Dear hlehman,
Thks yr reply.
GMO related issues not really my area of expertise but I can offer a few comments –
(1) Re – FSIS approval, I guess this relates to –

I note from yr website that NGP standard sets appropriate product threshold levels for GMO content.. Are these FSIS originated standards or ? ( I could not find any data ascribed to USDA on the IT). I noticed that historically the numbers used have (not surprisingly) caused considerable debate, eg this 2007 article –

I also noticed this later comment in a (2014) USDA conference paper –

It frankly seems to me that some caveats exist regarding the scope of the FSIS approval for the NGP standard (at least in FSIS's opinion
).
(2) As I understand NGP standard typically uses a threshold level of 0.9% GMO material stated to be in alignment with EU regulations.
This assumption may not be fully correct. For example –
http://www.food.gov....gm/gm_labelling
and (for certain situations) -
In order to address the LLP issue, a partial solution has been adopted by some countries. For example,
EU regulation No 619/2011, in force since July 2011, lays down the methods of sampling and analysis for
the official control related to GMOs in feed. This regulation sets a threshold level of 0.1 percent for feed,
a so-called “technical solution”. However, for food and seed this threshold is 0 percent.
(FAO, 2014)
(3) I noticed that the confidence level mandated for the sampling procedure in NGP standard is 90%. IMEX this is rather unusual, ie 95% is more common, although the exact choice is, AFAIK, arbitrary.
It is obvious that an enormous amount of work has been put into developing the NGP standard / website and the content transparency is rather impressive IMO for such an emotive topic.
For information only, I noticed this (2010) critical survey of GMO issues within USA. Accuracy unknown.

Regarding yr accreditation query, maybe UKAS ? (if you can't beat them, ........)
