Dairy and meat.
Dairy with meat.
The Torah specifically forbids cooking a kid (baby goat) in its mother's milk. Now, this is obviously a very specific guideline, so why don't Jews combine any dairy and meat? The reason for this expansion on the core guideline is so that no one accidentally violates it or appears to violate it. As a result, the halakha (law) doesn't permit the mixing of any dairy and meat. Additionally, although meat and fish can be eating during the same meal, they cannot be served or eaten on the same plate. There are also some groups that do not combine dairy and fish.
Jews do not eat pork, and they do not eat meat and dairy in the same meal. There are also guidelines for specific holidays, like no yeast on Passover and fasting on Yom Kippur.
Appetizers that people who kosher won't eat would contain the following:Appetizers that have any type of shellfish in them (say no to crab cakes and shrimp cocktail).Anything made with non-kosher meat (beef/lamb/etc that didn't come from kosher slaughtered and pepared animals or meat from any animal that isn't kosher which includes rabbit, pork, amphibians, etc)Anything made with a combination of dairy and meat (even if said dairy and meat were kosher, it is not kosher to combine the two in any way)Anything made with a combination of fish and meat (although fish is pareve (neutral), the tradition is to not eat meat and fish on the same plate)Additionally, what is being served with the rest of the meal will determine what will be served as the appetizer. Due to the prohibition against combining dairy and meat, if the rest of the meal will be meat, then the appetizer cannot be dairy and vice versa.(see answer.com below and related link)
Jews consider dairy products kosher as long as they are not from forbidden animals or nothing is added to the product to render it non-kosher, such as rennet in cheese. Additionally, some Jews will only use products labeled 'chalav Yisroel', these are dairy items that have Jews directly involved in their production.

The letter P in a circle on food means "Parve", which indicates #1, the food is Kosher, and #2, that it has neither dairy nor meat products in it. This is important information for people who keep kosher as they do not eat meals where dairy ingredients and meat are served at the same time. Parve food or ingredients can be eaten at either a dairy-based or milk-based meal.
Jews eat lots of dairy and fruit dishes. Cheesecake, for example, is a very popular dish on Shavuot (also known as Pentecost or Shavuot), and many cheesecakes have fruit topping. The big restriction is that Jewish tradition forbids eating dairy foods at the same time as meat or too soon after a meat meal. So, after eating a corned-beef sandwich or a good beef brisket, an observant Jew will not accept a dairy dessert.
Bottom line: As long as the meat and dairy do not have contact with one another, they can be in the same cart. (I.E. This applies to canned meats and canned dairy products.) If a piece of meat is badly wrapped and juices are spilling out, all dairy products are considered treif. However, there are some more stringent groups that will shop separately for meat and dairy. The real issues between meat and dairy is long-term storage and cooking, neither of which happen in a shopping trolley.
