Criticism of label readability is not uncommon; for example, Canadian researchers found that medicine labels did not consistently follow legibility guidelines.<ref>{{cite web|title=Small font, all capitals makes prescription labels too hard to read|url=http://www.torontosun.com/2014/07/09/small-font-all-capitals-makes-prescription-labels-too-hard-to-read-study|access-date=14 July 2014}}</ref> In some countries and industries, for example the UK (food)<ref>{{cite web|title=Food Standards Agency - Clear food labelling - Guidance|url=http://multimedia.food.gov.uk/multimedia/pdfs/clearfoodlabelling.pdf|access-date=14 July 2014|archive-url=https://web.archive.org/web/20140715013822/http://multimedia.food.gov.uk/multimedia/pdfs/clearfoodlabelling.pdf|archive-date=15 July 2014|url-status=dead}}</ref> and EU (medicines)<ref>{{cite web|title=Eurpopean Commission: Guideline of the readability of the labelling and package leaflet of medicinal products for human use|url=http://ec.europa.eu/health/files/eudralex/vol-2/c/2009_01_12_readability_guideline_final_en.pdf|access-date=14 July 2014}}</ref> label guidelines are not legally binding (the latter using phrases such as ''"The type size should be as large as possible to aid readers..."'') and thus are unenforceable. On the other hand, countries may stipulate legal minima for readability, such as the USA's FDA on nutritional information<ref>{{cite web|title=FDA - Labeling and Nutrition|website=[[Food and Drug Administration]]|url=https://www.fda.gov/food/guidanceregulation/guidancedocumentsregulatoryinformation/labelingnutrition/ucm064904.htm|archive-url=https://web.archive.org/web/20130326055655/http://www.fda.gov/Food/GuidanceRegulation/GuidanceDocumentsRegulatoryInformation/LabelingNutrition/ucm064904.htm|url-status=dead|archive-date=March 26, 2013|access-date=14 July 2014}}</ref> and Australia/New Zealand's code for food labels and packs.<ref>{{cite web|title=Food Standards Australia New Zealand|url=http://www.foodstandards.gov.au/code/userguide/Documents/Guide%20to%201.2.9%20-%20Legibility%20Requirements.pdf|access-date=14 July 2014|archive-date=12 February 2014|archive-url=https://web.archive.org/web/20140212005647/http://www.foodstandards.gov.au/code/userguide/Documents/Guide%20to%201.2.9%20-%20Legibility%20Requirements.pdf|url-status=dead}}</ref>
