Welcome to the forums Ranime I see this is your first post.
A quick search online shows me that Lebanon imports bovines (cows) and bovine meat heavily (9th and 10th place in order of dollar transaction):
Seeing as, if this website is correct, your major food import is cows/cow meat you could do a paper on foodborne illness from improperly manufactured meat or tainted meat (mad cow disease which I just learned online isn't from a microbe but a misfolded protein... possibly... but that would still be microbiology). You could research food illnesses in your country due to beef and find out what countries the beef came from.
Fresh cheese was next on the list, from what I saw, and so on. You can look at water activity in different foods as it relates to the presence of bacteria or it being the environment for bacteria to grow and proliferate.
Honestly you should choose something you know enough about to get started and know what direction to take. Otherwise throw a bunch of microbe names in the air and the one that goes the furthest could be your choice
