I suspect the ADA document is somewhat "antique" (or simply un-maintained) despite it's ending inclusion of 2014, eg I noticed this comment -
The upcoming 2005 FDA Food Code............
Many of the links, especially FDA ones, seem broken. Not altogether unusual of course.
Amazingly the scope of application of "food service" seems to be defined nowhere in all these US "food-service" documents. A google definition of food service is -
The definition of food service is the industry related to making, transporting or selling prepared foods to restaurants, hospitals, schools and lodging establishments.
But above is I think probably incomplete. This, slightly OT, interpretation looked a more plausible one to me -
Food Service Guidelines for Federal Facilities
Two types of food service are provided in federal facilities. One type includes food service
venues in which food is sold (such as cafeterias, cafés, and vending machines) and customers
purchase their food and beverages from a variety of choices. The other type includes venues in
which food is served (such as federal hospitals, correction facilities, or military dining facilities),
and the government is responsible for providing individuals with meals that meet all or part of
their daily or weekly nutrition needs and individual choice may be limited.‡3 With the exception
of the food safety standards, which apply in both types of venues, the standards in the Food
Service Guidelines for Federal Facilities are written specifically for federal food service venues
where food is sold (although they can be adapted to venues where food is served).
I also noticed the ADA document's footnotes (No.2 is rather cryptic) -
1. References in this Guide to the "FDA Food Code" are to the FDA 2001 Food Code, available online at http://www.cfsan.fda.../fc01-toc.html . The Food Code is a model code developed by the FDA which is offered for adoption by local, state, and federal governmental jurisdictions for administration by the various departments, agencies, and other units within each jurisdication that have been delegated compliance responsibilities for food service, retail food stores, or food vending operations. Once adopted, the Food Code provisions become the regulatory requirements for that jurisdiction. In jursidictions where the Food Code has not been adopted, its provisions are not requirements for food establishments. In the text of the Guide, we presume that the Food Code has been adopted and, hence, refer to the Food Code as imposing requirements. This Guide applies general principles of the ADA to the Food Code.
2. Food service establishments are also "public accommodations" that are covered by Title III of the ADA, regardless of the number of employees. As public accommodations, food service businesses may need to make physical changes or other modifications to their facilities to serve members of the public with disabilities. The Department of Justice (DOJ) enforces Title III of the ADA and provides free information about it. You can contact DOJ at (800) 514-0301, or log onto www.ada.gov for more information.
Overall, I get the impression that the (Post 2) linked ADA document's scope is not targeted to routine manufacturing/distribution facilities as per the OP's query. Unless perhaps the OP is classified as a "food service distributor" within the context of SQF module 12 / this wiki -
Then again there is perhaps another ADA document which is non-food service targetted.
Or another footnote.
