Is my work in shipping expired foodstuffs unlawful, and how can I rectify my mistake?

It is impermissible to sell expired food products, except under two conditions: that their consumption does not cause harm, and that the buyer is aware of their expired status.

If the company sells to retail stores, it is also stipulated that it must be highly probable that the store will disclose the expiration to the buyer.

If these conditions are met, then there is no objection to the work. Otherwise, it is impermissible to ship these products, so as not to assist in sin.
