Assessing Cadmium Levels in Horses Imported from the European Union and Slaughtered in Italy.

This research article studies the concentration of cadmium, a toxic heavy metal, in horses imported to Italy from other European Union countries. It also examines the relationship between cadmium levels and related lesions in the horses’ tissues and organs. The findings highlight a potential food safety concern.

Objective of the Study

• The study aims to assess the concentration levels of cadmium (Cd) in horses imported from different European Union countries and slaughtered in Italy.
• Another objective is to find any correlation between Cd levels and Cd-related gross and histological changes in tissues and organs of these horses.

Methodology and Findings

• The research team classified the animals into six groups based on their age and geographical origin.
• Out of all 430 horses studied, the team found gross renal kidney lesions in only two cases, seen in horses from Poland, exhibiting the highest Cd concentrations of 9.1 mg/kg w/w and 8.23 mg/kg w/w respectively.
• Further histological changes were discovered in the same group, particularly in 19 kidney samples which showed Cd concentrations exceeding 5.72 mg/kg w/w.

Implications on Health and Food Safety

• The findings of this study are critical as they raise potential food safety concerns. According to Regulation (EC) No. 1881/2006 and subsequent amendments, there are strict maximum limits for Cd in horse meat and offal. These measures are taken to prevent the harmful effects of Cd when consumed by humans, that could lead to serious health issues like cancer and organ damage.
• The results emphasize the need for integrating chemical analyses with histological examinations for a comprehensive assessment of risks. This approach can ensure compliance with EU food safety legislation and international trade standards, upholding the European Union’s precautionary principle for food safety.
