Reference: AQA
In strong and electromagnetic interactions strangeness is conserved, but the weak interaction can change the strangeness of an individual quark.
In a strong interaction the total strangeness of the reacting particles equals the total strangeness of the products.
Strangeness is conserved in strong and electromagnetic interactions but not in weak decays.
