Do snakes eat steak?
the only snakes that would likely try and eat a calf would be reticulated pythons and anacondas, so they could eat the type of meat. however, no snakes can eat the meat that's sold as steaks for people in grocery stores as these often have extra stuff added to help preserve the meat or its color.
If you mean "constantly" as in "continually eat raw steak without stopping", you'll probably get stomach ache or vomit at some stage. If you mean "constantly" as in "I always eat my steak raw", there are actually many steak dishes that use raw steak; Steak Tartare or steak carpaccio for example. As long as the steak is very fresh and from a reputable source, there is no reason not to eat steak raw.
