Cargo lost from critical hits isn't necessarily destroyed in all cases. It's conceivable that cargo that was contained in specifically armoured and secure containers might have survived, maybe sent drifting away from the ship in the debris.
Haven't we all played Elite?
For that matter, short of a 100% cargo loss, it's up to the Referee exactly what survived. Fragile cargo such as livestock might all have been lost, even with minor criticals. Robust, bulk cargo like ore may have mostly survived being sent into space, but might be hard to gather back up.
