The kitchen sink is the place where you rinse materials which may have touched raw meat...My roommate had a worse time with catching salmonella from undercooked chicken his mom made, lol. Never an issue handling my reptiles or helping with cage cleaning.
For a quick rinse and water change I just use the kitchen sink for mine.
If it's something where there's poop and such involved, I pour it down the toilet, scrub it out with some sanitizer, flush that too and the after rinse happens in either my own bathroom sink or the side yard
Tub and cage cleaning happens in the side yard.
Unless you have roommates that are immunocompromised there shouldn't be any real problems.
My second roomie and I both have immune disorders and neither of us have issues because hand wash protocols and if there is a need for me to do some heavy cleaning in the sink, bleach is the followup as well.
