Understanding Food Spoilage: Mechanisms, Shelf-Life Determination, and Safety Standards
Abstract: Food spoilage poses significant challenges to the global food industry, impacting both food safety and economic sustainability. The main causes of food quality deterioration are microbial and non-microbial spoiling. Microbial spoilage primarily results from the activity of bacteria, yeasts, and molds, which thrive under favorable environmental conditions. These microorganisms can lead to food poisoning and spoilage through the production of off-flavors, discoloration, slime formation, and the accumulation of harmful toxins. …

Driving Determinants Influencing Mortality of Goats in the Tropics: Challenges for Sustainable Livestock Development
Abstract: Goat mortality in the tropics is driven by multifactorial determinants that pose critical challenges to sustainable livestock development. Key contributors include infectious diseases, such as peste des petits ruminants, goat pox, enterotoxemia, and haemonchosis, which remain prevalent due to limited vaccination coverage and inadequate biosecurity measures. Bacterial infections, like pneumonia and caseous lymphadenitis, along with parasitic infestations, such as coccidiosis and liver fluke, significantly reduce goat survival rates, especially in …
