Alternaria toxins, secondary metabolites produced by fungi of the Alternaria genus, represent a growing threat to global food safety. Their importance has been formalized at the European level with Commission Recommendation (EU) 2022/553, which establishes indicative levels for Alternariol (AOH), Alternariol Monomethyl Ether (AME), and Tenuazonic Acid (TeA). Exceeding these levels should lead to in-depth investigations to identify the factors causing Alternaria toxin contamination.
Alternaria toxins are present in a wide variety of crops, particularly cereals, tomatoes, fruit, and oilseeds, and are the subject of increasing attention from regulatory authorities such as EFSA, due to their potential harmful effects on human health.
For laboratories, demonstrating the accuracy and reliability in the analysis of these contaminants in complex matrices is not only a regulatory requirement but an ethical imperative to protect consumers, especially for sensitive products such as cereal-based foods intended for infants and young children.
To support your continued compliance and analytical excellence, our Progetto Trieste Proficiency Test scheme has reinforced its 2026 program with two crucial and highly specific PTs:

PT for the research of Alterotoxins in wheat

PT per la ricerca di alterotossine in salsa di pomodoro
(VF5708A) – Round Giugno 2026
- Shipping date: June 15 2026
- Deadline for online orders: May 1st 2026
- Test Material: tomato sauce, 100g x 1 sample, spiked
- Molecules under study: Alternariol (AOH), Alternariol monomethyl ether (AME), Tenuazonic acid (TeA), Tentoxin (TEN). All the molecules will be present.
- Indicative concentrations: < 60ppb
- Price: 410,00€
Our commitment to supporting laboratories in tackling these new parameters goes beyond merely offering Proficiency Tests. We aim to gather valuable information to quickly develop the PT schemes most needed by the market.
Share Your Expertise Through Our Survey
We invite you to participate in our short survey focusing on Alternaria toxins. Your feedback is essential and will directly shape our future programs:
- What are the major difficulties you are encountering when validating these analytical methods?
- Which matrices (e.g., cereals, tomato products, oilseeds, tree nuts) are currently the most relevant and urgent for your Proficiency Testing needs?
To thank you for your valuable time and input: Receive a 30% discount on all our 2026 Alternaria Toxin PTs simply by completing the survey!
Furthermore, the aggregated results of the survey will be shared with all participants, providing a useful overview of current market challenges and priorities.
Do you want a PT tailored to your supply chain? Fill out the survey with your preferences for Altertoxins!
We are constantly committed to monitoring risk trends and the needs of international laboratories. The monitoring of Alternaria toxins, as also highlighted by EU recommendations, extends across a wide range of products.
For this reason, we want to directly engage our network of professionals and invite you to express your interest in new matrices contaminated by Alternaria toxins (e.g., oilseeds, spices, etc.). Your feedback is crucial for developing new PTs that reflect the most current analytical challenges in the agri-food sector.
OUR POINTS of STRENGHT
- For all the PTs belongs to the Progetto Trieste – Mycotoxins line, it is possible to submit 2 sets of results and evaluate them in the Final Report, thus, with one subscription, 2 laboratory technicians, or 2 different methodologies.
- The sample is ready for analysis, no reconstitution is needed.
- If you order several PTs belonging to the same round, you will only pay shipping costs once!
Find out about all the PTs planned for June by consulting our programme! - Test Veritas has more than 25 years of experience as PT provider.
