"While the previously mentioned conditions would force a formerly kosher animal to become terefah, there are other circumstances in which animals can be non-kosher. Both shellfish and pork are considered to be terefah at all time. However, improperly slaughtered animals also become terefah, as well as animals who have been properly slaughtered but upon inspection are diseased or malformed"
This is not true, exactly. Shellfish and pork are tameiot. And improperly slaughtered animals are call nebhelah, but colloquially, all three words are often used interchangeably. 18.104.22.168 (talk) 01:46, 12 February 2013 (UTC)
Bad idea to merge this article with "Treif": "Treif" is a slang word used by non-professionals, or by professionals in a non-professional context, to refer to ANY type of non-kosher food. "Terefah" is a legitimate Hebrew technical term for a specific set of conditions that render a specific sub-set of food a specific form non-kosher status, with its own specifc ruleset. — Preceding unsigned comment added by Boruch Baum (talk • contribs) 12:37, 6 September 2015 (UTC)
