The liquid-gas phase transition in strange hadronic matter is reexamined by using the new parameters about the {lambda}-{lambda} interaction deduced from recent observations of the {sub {lambda}}{sub {lambda}}{sup 6}He double hypernucleus. The extended Furnstahl-Serot-Tang model with nucleons and hyperons is utilized. The binodal surface, the limit pressure, the entropy, the specific heat capacity and the caloric curves are addressed. We find that the liquid-gas phase transition can occur more easily in strange hadronic matter with weak Y-Y interaction than that of the strong Y-Y interaction.
