Biotic contamination of food and environments Mod. 2 Postharvest diseases
Code: G3002B
Teacher:  Matias Pasquali
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 2,5
Practices in classroom: 0,5
Basic aims:  Fundamental knowledge about postharvest diseases and disorders caused by biotic agents, such as fungi and bacteria, and about their diagnosis. Moreover, students will learn how to acquire information necessary to understand EU rules on biotic and abiotic residues in food as well as on analytical methods for their identification. Specific food-chain specificities will be detailed. The final aim will be to become able to manage product protection as well as safety during storage.
Acquired skills:  At end of the course, the student should be able to recognize the main symptoms caused by biotic agents in postharvest and to be aware of the most frequent alterations occurring during storage as well as of the main risks, legislation and most effective analytical methods related to residues in stored food products.
Course contents:  Postharvest alterations and loss extent. Outlines of plant pathology. Pathogens in post harvest diseases. Main genera of fungi and bacteria that causes post harvest losses. Mycotoxins and mycotoxicoses. Control of postharvest diseases.
Program:  Postharvest alterations and loss extent (physiological alterations, damages due to physical, chemical and biological conditions or parasites; losses from harvest to market). Outlines of plant pathology (the concept of disease in plants, classification of plant diseases, the cycle of disease, host-pathogen relationships). Pathogens in post harvest diseases (phytopathogenic fungi and bacteria, their pathogenesis) Main genera of fungi and bacteria that causes post harvest losses. Mycotoxins and mycotoxicoses Control of postharvest diseases (physical, chemical and biological methods; integrated control; residues and legal restrictions)
Prerequisites:  The course will be better understood if students know the main topics of general biology
Preparatory instructions:  Info not available
Learning materials:  De Cicco, Bertolini, Salerno. Patologia post raccolta dei prodotti vegetali. Piccin
Slides
Other info:  Final test will be a written test followed by an oral examination.
An individual research on a disease in post harvest (detailing the pathogen and the host) is a further option for increasing the final score of the exam. Details on how to perform the individual research are reported in the material provided for the course.
The individual research has to be sent at least 48hrs before the exam to matias.pasquali@unimi.it
