Strange matter, a stable form of quark matter containing a large fraction of strange quarks, may have been copiously produced when the Universe had a temperature of \ensuremath{\sim}100 MeV. We study the evaporation of lumps of strange matter as the Universe cooled to 1 MeV. Only lumps with baryon number larger than \ensuremath{\sim}${10}^{52}$ could survive. This places a severe restriction on scenarios for strange-matter production.
