Meat product rounding rules for nutrition label

Should I follow the FDA's rounding rules when creating a nutrition label for a meat product or does the USDA have its own rounding rules?

If it's a meat product or something with a substantial percentage of meat the labeling will need to go through USDA label approval processes, and be FSIS inspected.  

From an old directive

1. If a plant determines through testing that the amount of retained moisture in a particular item is a fractional percentage (e.g., 0.3, 0.4, 0.5, or 1.3 percent, etc.), how would the agency expect this to be labeled?

Answer: As with nutritional labeling, rounding rules would apply (i.e., round to the nearest whole number). Therefore, labeling of fractional percentages of retained water would not be required. For example, 0.5 percent-retained water is rounded up to 1 percent and 1.3 percent is rounded down to 1 percent.
