Sampling Method for Testing TSNAs in Farmer Bales
TSNA Technical Report
The CORESTA Sub-Group TSNA in Air-Cured and Fire-Cured Tobacco was established to study the effect of any aspect of tobacco production that may affect the level of TSNA in cured leaf up to the point of sale and then suggest practices that growers could implement to reduce the accumulation at any stage prior to marketing their cured leaf.
A critical part of this procedure is sampling of cured leaf marketing packages either at, or soon after, the point of sale. The Sub-Group was tasked with developing a standardized protocol for this sampling. The results of tests to establish such a protocol are presented in this report.
