Dear BruceMartin,
I think I understood you to imply that separate buildings are involved. This would surely involve different clothing etc ?. If within same overall production location, are Physical separations involved? Is yr vegetable operation really classified as low risk ? I’m rather surprised unless it is going to be further heat treated (somewhere).
I think for “low risk” it may depend on the precise operation and, assuming other things such as BRC are equal, the company philosophy / products / activities / onward requirements.
IMEX of factories doing raw frozen seafood, non-RTE, to be further processed, eg at a minimum cooked (somewhere}, first stage activities involving relatively messy operations, eg gutting fish, squid are typically individually separated by product and minimally the crews’ overgarments. . Subsequent relatively clean stages, eg size selection, are often not physically product separated and free movement is possible. 3rd stages post-freezing, eg packing / storage are often physically location-only separated although free employee movement to 2nd stage areas may be possible. Some companies totally isolate the last stage as per their own / customer requirements creating a sort of showpiece.
Obviously factors such as allergens may create specific requirements also.
