I have been working with government guidelines and regulations of labeling on animal health labels for 30 years for the regulatory departments of Bayer, Merck, and Ceva pharmaceutical corporations.
I have done a few food labels and they are similar. USFDA guidelines need to be followed with placement of information and minimum sizes of type. I have a copy of their guidelines. I developed the style of labels as well as place the content on the right panels with barcodes. Many of the labels and packaging was translated in to several languages, French, Spanish, Japanese etc.
I have a page in my portfolio regarding labeling if you wan to take a look at the labeling I have done.
I would be delighted to work with your company and would appreciate it if you can send me a sample of your text and a label size so I can head off any potential problems.
Best regards.
