Do you stay away from steak tartare and kitfo, since the raw beef is seasoned?

I don't know what kitfo is. I think I may have had steak tartare, but I'm not fond of having lots of seasoning on my raw foods. Generally speaking, though, I assume that if a restaurant is serving a raw dish, they have every incentive to make sure that the food in question is fresh and unspoiled. (As a result, raw dishes are often among a restaurant's most expensive things to eat.)

I don't know to what extent seasoning would interfere with freshness detection in general. I rarely seasoned any raw meat with anything stronger than soy sauce or ponzu sauce, and usually only part of any given bite.
