The FDA Foods Whole Genome Sequencing Staff is coordinating efforts by public health officials to sequence pathogens collected from foodborne outbreaks, contaminated food products and environmental sources. The genome sequences are archived in an open-access genomic reference database called GenomeTrakr, that can be used: to find the contamination sources of current and future outbreaks; to better understand the environmental conditions associated with the contamination of agricultural products; and to help develop new rapid methods and culture independent tests.
