What is a list of foods a vegetarian can't eat?

It's up to you. "Vegetarian" means you don't eat meat, but that can be extended to anything that contains animal products.

Please, if you do give up meat, make sure you include fish. The number of people who call themselves vegetarian but still eat fish drives me mad. If you eat no meat other than fish, you are a pescetarian.

I was going to say most cheeses, but was beaten to it. Worcestershire sauce is also not vegetarian.

Right! It's so annoying. Fish IS meat. People are idiots.

Don't forget stock cubes! Bistro is vegetarian x

If you want to be fully vegetarian you need to check the packaging for loads of things. Some stuff you'd think you couldn't have (beef hula hoops and chicken supernoodles) are actually vegetarian and some things you wouldn't expect not to be aren't like some chocolate.

I've given up eating meat for now, still eating fish but am slowly working toward removing other animal containing products from my diet.

For the semantics argument, I don't call myself anything, I just don't eat meat.

I'm thinking about becoming a vegetarian, but I'm not sure what foods(besides meat) that I can't eat.

Any particular reason?
Only because if you are doing it for health then you might want to stick to lean meats in smaller portions (& only a few times per week) and still include oily fish a couple of times a week. You could have a 'meat reduced' diet, upping your fruits/veggies/pulses/grains/nuts & seeds in your diet.
If you are have a moral/ethical/food chain energy efficiency reason, then you might want to cut out all meats (including fish - they do have faces and mothers after all) and then think about what some of the posts have mentioned above about products that contain rennet & gelatine etc.
Or, if you just don't like the taste - then meat gone, but the by-products may not be such an issue.
All depends really. Good luck though!

I understand that if you eat fish and no other meat that you are not considered a vegetarian but instead a pescitarian, however, in the Canadian Food Guide, fish is considered a meat alternative, the same category as nuts, peanut butter, eggs, beans and the like of. It's not considered meat.

More often than not, cheeses are made with beef rennet; enzymes extracted from linings of cow stomachs. Vegetable rennet also exists, but it's used less often (although some brands like Cabot only use vegetable).

I believe much of the rennet is now recombinant, so no calf killing.

A vegetarian is someone who lives on a diet of grains, pulses, nuts, seeds, vegetables and fruits with, or without, the use of dairy products and eggs.

Or

A vegetarian does not eat meat, poultry, game, fish, shellfish or crustacea, or by-products of slaughter.

There are different degrees of vegetarianism which may be what causes confusion with caterers. The four most common forms of vegetarianism are:

Lacto-ovo-vegetarian. Eats both dairy products and eggs. This is the most common type of vegetarian diet.
Lacto-vegetarian. Eats dairy products but not eggs.
Ovo-vegetarian. Eats eggs but not dairy products.
Vegan. Does not eat dairy products, eggs, or any other animal product.

Eggs: Many lacto-ovo vegetarians will only eat free-range eggs. This is because of welfare objections to the intensive farming of hens. Through its Vegetarian Society Approved trade mark, the Vegetarian Society only endorses products containing free-range eggs.
