Research – Latest EU audit questions Turkish approach to control mycotoxins

ACSA

An audit carried out between the months of May and June 2022 by the General Directorate of Health and Food Safety (DG SANTE) of the European Commission on the official controls that Turkey applies in relation to mycotoxins in dried figs and pistachios concludes that they are not effective. This conclusion fully coincides with the alerts and rejections at the border level that are notified through the Rapid Alert Network for Feed and Food (RASFF), where figs and pistachios from Turkey are prominent players due to the presence of aflatoxins.

It should be noted that the EU establishes that each shipment of dried figs and pistachios coming from Turkey or through Turkey must have a health certificate issued by the authorities, as well as the results of official sampling that demonstrate compliance with the requirements on maximum levels. of aflatoxins. It should be remembered that no level has been established for Ochratoxin A in dried figs. Figs from Turkey are subject to a 20% analysis frequency by EU countries, while it is 50% for pistachios.

There is a decreasing trend of rejection decisions based on Turkish pre-export tests. This fact contrasts with the results obtained in the controls carried out by the EU countries. In short, the ability of the Turkish control system to ensure that all shipments of exported dried figs and pistachios have been produced in accordance with EU regulations is called into question.

The auditors found that official controls are not designed to verify and control whether farmers implement mycotoxin control measures. Reports on official controls, including the effectiveness of HACCP schemes and controls carried out by processors, are also poor.

EU – Entry into force of the new maximum limits for Ochratoxin A

ACSA

In January 2023, the new maximum limits of ochratoxin A in certain foods approved in August by Commission Regulation (UE) 2022/1370 of August 5, 2022 will come into force, amending Regulation (EC) nº 1881 /2006 regarding the maximum content of ochratoxin A in certain food products .

Ochratoxin A is a mycotoxin produced naturally by fungi of the genera  Aspergillus  and  Penicillium  and is found as a contaminant in a wide variety of foods, such as cereals and cereal-based products, coffee beans, dried fruits, wine and grape juice, spices and licorice. Ochratoxin A is formed during drying in the sun and storage of crops. Formation can be avoided by applying good drying and storage practices.

Regulation (EC) nº1881/2006 already established the maximum content of ochratoxin A for certain foods. This new regulation:

Establish maximum limit of ochratoxin A for:

  • Nuts other than raisins.
  • Certain licorice products.
  • dry herbs
  • Certain ingredients for infusions.
  • Certain oleaginous seeds.
  • pistachios
  • Cocoa powder
  • Malt-based non-alcoholic drinks

Reduces the existing maximum limits of ochratoxin A for:

  • Bakery products.
  • raisins
  • roasted coffee
  • instant coffee

In addition, it extends to all species the provisions in force relating to ochratoxin A in certain species.

Breaking Latest News

A study found two mycotoxins in some packages of grated Grana Padano. Specifically, the paper found ochratoxin and sterigmatocystin, both produced by microscopic molds. The former was found in 48.6% of the cases analysed, while the latter was present in 94.4% of the packs of grated “grana” type cheeses sold in supermarkets. These would be small but significant quantities.

Research – Evaluation of the dietary exposure of the Catalan population to mycotoxins of the genus Fusarium

ACSA

Within the framework of total diet studies, the Catalan Food Safety Agency (ACSA) publishes a second study on the evaluation of mycotoxins: “Evaluation of the dietary exposure of the Catalan population to mycotoxins of the genus Fusarium”.

In 2014, a first study was published in which the presence of the main mycotoxins in food intended for human consumption in the Catalan market was determined, and the intake of food linked to this contamination to estimate the food exposure of the population residing in Catalonia, and evaluate the risk to health (ACSA, 2014). Considering the results obtained, the ACSA considered it necessary to carry out this second, more specific study on mycotoxins, evaluating those that were found most frequently in the foods of the Catalan market, the mycotoxins of the genus Fusarium, and also taking into account the most exposed population groups.

The present study shows that the mycotoxins detected with greater frequency were DON and ENNB followed, with a much lower frequency, by mycotoxin T-2 and mycotoxins FB1 and DON-3G. The rest of mycotoxins analyzed (3-ADON, 15-ADON, NIV, FUS-X, zearalenone, HT-2, FB2 and FB3) will always present levels below the detection limit.

All the age groups evaluated have an exposure to DON and ENNB lower than the respective safety values. The average exposure of the adult population and children in Catalonia to the mycotoxin DON presents values ​​between 7.5% and 10.1% of the safety value. The average exposure of the population to ENNB presents values ​​​​that are two orders of magnitude lower than the extrapolated safety values.

Total diet studies make it possible to better understand the reality linked to the main chemical pollutants that reach the Catalan market, and in this way specific decisions can be made to correct possible risk situations for the health of consumers.

Research – Occurrence of Aflatoxins and Ochratoxin a during Merkén Pepper Powder Production in Chile

MDPI

Abstract

Berry fruits of Capsicum annuum L. cv. “Cacho de Cabra” are used for the manufacture of a traditional pepper powder known as Merkén. In the present study, aflatoxins (AFs) and ochratoxin A (OTA) contamination in berry fruits of C. annuum was determined at harvest, drying, and smoking stages of Merkén production, in cumin and coriander seeds used as Merkén ingredients, and in the final packaged Merkén produced by local farmers. Additionally, Merkén samples from local markets in the region of La Araucanía (Chile) were also evaluated. Chromatographic analysis was based on a qualitative method. AFs and OTA were not detected on pepper pods and seeds. There was no detection of AFs and OTA on cultured Aspergillus and Penicillium strains isolated from pepper pods, cumin and coriander seeds and Merkén. The lack of AFs/OTA-producers among the isolated fungal species can explain and support the absence of contamination in pepper pods. In contrast, the AFB1 was detected in 75% of Merkén obtained from farmers and 46% of Merkén samples purchased from local markets; while OTA was detected in 100% of Merkén samples obtained from farmers and local markets. In the Merkén production chain, the harvest and post-harvest are key stages for fungal growth while the commercialization stage is highly susceptible to AFs and OTA contamination.
