Answer:
In a word, no. The Talmud strongly urges against combining these two food groups due to “danger” more hazardous than the mere punishment for violating this prohibition. Turns out this was no idle threat. Back in Talmudic days, the oils of fish and meat mixed together were reported to have caused illness, or at the very least that eternal Jewish plight known as indigestion. Blame it on antiquated methods of food preservation, or even the lack of proper antacids. Now we have Alka Seltzer to “plop, plop, fizz, fizz” our gastrointestinal problems away. Nevertheless, because it was established as a health concern back then, the practice is still prohibited. These days, there is no penalty for violation, and who knows what the punishment might have been back then? The point was–is–to obey G-d’s laws to the best of our abilities. Therefore, thou shalt noy not mix surf with turf. Still, no need to wait for any particular period of time in between courses the way you do with meat and dairy. A simple drink of water, a taste of sorbet or mint to cleanse the palate, or even a piece of bread in between can do the trick. In addition, arming yourself with a fish fork is a great defense. This doesn’t mean you can’t eat fish with a meat fork. You just can’t go from gefilte fish to brisket in one fell swoop. And you probably wouldn’t want to. In truth, you can lick the fork in between–it just wouldn’t be polite. And since Kosher literally means “fit”, you wouldn’t exactly be living up to expectation, now would you?
