We consider the quark-mass dependence of the baryon octet and decuplet ground state masses. It is predicted that QCD dynamics implies a first order transition when increasing the strange quark mass from its chiral limit towards its physical value. Our claim relies on a global fit to the available QCD lattice data on such baryon masses. Quantitative results based on an application of the chiral SU(3) Lagrangian at N
LO are discussed. We predict an anomalous sector of QCD where stable baryonic matter would be composed of 
or 
particles rather than nucleons and anti-nucleons.
