I comparison to experiment 1, there was much less variation in the types of colonies observed on the plates, most were the same round, yellow colored colonies that varied in size as shown in figure 6. There were approximately 3 colonies throughout all dilutions that contained the mountain like colony that was more popular in the dilution series conducted in experiment 1. Only dilutions 3 and 5 were deemed too many to count. From figure 6, it’s observed that dilution 3 exhibited the same fused together colonies that many of the dilutions in experiment 1 had with more isolation as the dilutions progress. However, dilution 5 appears far different than the other dilutions with very small colonies that are uncharacteristic to this series of dilutions conducted in experiment
