Advancements in metagenomic technology have been a boon to research but may encroach on people’s expectation of privacy. A staggering amount of information can be derived from the cells we leave behind on everyday surfaces, and our ability to interpret this information to learn about YOU will only grow with time. While these advancements are not likely to ever be 100% accurate, they present a potential avenue for discrimination. Genetic privacy is not a new concept, and in the US and elsewhere, there are laws protecting people from some discrimination based on genomic-derived data, but metagenomics is not covered by the existing laws and requires its own ethical and legal scrutiny. Our world is rapidly becoming one with ubiquitous genetic, molecular, and data profiling. In that world, privacy will be difficult to protect unless statutes and laws are brought up to date with the advancement in biotechnology. To do that, however, there should be an awareness and a widespread discussion about molecular privacy and rights.
