Production of multistrange hadrons is studied in a Statistical Hadronization Model (SHM) inspired largely model independent approach. We find that the yields of all multistrange hadrons available today are 1) compatible with the SHM picture of hadron formation, 2) are well described by current hadronization models in the parameter domain obtained from the other hadron yields, 3) these data strongly disfavor the chemical equilibrium single-freeze-out SHM. We find that particles with small cross-sections are emerging at the same hadronization condition as other particles. This is expected for a fast expanding QGP fireball which under-cool and rapidly breaks apart (hadronizes) near to the lattice derived chiral symmetry restoration temperature.
