Good Morning World. :-) 
I would like to hear your opinion on the tasks of QA in the production plant. My bosses want me to do some stuff which i think are not related to the QA field, and since I am new to the field there is not a lot of previous experience. They want me to make new and old spec sheets for the products that we are making in Adobe Illustrator. Verify and order labels. Contact companies for repair and all other sort of stuff that are not really in my responsibility imho. Can somebody share what are the tasks of a requalr QA in a food production industry?
Thanks for your help guys. 
Good morning ~ !
Like many have said above - these DO and can fall under QA's responsibility depending on the structure, culture, audit scope, size, etc. of your company.
Label making, label verification, spec sheets, are all daily document stuff I gotta do for my job to be done well. Scheduling and calling maintanance repairs / services are a part of this too.
and because you specifically mentioned you are new, I would fall under the thought process that these tasks are good foundations anyways later on, -let's say if you have a tech or another colleague on your QA team, you can then appropriately know they are doing the job right and delegate accordingly now that you know the essentials.
In terms of auditing processes, I do something similar to what TimG wrote, so that the senior mgmt team is aware and reminded that QA shouldn't be in charge of everything so that we aren't auditing things we've done.
