John,
I generally have great confidence in the accuracy of your statements.
But, where do you find the statement that “the Feds only require 2.84 oz in a 5
oz can (56.8%)” of tuna?
Filling accuracy of canned tuna is regulated by the NCWM, a conference of
state, regional, and local regulators,
I took it directly from the article, but I was not able to "fact check" it (I
hope the reporter did), as I couldn't find the Federal rule; I did try.
Remember that USDA, not FDA, regulates meat. I was surprised that NOAA
regulates fish, but I did find a source to confirm that. Given that
NOAA has promulgated (mirrored) a WHO Food and Agriculture Organization
standard here. It's an international standard and not one that NOAA
devised. That explains the double-ell before "-ing" and "-ed" and the
use of "-our" instead of "-or".
I suspect that NOAA's involvement might stem from
John,
All that I can find on the *inspection* of canned tuna is from NIST (NCWM)
Handbook 133 (2016 Edition),
Paragraph 2.5 on Page 32: (wording adapted to canned tuna)
All cans in the sample will be opened and measured.
The mass of each can plus the mass of each drained-away liquid is
The following are helpful but none directly answer the question. Tuna producers
petitioned for "drained weight" years ago, but "nada"
happened:http://www.fda.gov/ohrms/dockets/dailys/00/Sep00/090100/c56.pdf
NOAA is involved and this touches on drained weight, but as a basis for meeting
Another question. Since all cans of tuna in the sample are opened and
measured, (and no inspector is expected to eat the drained tuna.)
Why does the NCWM test procedure not prescribe a direct measurement of the mass
of the drained tuna? (ultimately to be discarded)
If measured carefully, that
