Here are some useful sites:

www.theisraelofgodrc.com : These people have done a lot of work at putting together a list of foods that do and do not contain unclean meats. There are a lot of things you’d never even think about being unclean. This is definitely a good site to bookmark although it is a little difficult to navigate.

http://www.mazornet.com/jewishcl/Kosher/kosherorgs.htm : Here’s a list of some common kosher symbols. These can be very helpful to know when going through your local grocery store. Look for them not just on food containers, but dish soap and laundry detergent too!

http://http://www.vegsoc.org/page.aspx?pid=729 : Lists some common food ingredients that you may not know are from animal sources. Note, that it’s from a vegetarian slant, so some items listed may be clean according to Biblical standards.

http://www.caringconsumer.com/page/CompaniesDont.pdf : Lists companies that don’t test their products on animals. Note: if the company doesn’t have an (*) next to it, their products may still contain animal derived ingredients.

http://www.vnv.org.au/site/index.php?option=com_content&task=view&id=87&Itemid=133 : Believe it or not, your alcohol may be unclean! This site is from a vegetarian slant, but if it’s marked with an “NS”, it’s likely to be unclean due to direct ingredients or being refined with unclean ingredients (such as isinglass – gelatin from the unclean sturgeon fish).

http://www.happycow.net/north_america/usa/ : Lists restaurants and grocery stores that are vegetarian only or have vegetarian friendly offerings.
