Mycotoxins, heavy metals and pesticide residues in Croatian cereals

The quality and safety of cereals is of great importance since they still are the world’s most important source of food and feed. Cereal safety can be endangered by numerous contaminants, including biological, chemical and physical, which can entry into the food chain during food and feed production, storage and transport. Treatment of crops with pesticides may leave residues in products of plant and animal origin. Natural contaminants, such as mycotoxins, may also appear in food and feed, while heavy metals are introduced into products through water, air or soil. The toxicological relevance of above mentioned contaminants and residues is well established, however the total health impact of combined exposure to various pesticide residues, heavy metals and mycotoxins remains unknown. Monitoring the incidence of these pollutants is crucial for health risk assessment, especially if considering the possibility of their synergistic effect. As systematic investigations of their occurrence in Croatian cereals are still lacking, this research aims to monitor the contamination level of nation-wide crops by mycotoxins, heavy metals and pesticide residues. All major cereals grown in Croatia (corn, wheat, barley) and products thereof were collected from all Croatian counties. Regulated mycotoxins were determined by “dilute and shoot" method using highly sensitive LC-MS/MS. Heavy metals were analysed by microwave digestion and AAS, while pesticide residues were determined using QuEChERS sample preparation and both LC-MS/MS and GC-MS/MS. All used methods were validated and legislation criteria requirements assured. The highest mycotoxin incidence was found in corn samples, where the most of regulated mycotoxins were present. Fusarium mycotoxin deoxynivalenol was observed to be the most frequent mycotoxin in all collected samples, having the concentration above LOQ in 40.8% of samples. Mycotoxin concentrations higher than allowed were observed in 9 corn samples. Pesticide residues and heavy metals were determined in the most significant samples taking into account the heterogeneity of samples contamination by mycotoxins (high or low level). The obtained data pointed out the higher incidence of mycotoxins rather than other two contaminant groups, however the importance of consistent control of all three stated contaminants in different foodstuffs and feedstuffs should not be overlooked.
