This contribution summarises the recent results of the NA61/SHINE experiment on strangeness production in the system size dependence will be presented. Preliminary results on K+ and K− production in central Ar+Sc collisions will be discussed within the scope of the onset of deconfinement. Furthermore, final results on Ξ− and Ξ+ hyperon production, as well as preliminary spectra of Ξ0 (1530) and Ξ0-bar (1530) produced in p+p interactions at 158 GeV/c will be reported
along with results on an experimental search for pentaquarks.
