How the derived figures were obtained
salt % = sodium mg / 1000 x 2.5420 / 100 x 100
= 737 / 1000 x 2.5420 = 1.873 g per 100 g
brine % = 100 x salt / (salt + water) [FSIS-GD-2016-0002]
= 100 x 1.873 / (1.873 + 69.6) = 2.621 %
MPR = water % / protein % = 69.6 / 24.5 = 2.841 : 1Full composition, per 100 g

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.
