Abnormal behavior, such as tail biting, is a fundamental problem in pig husbandry worldwide, and the application of enrichment materials, particularly organic materials, is one of the most promising preventive and curative measures. However, the potential health risks posed by these materials, such as being an additional source of mycotoxins, have not been sufficiently studied to date. Therefore, 21 different organic enrichment materials were tested for mycotoxin contamination with a liquid chromatography tandem mass spectrometry multi-mycotoxin method. Concerning the legally regulated mycotoxins in the EU, aflatoxin B1 and ochratoxin A were not detected in any of the tested materials. Fumonisin B2 was detected in straw meal made of wheat, rye, and triticale, but the level (0.014 mg/kg) was very low. The level of deoxynivalenol in maize pellets (5.01 mg/kg) and maize silage (2.12 mg/kg) exceeded the guidance value for pig feed. Zearalenone was present at high levels in maize pellets (1.21 mg/kg), hay (0.30 mg/kg), and maize silage (0.25 mg/kg). Maize products showed high levels of mycotoxins presenting a health risk for pigs and cannot be recommended as enrichment material.
