description: Poultry spoilage presents a significant challenge in the food industry due to its susceptibility to microbial contamination and enzymatic degradation, leading to decreased product quality, safety concerns, and economic losses. Deciphering the mechanisms underlying poultry spoilage is essential for implementing effective control strategies and ensuring the safety and integrity of poultry products throughout the supply chain. This abstract provides a comprehensive overview of the factors contributing to poultry spoilage, including microbial pathogens, enzymatic activities, and environmental conditions. Microbial contamination, predominantly caused by bacteria, molds, and yeasts, is a primary driver of poultry spoilage. Common spoilage bacteria such as Pseudomonas, Enterobacteriaceae, and lactic acid bacteria proliferate rapidly under favorable conditions, producing off-flavors, odors, and toxins detrimental to poultry quality and safety. Additionally, molds and yeasts contribute to spoilage by producing visible signs of decay, including discoloration, slime formation, and off-odors, rendering poultry products unpalatable and unsuitable for consumption. Enzymatic activities play a pivotal role in poultry spoilage, with endogenous enzymes catalyzing biochemical reactions leading to texture degradation, lipid oxidation, and protein denaturation. Enzymes such as lipases, proteases, and oxidases accelerate the deterioration of poultry products, compromising their sensory attributes and nutritional value. Furthermore, environmental factors such as temperature, humidity, and packaging conditions significantly influence the rate and extent of poultry spoilage, exacerbating microbial growth and enzymatic reactions. Understanding the complex interplay between microbial, enzymatic, and environmental factors is paramount for devising targeted interventions to mitigate poultry spoilage. Novel preservation technologies, including high-pressure processing, modified atmosphere packaging, and antimicrobial interventions, offer promising solutions for extending the shelf life and enhancing the safety of poultry products. Moreover, advancements in molecular microbiology and omics technologies enable the rapid detection and characterization of spoilage microorganisms, facilitating proactive quality assurance measures in poultry processing facilities. In conclusion, deciphering poultry spoilage mechanisms is instrumental in safeguarding consumer health and promoting industry sustainability. By elucidating the intricate pathways of spoilage development and implementing proactive control measures, stakeholders can minimize product losses, enhance food safety standards, and meet consumer demands for high-quality poultry products.
