Abstract Genetically modified food animals (GMFAs) are needed to address early the cumulative effects of livestock production on the environment and to accommodate future food demands. In 2020 China and the U.S., the world's two largest economies, embarked on regulatory reforms to boost the commercialization of such animals. However, gaining social acceptance of GMFAs for commercialization remains a global challenge. We propose a framework that focuses on social license for commercialization of GMFAs by defining four classes of improvement using precision genetics: 1) animals equivalent to natural variation to obtain the improved effect of cross-breeding (ENV); 2) animals with an inactivated gene that could occur via natural mutation (ENC-); 3) animals harboring a natural genetic sequence isolated from another species (ENC+); and 4) animals with synthetic sequences encoding novel genes (BNE). Our approach can guide regulators and the public to support orderly commercialization of genetically modified food animals.

Biosafety of genetically modified organisms (GMOs) and their derivatives is still a major topic in the agenda of government and societies worldwide. The aim of this review is to bring into light that data that supported the decision taken back in 1998 as an exercise to stimulate criticism from the scientific community for upcoming discussions and to avoid emotional and senseless arguments that could jeopardize future development in the field. It must be emphasized that Roundup Ready® soybean is just one example of how biotechnology can bring in significant advances for society, not only through increased productivity, but also with beneficial environmental impact, thereby allowing more rational use of agricultural pesticides for improvement of the soil conditions. The adoption of agricultural practices with higher yield will also allow better distribution of income among small farmers. New species of genetically modified plants will soon be available and society should be capable of making decisions in an objective and well-informed manner, through collegiate bodies that are qualified in all aspects of biosafety and environmental impact.

Epiphytic LAB, e.g., lactobacilli, lactococci, enterococci, pediococci, streptococci, and leuconostocs, play a major role in silage fermentation. Their numbers and populations have become a concern in predicting the adequacy of silage fermentation and in determining whether or not to apply a bacterial inoculant (Bolsen et al, 1989). Epiphytic LAB counts are usually low and variable on silage crops (Lin et al, 1991), and increases in the LAB counts usually occur coincident to the chopping process. Only limited information is available concerning the succession of epiphytic LAB species during the ensiling period of alfalfa (Medicago sativaL.) and maize (Zea mays L.), the two major silage crops in North America. The present studies investigated the epiphytic LAB succession during the pre-ensiling and ensiling periods for two cuttings of alfalfa, each harvested at three stages of maturity, and three whole-plant maize hybrids.A second-year stand of alfalfa was harvested at the 2nd and 4th cuttings and at the late-bud, 10% bloom, and 50% bloom stages of maturity within each cutting in 1989. Following mowing, the alfalfa was wilted in the windrow for 5 to 6 hours prior to precision chopping.

Abstract Familiarity based approval of the newly developed GM cereal events is based upon the stable and safe consumption of conventional grains. The level of concentrations of mycotoxins and biomolecules establishes the criteria for premarket evaluation of genetically modified cereals e.g. MON 810 maize. The objective of the present study was to comparatively evaluate food biosafety of the conventional and GM maize. Grain samples from the harvest lot of 10 maize hybrids in the year 2011 were collected arbitrarily. Well ground and homogenized samples were analysed for the deoxynivalenol (DON) and ochratoxin A (OTA) mycotoxins. Contamination rates and levels of DON and OTA were low and did not exceed the maximum levels, indicating their possible safe use as food and feed under the EC regulation 1881/2006.The samples were further analysed for the possible effect of mycotoxin concentration upon that of starch and proteins. The study reveals the absence of any negative impact of the presence of mycotoxins upon these biomolecules as their concentrations lie within the normal range. A comparative review of data for the mycotoxins in conventional maize grains invalidate the argument from the producers of GM maize hybrids that conventional hybrids are inferior for food biosafety with respect to mycotoxins.
