Beleaguered Beef: Guess What's Coming to Dinner?

Objectives/Goals:

The objective was to determine whether or not there is a difference between
naturally grown ground beef
and standard ground beef in terms of antibiotic additives. I hypothesized that
the standard ground beef
would show usage of antibiotic additives while the naturally grown ground beef
would not.

Methods/Materials:

I swabbed five agar dishes with the juice from standard and natural ground beef.
The standard ground beef
types were Porter's Premium and Raley's. The natural ground beef types were
Coleman Natural, Whole
Foods lean, and Whole Foods leanest. Additionally, I used one agar dish as a
control, in which I did not
swab it with the variable. I then incubated all six agar plates over a period of
five days. From the growth
of bacteria on each agar plate, I concluded whether or not antibiotics were
used.

Results:

In terms of percentage of bacterial growth covering the agar plates, the
naturally grown ground beefs
averaged 31 percent of their entire agar plates. Next, the standard ground beefs
averaged 30 percent.
Finally, the control averaged 20 percent. At times the some of the naturally
grown ground beefs cultured
fewer amounts of bacteria than some of the standard ground beefs. I attribute
this to the fact that there is
usually more effective sanitation in natural beef factories than in standard
ones.

Conclusions/Discussion:

My hypothesis was proven correct in that the naturally grown ground beefs
cultured more bacteria
because they had little or no antibiotic additives. Reversely, the standard
ground beefs cultured less
bacteria because of the presence of antibiotic additives. As much research
states, antibiotic additives in
meat are dangerous and should be prohibited. When humans consume this meat they
risk health problems
and possibly even death. My investigation proves that it is much healthier to
eat naturally grown ground
beef than standard ground beef. Therefore this finding could be very benefical
to the public.
