Genomic Standards Consortium package extension for reporting of measurements and observations obtained from the environment where the sample was obtained. By choosing the environmental package, a selection of fields can be made from a relevant subsets of the GSC terms. This package is a combination of the four food extensions (MIxS-food-animal and animal feed, MIxS-food-farm environment, MIxS-food-food production facility, MIxS-food-human foods).
