A omprehensive analysis of live-weight losses and meat quality indicators under logistic stress: The experience of Canada and the EU (2025-2026).

Abstract

This article presents the results of a comprehensive study on the impact of logistic stress on the quantitative and qualitative indicators of raw meat materials within modern agri-food systems in Canada and the European Union (EU). It was established that during the period 2025 - 2026, the livestock transport stage represents the most critical link in the supply chain, directly determining technological suitability and economic efficiency in meat processing. Based on the analysis of live weight loss dynamics ("shrinkage"), it was demonstrated that quantitative mass loss can reach up to 12% under prolonged stress exposure (over 24 hours), which is typical for Canadian logistics routes. The study provides a detailed analysis of the biochemical mechanisms underlying the formation of meat quality defects such as PSE (Pale, Soft, Exudative) and DFD (Dark, Firm, Dry), resulting from disruptions in animal homeostasis. It was found that financial losses associated with technological defects and reduced water-holding capacity of meat are 25.8% higher than direct losses caused by live weight reduction. According to projected calculations based on wholesale producer prices, total annual losses in the Canadian agricultural sector due to inefficient logistics protocols exceed 2 billion CAD. The scientific novelty of the study lies in substantiating the identification of the transport stage as a Critical Control Point (CCP) within the food safety management system based on HACCP principles. Key monitoring parameters (transit time, temperature conditions, and pH levels) are defined, enabling the integration of IoT sensor data into digital HACCP frameworks. A comparative analysis of EU practices demonstrates the effectiveness of strict transport time regulations (up to 8 hours) in minimizing chronic stress in cattle, while also highlighting the risk of acute stress in pigs due to frequent unloading (EFSA Panel on Animal Health and Welfare, 2022). The practical significance of the study lies in the development of recommendations for modernizing logistics through electrolyte support systems and intelligent climate control technologies, thereby enhancing product quality and export potential.
