We review the production of strange hadrons in nuclear collisions in which the collision energy pre nucleon is below or just slightly above the threshold for strangeness production. First, a statistical model is formulated in which the exact conservation of strangeness and averaging over impact parameter can properly be handled. The observed data are compared with the predictions of the model and the right amount of underprediction is obtained. Then, kinetic model for hadron production is formulated and constrained by the observed data on kaon production. The yields of Phi and Xi are calculated and compared to the data. Possible effects necessary for the description of the data are discussed.
