Ah, sorry I hadn't noticed that. I know that Campden BRI publish guidance etc, but it costs - £90 for non-members.
There's also this FSA one:
http://www.food.gov.uk/sites/default/fi ... cguide.pdfI don't think that it offers much more help though. Commercially, the onus is on the producer to show that it's safe, not the other way around.
I know that members have kept air dried stuff in the piece for absolutely ages - well over a year. Your Bresaola would also keep perfectly well in the piece (probably even without refrigeration), but that doesn't help when your butcher is being kind enough to slice it. I'd have thought that a well made vac-packed sliced Bresaola should be OK for quite a while though if refrigerated. What does your butcher think?
I'm loathe to suggest it, but I have frozen sliced Bresaola in vac-packs - it's more successful than you may think.
Sorry not to be more help.
