Summary
The study found that AFCF significantly reduced cesium-137 ((137)Cs) levels in broiler and pheasant meat. AFCF mixed with feed was most effective, lowering (137)Cs by up to 22 times.
Area of Science:
- Environmental Science
- Radiological Protection
- Animal Science
Background:
- Cesium-137 ((137)Cs) contamination poses risks to poultry meat safety.
- Protective agents are explored to mitigate radionuclide uptake in food animals.
- Understanding radionuclide distribution in poultry meat is crucial for food safety assessments.
Purpose of the Study:
- To evaluate the efficacy of two protectors, AFCF and clinoptilolite, in reducing (137)Cs accumulation in broiler and pheasant meat.
- To investigate the distribution of (137)Cs in leg and breast meat of poultry after contamination.
- To compare the effectiveness of protectors administered via gastric tube versus mixed in feed.
Main Methods:
- Broilers and pheasants were experimentally contaminated with a single dose of (137)CsCl.
- Two protectors, AFCF and clinoptilolite, were administered either via gastric tube or mixed with feed.
- Cesium-137 concentrations in leg and breast meat were measured and compared to control groups.
Main Results:
- AFCF significantly reduced (137)Cs concentrations in both broiler and pheasant meat, with greater efficacy when mixed in feed (up to 22.1-fold reduction).
- Clinoptilolite showed a moderate reduction in (137)Cs levels (1.4 to 2.9-fold reduction), with lower effectiveness compared to AFCF.
- AFCF administered via gastric tube also demonstrated substantial reduction in (137)Cs levels (up to 13.7-fold).
Conclusions:
- AFCF is a highly effective agent for reducing (137)Cs accumulation in broiler and pheasant meat.
- The method of administration (mixed in feed vs. gastric tube) influences the protective efficacy of AFCF.
- Clinoptilolite offers limited protection against (137)Cs contamination in poultry meat under the studied conditions.
