The answer
The Coptic Orthodox Church does not follow the customs of differentiating between consumption of clean and unclean food described Leviticus 11. The Holy Book of Acts, Chapter 10, mentions St. Peter having a vision in which he was instructed to no longer keep this specific custom. The apostles in the early Church convened in councils to discuss many issues, especially regarding the Gentiles who were converts, and reached a consensus about what customs to keep and which to discontinue for all the congregations of the Church:"For it seemed good to the Holy Spirit, and to us, to lay upon you no greater burden than these necessary things: that you abstain from things offered to idols, from blood, from things strangled, and from sexual immorality. If you keep yourselves from these, you will do well" (Acts 15:28-29)
