    Reference: AQA

    In strong and electromagnetic interactions strangeness is conserved, but the weak interaction can change the strangeness of an individual quark.
    AQA · Classification of particles (study guide)
    In a strong interaction the total strangeness of the reacting particles equals the total strangeness of the products.
    AQA · Classification of particles (study guide)
    Strangeness is conserved in strong and electromagnetic interactions but not in weak decays.
