This study aimed to evaluate the frequency and concentration of mycotoxins in pig feed and its raw materials in the upper region of El Oro Province, Ecuador. A descriptive longitudinal observational study was conducted between 2020 and 2024, using ELISA techniques to detect aflatoxins, fumonisins, and zearalenone in samples of wheat bran, maize, soy, rice polishings, broken rice, wheat, rice cone, and pig feed across different production phases. The results showed a high occurrence of zearalenone in soy (88%), rice cone (100%), wheat (90%), and wheat bran (95%), highlighting the susceptibility of these ingredients to Fusarium spp. contamination. In pig feed, the lactation phase showed an occurrence of 86%, while the development phase reached 100% prevalence. Regarding aflatoxins, maize exhibited a contamination range of 0.0 – 20.5 μg/kg, aligning with previous studies indicating its high susceptibility to Aspergillus flavus in tropical regions. However, fumonisins had the highest concentrations, with a range in maize of 0.0 – 12,570 μg/kg and an occurrence of 94%. In pig feed, the development phase showed the highest concentration, reaching 5,020 μg/kg. It is concluded that mycotoxins pose a significant risk to pig feed safety and public health, as their accumulation in the food chain can affect both animals and human consumers. The implementation of monitoring programs and control strategies in pig feed production is essential to reduce exposure to these compounds and mitigate their adverse effects on animal health, productivity, and human health. |
