Food in hand luggage

I'm flying with Ryanair soon, and would like to take a small amount of food with me in my hand luggage. In general, what are the rules/restrictions on this? I know that there might be some safety issues concerning on-board security, the risk of carrying diseases, etc.

Some types of food that I'm thinking of:

Home made snacks (cakes, etc);
Bread / sandwiches;
Food in sealed container;
Food in a container that has already been opened.

Is there a list of guidelines that I should be aware of, to ensure that I'll be able to take everything with me on-board?

Best Answer

The website of RyanAir states that food is okay to bring.

I would suggest using a plastic bag or plastic container, instead of a metal container shaped as a bomb, but I guess that's pretty obvious. And there won't be any safety risks if you bring regular food like bread/sandwiches/etc.

You can't bring drinks through the security check, however you can buy drinks afterwards to take on your flight.
