How the derived figures were obtained

salt %      = sodium mg / 1000 x 2.5420 / 100 x 100
            = 1,756 / 1000 x 2.5420 = 4.464 g per 100 g
brine %     = 100 x salt / (salt + water)     [FSIS-GD-2016-0002]
            = 100 x 4.464 / (4.464 + 41.2) = 9.777 %
MPR         = water % / protein % = 41.2 / 21.1 = 1.955 : 1

What these figures do and do not say

The brine concentration above is computed from this food's own sodium and water using the FSIS formula, 100 x salt / (salt + water). It is a description of a finished commercial product, not a target. FSIS cites 10 percent brine after equalisation as the figure that prevents Staphylococcus aureus enterotoxin production during warm drying, and 9 CFR 319.106(b)(4) requires not less than 10 percent for a dry cured ham made without nitrate or nitrite.

Water activity cannot be computed from composition. It is a measurement, and it is the measurement that decides shelf stability. The published limits are 0.85 in air and 0.91 vacuum packed, both from FSIS-GD-2014-0010.
