The Wikipedia page on surface energy gives values in the hundreds to thousands of mJ/m^2 for solids. I haven't a clue where meat and bone would fall in that table, and I haven't been able to find out with five minutes of Google, but even if we assume they're on the high side we're not talking particularly high total energies.

(Tangentially, "surface energy of meat" is one of the better phrases I've Googled lately.)
