Recent Results on Strangeness Production from CERN Experiment NA49

New results from NA49 on the production of strangeness in elementary and nuclear reactions are presented. New measurements of charged kaon and pion production have been obtained from 40 AGeV Pb+Pb collisions. The evolution of strange meson yields in nucleus-nucleus interactions is studied as a function of collision energy and system size. Cascade baryon yields are presented for a wide range of hadronic interactions including first measurements in p+p and centrality controlled p+Pb collisions.
