Pyrrolizidine alkaloid intoxication outbreaks in fattening pigs associated with drought-related feed contamination
This report documents a large-scale outbreak of PA intoxication in swine, associated with the use of barley contaminated with PA-producing plants, most likely Heliotropium europaeum, in central Spain. Environmental factors, such as drought followed by humid conditions and reduced herbicide application, likely facilitated PA-containing weed growth and subsequent contamination of cereal crops. This case underscores the growing risk of toxicoses linked to climatic and agronomic factors, emphasizing the need for enhanced monitoring and control of feed sources.
