This study ($25 download fee) compiled 254 incidents of food adulteration reported across from 20 countries in the Middle East and North Africa (MENA) region between 2019 and 2024, gathered from primary sources published in Arabic (85 %), English (10 %), and French (5 %). It also analysed 1261 notifications from the RASFF concerning food products originating from MENA countries during the same period.

The authors report that Lebanon and Turkey contributed the highest number of reported incidents with mislabelling (particularly expiry-date falsification) being the most common fraud.

The web-based surveillance identified 254 incidents, with Lebanon contributing to the highest number (15 %) followed by Egypt, Jorda and Iraq, while 78.9 % of all signals were classified generically as “food product’ and the most common issues involved expiration-date manipulation (62.9 %).

In the RASFF system, 1261 notifications linked to MENA-origin products were recorded, dominated by Turkey with 564 notifications (44.7 %) followed by Egypt (18 %) with alerts increasing between 2019 and 2024 and mainly triggered by contaminants (45.7 %) or unauthorized substances (16.9 %)

This paper (open access) reviews the history and exportation of turmeric in Africa and the safety issues of some toxic adulterants.

Priority adulterants were determined from global food safety alerts. A systematic bibliographic search was performed to identify appropriate methods and techniques for authentication and safety testing. The quality of each study was assessed according to PRISMA guidelines/protocol.

The authors report that African turmeric exportation is on the rise due to recent insights into the suitability of local cultivars, soil and climate for growing high-quality turmeric. There are limited data on turmeric adulteration for domestic consumption and export markets..

Global alert databases revealed lead chromate as the top hazard identified of all adulterants. Current techniques to detect adulterants are laboratory-based, and while efficient, there is a need for more rapid, field-friendly, non-destructive analytical tools.  The authors consider that – if lead chromate is considered to be the main tisk - then pXRF would be ideally suited as a field-based test in Africa. In the hope that it could be further developed and calibrated to detect below the regulatory level of 1.5 mg/kg lead in turmeric powder. There would be a need to cross-check pXRF screening results against a validated and accredited ICP-MS method as a reliable confirmatory tool.
