Plain rusk in a small amount is generally low risk, but South African rusk recipes commonly include raisins or currants, which are toxic — always check before sharing.
Rusks themselves (a dried, twice-baked bread) carry no unique toxicity concern, but they're a genuinely common source of accidental raisin exposure in South African households given how often raisins appear in traditional rusk recipes. This is a real, easy-to-miss risk worth naming explicitly.
