Food safety hazards associated with compound feed can be physical, chemical and biological. The paper aims to conduct a study during 2019 and 2020, on the production of compound feed in relation on food safety, by physical analysis of samples of raw materials (corn grains, wheat grains) used in the production of compound feed from two feed mills from Romania, called in the paper "unit A" respectively "unit B". Regarding the hazards identified in unit A, it was found that in 2019, 20 lots of corn grains (68.9%) and 9 lots of wheat grains (31%) were refused, the most common hazard identified (78.5%) being represented by their high humidity. In 2020, 17 batches of raw materials were rejected, represented by corn grains (52.9%) and wheat grains (47%); humidity was also the predominant potential hazard identified (70.5%). In the case of unit B, based on physical parameters, in 2019, 22 batches of corn grains (91.6%) and two batches of wheat grains (8.3%) were refused; the most frequently identified hazard (58.3%) was the presence of sprouted and moldy grains. In 2020, 53 batches of raw materials were rejected, represented by corn grains (79.2%) and wheat grains (20.7%); the most frequently identified hazard was beetle infestation (50.9%). It can be concluded that in the production process of compound feed it is mandatory the physical analysis of raw materials to determine potential hazards; this goal is achieved in the units studied, the results highlighting the effectiveness of specific food safety control processes.
