Technicolor theories predict the existence of particles (technibaryons) about a thousand times heavier than the proton. A large number of technibaryons should have been present in the early Universe. Here I explore the cosmological effects of remnant technibaryons that decay after electron-positron annihilation. Strong limits on the lifetimes of these particles are imposed with very little model dependence. Technibaryons decaying when the cosmic temperature is about 1 eV may appreciably distort the microwave background. I discuss the possibility of technibaryons accounting for recently observed distortions in the submillimeter regime.
