Predictive Analytics and Machine Learning for the Risk-Based Management of Agricultural Supply Chains
… food supply chains. Two central such risks are adulteration, in which unsafe food is sold for human consumption, and zoonotic diseases (i.e., viruses and diseases that can transfer from animals to humans through food supply chains) such as avian influenza, SARS, and COVID-19. This thesis focuses …

Complementary and alternate medicines: a forensic analysis of the potential adulteration of over-the-counter anorectics and "lifestyle" medicines in South Africa
Background: Complementary and Alternate Medicines (CAMs) in South Africa are not yet subjected to the same rigorous testing required for allopathic (prescription) medication, yet they are freely available as over-the-counter medicines. Past research has shown the presence of a banned drug, …
