Abstract
Safety assessment must be conducted before the commercial release of transgenic silkworms. This study was conducted to assess the potential of transferring transgenic DNA from silkworms to other organisms. One hundred hatched male chickens were evenly assigned into 4 groups (T1-4). Groups T1-3 were fed transgenic silkworms P3+5UI with enhanced green fluorescent protein DNA (EGFP) inserted, A4SOR with superoxide reductase DNA (SOR) inserted, and normal silkworm, respectively. Each chicken was fed one silkworm larva every day for 3 weeks. T4 was the normal feeding control. Twenty chickens were randomly selected from each treatment for sacrifice at 22 days of age. The serum was collected individually for biochemical examination, revealing no difference in the analyzed serum parameters between T4 and T1-3. DNA from the duodenum, jejunum, ileum, liver, kidney, and jejunal digesta was extracted for PCR analysis of EGFP, SOR, silkworm housekeeping gene TIF-4A, and chicken ovalbumin gene. No transgenic DNA or TIF-4A was detected in the digesta and tissues of chickens. The same results were observed in chicken upon increasing the amount and frequency of feeding transgenic silkworms, suggesting that the transgenic DNA from silkworms was degraded in the digestive tract and not transferred into the tissues of chicken. This study revealed that transferr recombinant DNA from transgenic silkworm to another organism is unlikely.

Abstract
A large share of genetically modified (GM) crops grown worldwide is processed into livestock feed. Feed safety of GM crops is primarily based on compositional equivalence with near-isogenic cultivars and experimental trials in rodents. However, feeding studies in target animals add to the evaluation of GM crops with respect to animal health. This review aimed to evaluate the possible health effects of feeding GM crops to livestock by reviewing scientific publications on experimental studies in ruminants, pigs, and poultry in which at least one of the following health parameters was investigated: body condition score, organ weight, haematology, serum biochemistry, histopathology, clinical examination, immune response, or gastrointestinal microbiota. In most experiments, either Bt (Bacillus thuringiensis) maize, Roundup Ready (RR) soybean, or both were fed to livestock animals. Significant differences (P<0.05) in health parameters were most often observed when animals were fed Bt maize, although most effects measured were unlikely to be of biological significance and were within normal biological ranges. Health effects of RR soybean were only observed in one experimental study with broilers. Based on this literature review, we conclude that there is no clear evidence that feed composed of first generation GM crops has adverse effects on animal health.

Abstract
Modern agriculture provides the potential for sustainable feeding of the world's increasing population. Up to the present moment, genetically modified (GM) products have enabled increased yields and reduced pesticide usage. Nevertheless, GM products are controversial amongst policy makers, scientists and the consumers, regarding their possible environmental, ecological, and health risks. Scientific-and-political debates can even influence legislation and prospective risk assessment procedure. Currently, the scientifically-assessed direct hazardous impacts of GM food and feed on fauna and flora are conflicting; indeed, a review of literature available data provides some evidence of GM environmental and health risks. Although the consequences of gene flow and risks to biodiversity are debatable. Risks to the environment and ecosystems can exist, such as the evolution of weed herbicide resistance during GM cultivation. A matter of high importance is to provide precise knowledge and adequate current information to regulatory agencies, governments, policy makers, researchers, and commercial GMO-releasing companies to enable them to thoroughly investigate the possible risks.

Domingo JL. Safety assessment of GM plants: An updated review of the scientific literature. Food Chem Toxicol 2016; 95:12-8.

Abstract
In a wide revision of the literature conducted in 2000, I noted that the information in scientific journals on the safety of genetically modified (GM) foods in general, and GM plants in particular, was scarce. Of course, it was not sufficient to guarantee that the consumption of these products should not mean risks for the health of the consumers. Because of the scientific interest in GM organisms (GMOs), as well as the great concern that the consumption of GM foods/plants has raised in a number of countries, I conducted two subsequent revisions (2007 and 2011) on the adverse/toxic effects of GM plants. In the present review, I have updated the information on the potential adverse health effects of GM plants consumed as food and/or feed. With only a few exceptions, the reported studies in the last six years show rather similar conclusions; that is to say, the assessed GM soybeans, rice, corn/maize and wheat would be as safe as the parental species of these plants. However, in spite of the notable increase in the available information, studies on the long-term health effects of GM plants, including tests of mutagenicity, teratogenicity and carcinogenicity seem to be still clearly necessary.
