I don't think this is a real concern, for two reasons: first, how should such a "transfer of genes" to another species proceed? This is not how it works.
Secondly, these genes are pretty much self-regulating; they disappear from the population in one generation. They almost certainly won't be in the ecosystem long enough in order to play a role in any improbable scenario.
