AOAC Methods Review (Codex STAN 234)

10. Is the method fit for purpose to measure the provision as listed in the commodity standard? 11. Is the method fit for purpose according to technical evaluation? 11a. Please provide information on technical evaluation

Yes

No

According to CXS 193-1995, the codex maximum level for lead in secondary milk products is 0.02 mg/kg. I feel anxious about we might not get enough sensitivity when a frame atomic absorption spectrometer is used. So, I recommend to get an additional data of LOQ.

12.Is the method listed alongside any other methods in CXS 234?

No

13. Is further review of this method needed?

No

13b. 1. If no, please provide final recommendation for CXS 234, considering only the method under review 13b. 2. If no, please provide final recommendation for CXS 234, considering all methods listed for this commodity and provision

Additional review needed
