- Abstract:
- ... The species identity on anchovy products was tested through COI mitochondrial DNA sequences analysis in 50 samples belonging to 20 different commercial lots, such as anchovy fillets in vegetal oil, canned anchovies and anchovy paste. Seven samples (14%) were found to be not from Engraulis encrasicolus meats, confirming concerns of species substitution. Conventional COI-DNA barcoding revealed the p ...

- Abstract:
- ... The purpose of this study is to establish a reliable detection method specific for event 98140, a type of multiple herbicide-resistant corn. Based on the 3′- flanking sequence of event 98140, qualitative and quantitative PCR detection assays were developed. The results revealed the LOD of 0.05% of GM maize for qualitative PCR assay and 4 transgenic haploid genome copies for quantitative PCR assay ...

In Finland, two main organizational models for meat inspection are used: official auxiliaries are employed 1) by the authority or 2) by the slaughterhouse (possible only in poultry slaughterhouses). Here, we examined the functionality of these two dif ...
