Abstract
This study investigates seasonal trends and correlations among different mycotoxins in animal feed, employing time series analysis and Seasonal-Trend Decomposition using LOESS (STL) to uncover patterns and relationships. Data collected from Food Fortress, covering 2014 to 2024, includes feed for ruminants, pigs, and poultry. The analysis reveals that seasonality accounts for less than 15% of the variability in mycotoxin levels, suggesting a limited seasonal influence. High deoxynivalenol (DON) concentrations in ram feed were attributed to specific management practices, while persistent DON levels in pig and poultry feed highlight the need for enhanced interventions. A strong correlation between DON and zearalenone (ZEN) was identified in pig and poultry feed. Over the study period, aflatoxin levels exhibited a slight increase, potentially linked to evolving climatic conditions, whereas DON and ZEN levels showed a slight decline. Furthermore, an inverse correlation between aflatoxin and ochratoxin levels suggests competitive interactions among fungal species, such as Aspergillus and Penicillium. These findings provide valuable insights into the intricate interactions of seasonal factors, management practices, and fungal ecology shaping mycotoxin contamination in animal feed. The study emphasizes the need for advanced mitigation strategies, including predictive modeling and artificial intelligence, to monitor and manage mycotoxin risks effectively at regional level, ensuring feed safety and quality in the face of evolving environmental and management challenges.
期刊介绍：
The Journal of Food Protection® (JFP) is an international, monthly scientific journal in the English language published by the International Association for Food Protection (IAFP). JFP publishes research and review articles on all aspects of food protection and safety. Major emphases of JFP are placed on studies dealing with:
Tracking, detecting (including traditional, molecular, and real-time), inactivating, and controlling food-related hazards, including microorganisms (including antibiotic resistance), microbial (mycotoxins, seafood toxins) and non-microbial toxins (heavy metals, pesticides, veterinary drug residues, migrants from food packaging, and processing contaminants), allergens and pests (insects, rodents) in human food, pet food and animal feed throughout the food chain;
Microbiological food quality and traditional/novel methods to assay microbiological food quality;
Prevention of food-related hazards and food spoilage through food preservatives and thermal/non-thermal processes, including process validation;
Food fermentations and food-related probiotics;
Safe food handling practices during pre-harvest, harvest, post-harvest, distribution and consumption, including food safety education for retailers, foodservice, and consumers;
Risk assessments for food-related hazards;
Economic impact of food-related hazards, foodborne illness, food loss, food spoilage, and adulterated foods;
Food fraud, food authentication, food defense, and foodborne disease outbreak investigations.
