The Safety of Cloned Animal Products

Your name Here

INTRODUCTION

The first in the long line of successfully cloned animals was a sheep named Dolly in 1997 . The method used in cloning Dolly marks a revolution in the cloning technology . The method called Somatic cell nuclear transfer (SCNT ) allows Biologists to work with thousands of eggs removed from an animal 's ovary at one time and thousands of nuclei taken from cell lines cultivated in the laboratory , and thus conceivably produce thousands of clones from a single animal (Fernandez

Sundlof , 2002 br

. 5 . Since then , rapid advancements in the cloning technology have made it commercially feasible to clone animals for food production

Then on Dec . 28 , 2006 the U .S . Food and Drug Administration released a risk assessment and management plan which preliminarily concluded that food derived from cloned animals is safe to eat . This triggered widespread criticism from the Humane Society of United States and other consumer protection organizations . Their concerns include the ethical issues and the safety of cloned animal products

STATEMENT OF THE PROBLEM

The purpose of this thesis is to analyze studies conducted to ensure the safety of cloned animal products . This study also looks at the concerns raised by consumers and research organizations regarding the safety of clone animal products . From these studies and concerns , the thesis aims to produce a conclusion of whether cloned animal products are safe for food consumption . The thesis aims to answer the following questions

What are the strong evidences available that suggests cloned animal products do not pose health hazards to consumers

What are the concerns raised by consumers and other research organizations regarding the safety

Is there enough evidence to disprove the concerns regarding the safety of cloned animal products

ANALYSIS OF DATA

Overview of the Somatic Cell Nuclear Transfer (SCNT

SCNT is an asexual form of reproduction where a differentiated somatic cell (a non-germ line cell from an existing animal ) is introduced to an otzcyte (a cell that is the immediate precursor of a mature egg ) that has had its nucleus (and thus its genome ) removed , and then , following some manipulations , is induced to start replicating (FDA Risk Assessment , 2007 ,

.38 . This is the fusion of nucleus from a differentiated adult animal cell and an unfertilized egg with its own nucleus removed . Even if the new nucleus already contains all the genetic material to create the clone but it cannot grow an embryo until the egg cell behaves like a fertilized egg . This then requires biologists to reprogram the new egg so that it will behave as if it has been fertilized . If the process is successful , the dividing cell is implanted into a female animal . From this time on , the implanted cell develops as if it was a normal egg embryo . It grows inside the womb of the female animal and is delivered just like any new born
