Special Issue Information

Dear Colleagues,

The ubiquitous presence of mycotoxins in food and feed presents an ongoing challenge to global health and agricultural economies. Addressing these challenges requires a comprehensive understanding of the diverse mycotoxin types, their occurrence, and innovative analytical strategies.

This Special Issue on the potential risks and analytical challenges of mycotoxins in food and feed aims to explore the critical aspects of mycotoxin contamination in food and feed, focusing on the associated risks and analytical hurdles. It will shed light on the latest advancements in mycotoxin detection, mitigation, and regulatory efforts, and bridge the gap between scientific insights and practical applications.

I invite you to submit your research. Submitted manuscripts may include original research articles, reviews, and concise communications investigating mycotoxin detection, impact, and countermeasures that can help foster collaboration and knowledge exchange, and generate transformative insights for safer food and feed systems.

Dr. Anindya Chanda

Almonds are an essential crop for the economy of California. However, mold and mycotoxin contamination of this commodity has a serious impact on food safety and international trade. The contamination levels of molds and the aflatoxigenic potential of Aspergillus section Flavi isolates were studied on almonds collected at a processing plant in California. The mean total fungal count for 80 samples was 1.0 × 104 CFU/g, while 62 samples (77.5%) had a total mold count less than 1.0 × 104 CFU/g. The most common fungal contaminants were Aspergillus section Nigri (100% of samples), followed by Penicillium (57.5%) and Cladosporium (52.5%) species. Rhizopus, Fusarium and Alternaria spp. were less frequent. A total of 26 A. section Flavi strains were identified, with most strains (23) belonging to the L morphotype of A. flavus. In addition, two S morphotypes of A. flavus, and one A. tamarii strain were observed. Other Aspergillus species, including A. terreus and A. ochraceus were rare. High Performance Liquid Chromatography (HPLC) analysis revealed that 9 out of 13 isolated A. flavus strains produced aflatoxin B1 (AFB1) on yeast extract sucrose media. The highest levels of AFB1 were produced by two A. flavus isolates belonging to the S morphotype (78 and 260 µg/kg). Increasing temperatures and drought conditions may change the population dynamics of toxigenic mold strains on almonds, emphasizing the need to continue monitoring these fungal populations.

Fungal and mycotoxin control at a primary stage in the food chain is crucial to maintaining the nutritional quality of animal feed. The control of fungal and mycotoxins is one of the essential points that a good biosecurity program must establish to ensure the safe feeding and protection of animal and human health. Acquiring a comprehensive understanding of the role of mycotoxins is vital to identifying breaches of this control and enabling the performance of proper risk assessments and accurate risk management strategies. This study focused on the identification of regulated and emerging mycotoxins in agricultural fields and dairy farms through an analytical methodology by ultra high-performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-QTrap-MS/MS). This allowed us to identify a Portuguese mycotoxin profile in the maize value chain for the first time. Regarding our occurrence data, mycotoxins were identified in all samples, namely seeds, flowering plants, grain and forage at harvest, maize silage, and animal feed. FBs and ENNB were highly present in all stages of the production cycle. This work offers an initial insight into a full screening of regulated and emerging mycotoxins within an important agricultural commodity. The high occurrence of these compounds points to the need to perform occurrence surveys from an integrative perspective to protect consumers’ health, especially within food chains that provide various important staple foods worldwide.
