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.
