Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza
Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Identification, Aggressiveness And Mycotoxin Production Of Fusarium Graminearum And F. Boothii Isolates Causing Fusarium Head Blight Of Wheat In Nebraska, Esteban Valverde-Bogantes
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Fusarium head blight (FHB) is an economically important disease caused by several Fusarium species affecting wheat. Besides causing significant yield losses, infected grain may be contaminated with mycotoxins, primarily trichothecenes, that are harmful to both humans and animals. In recent years, reports of shifts in FHB pathogen populations in North America have highlighted the need for increased vigilance. This dissertation describes a four-year survey evaluating the species, trichothecene genotype and phenotypic diversity of FHB pathogens infecting Nebraska wheat. Most of the isolates were identified as F. graminearum (n=67). Additional species included F. boothii (n=3), F. poae (n=2) and F. acuminatum …
