Abstract
Because cardiovascular disease incidence has rapidly increased in recent years, people are choosing relatively healthier diets with low animal fat. A transgenic pig with low fat and a high percentage of lean meat was created in 2011; this pig overexpresses the follistatin (FST) gene. To evaluate the safety of lean pork derived from genetically modified (GM) pigs, a subchronic oral toxicity study was conducted using Sprague-Dawley rats. GM pork and non-GM pork were incorporated into the diet at levels of 3.75%, 7.5%, and 15% (w/w), and the main nutrients of the various diets were subsequently balanced. The safety of GM pork was assessed by comparison of the toxicology response variables in Sprague-Dawley rats consuming diets containing GM pork with those consuming non-GM pork. No treatment-related adverse or toxic effects were observed based on an examination of the daily clinical signs, body weight, food consumption, hematology, serum biochemistry, and organ weight or based on gross and histopathological examination. The results demonstrate that GM pork is as safe for consumption as conventional pork.
