Does "to get a little gross" mean "to be a little rude"?

Context:

In fact, the potential side effects of non-GM food is, very explicitly, what the Chinese research team showed: that of the millions of miRNAs we eat every day, at least a few make it from our stomachs into our blood, and that a specific one from ordinary rice can change the expression of genes in mice. So if miRNAs are dangerous – guess what? – you’re already ingesting them every time you eat. And, to get a little gross, let’s be clear: when we eat something, we don’t just ingest the miRNAs from the species we intentionally eat. Did you know, for example, that foods you eat http://www.fda.gov/food/guidancecomplianceregulatoryinformation/guidancedocuments/sanitation/ucm056174.htm? All of those bits of organisms which we inadvertently eat have DNA, and – you guessed it! – miRNAs, too. If miRNAs are so dangerous, we would never have been able to eat anything previously alive in the first place.
