Climate Change-A Global Threat Resulting in Increasing Mycotoxin Occurrence

Area of Science:

• Agricultural Science
• Mycology
• Climate Science

Background:

• Global warming is increasingly linked to mycotoxin-producing moulds worldwide.
• Climate change impacts host-pathogen interactions and mould development, affecting mycotoxin production.
• Emerging concerns include increased Aspergillus flavus growth in Europe, raising aflatoxin risks, and shifts in Fusarium species profiles.

Purpose of the Study:

• To address the growing threat of mycotoxin contamination in food and feed due to climate change.
• To highlight the need for novel diagnostic tools and better understanding of agricultural cultivars and toxicogenic moulds.
• To propose a preventative strategy against toxicogenic mould and mycotoxin contamination.

Main Methods:

• Review of scientific literature on climate change, mycotoxins, and fungal growth.
• Analysis of geographical trends in mycotoxigenic mould prevalence, specifically Aspergillus flavus and Fusarium species.
• Development of a preventative strategy framework.

Main Results:

• Projected increase in cereal contamination by aflatoxins due to favourable European climate for Aspergillus flavus.
• Observed significant shifts in the prevalence of mycotoxigenic Fusarium species, with Fusarium graminearum becoming a major concern in Northern and Central Europe.
• Identification of the need for proactive measures against mycotoxin-producing moulds.

Conclusions:

• Climate change necessitates urgent attention to mycotoxin contamination risks in agriculture.
• Preventative strategies are crucial to mitigate the impact of toxicogenic moulds and mycotoxins on food and feed safety.
• Further research into biological features and diagnostic tools is essential for effective management.
