Anything that suffers and dies instead of us is Christ; if they didn't kill birds and fish they would have killed us. The animals die that we may live, they are substitute people, hunters in the fall killing the deer, that is Christ also. And we eat them, out of cans or otherwise; we are eaters of death, dead Christ-flesh resurrecting inside us, granting us life. Canned Spam, canned Jesus, even the plants must be Christ.
