A topological space $X$ is uniformly normal if the family $\mathcal{ U}$ of all symmetric neighborhoods of the diagonal $\Delta \subset X\times X$ forms a uniformity on $X$. A neighborhood of the diagonal is any subset whose interior contains the diagonal. It is proved that the $\Sigma$-product of Lindelof $p$-spaces of countable tightness is uniformly normal.
