Determination of the country of origin of farm-raised shrimp (family penaeide) using trace metal profiling and multivariate statistics.
The role of Customs and Border Protection on shrimp importations into the United States is discussed. The focus of this work is to present evidence that the comparison of trace metal data from an imported shrimp sample to an authentic reference database using multivariate statistics produces an accurate geographic location of the sample. The authentic reference database includes data from more than 100 sampling sites spread over eight countries along with the accuracy of each site relative to its known geographic origin. Potential sources of bioaccumulation are briefly discussed; however, it is beyond the scope of this work to provide scientific verification of the mechanism for trace metal uptake. Three examples of imported shrimp are provided for demonstrating the exact procedure for determining their true countries of origin.
