TestQual 127 Mycotoxins (Aflatoxins and OTA)

 

About the analytes 

Mycotoxins are secondary metabolites with low molecular weight produced by different species of fungi1  that can grow at any time, including pre-harvest until post- harvest 2. The development of this fungi depends on various factors, but to include some of the more relevants are the temperature and humidity of drying and storage of the spices.

The annual report of RASFF from 2017 set the mycotoxins in the second spot from a top 10 ranking of hazardous food contamination that year 3, mycotoxins and more specifically aflatoxins (AF) B/G and the Ochratoxin A(OTA) produces in humans metabolites with mutagenic, teratogenic and carcinogenic effects 2. The International Agency for Research on Cancer (IARC) classifies the AF as cancinogenic substances from group 1 (They cause cancer to humans), while the OTA has been classified as a cancinogenic compound from the group 2B (There hare some evidences that causes cancer to humans) 3.

You can check the current legislation in the EU for OTA in paprika here and aflatoxins in different matrixes, including paprika here.
