Engine ingestion standards

How big living bodies can be ingested by an engine so that the plane remains?

The biggest flying birds include bustards, mute swans and I think turkeys, having MTOW in the region of 30-40 pounds. Are the engines built and tested so that ingesting them can be dealt with?

At least birds seriously bigger than that cannot fly and therefore can only be ingested on ground. As can other living bodies. An Air France jet recently met a cow, but I think did not ingest the cow. Some years ago, a ground worker in some airport, I think a Chinese, was ingested. He died, as intended – has anyone heard what was left of the engine and the rest of the plane?
