Study On Analysis Of Biological Hazards Associated With Compound Feed Producing In Relation On Food Safety

Compound feed and raw materials are potential vectors of pathogenic bacteria and potentially toxigenic fungi. The paper conducts a study on the production of compound feed in relation on food safety, by mycological and bacteriological analysis of samples of raw materials and compound feed for broilers, taken from a feed mill from Romania during 2019. Methodologically, the data were processed, analyzed and synthesized in the form of graphs and tables. The obtained results highlight during the analyzed period, in the samples of mycologically analyzed raw materials, eight genera of potentially toxigenic fungi were identified; the largest presence was the genus Aspergillus (64.45%). In the analyzed compound feed samples, four potentially toxigenic fungal genera were identified; in the samples with quantifiable results, the majority (61.9%) was identified the genus Aspergillus, and the lowest presence was the genus Cladosporium (9.53%). All results of bacteriological analysis aimed at determining the contamination with Salmonella spp. (54 analyzes for raw materials and 105 for compound feed) and E. coli (51 analyzes for raw materials and 101 for compound feeds) were negative. It can be concluded that in the production process of compound feed, the mycological, bacteriological and mycotoxicological analysis is must both for raw materials susceptible to contamination and of the finished products obtained; this goal is achieved in the unit studied, the results highlight the effectiveness of specific food safety control processes.
