We find that for a large enough strange quark mass, m{sub s}{sup 2}/4{mu}{delta}>2/3(1-0.023) ({mu} is the quark number chemical potential, {delta} is the superconducting gap), the kaon condensed color flavor locked (CFL) phase of asymptotically dense strongly interacting 3 flavor quark matter is unstable with respect to spontaneous generation of currents of Nambu Goldstone bosons due to spontaneous breaking of baryon number symmetry and hypercharge symmetry in the CFLK{sup 0} ground state. The total baryon and hypercharge currents vanish in the ground state. We find that CFLK{sup 0} and the new state are separated by a first order phase transition. The result is derived in the mean field approximation of high density effective theory with electromagnetic interactions turned off.
