Abstract: The Food Safety Law of 2009 and the revised Agricultural Product Quality Safety Law of 2023 both explicitly prohibit the use of lean meat enhancing agents（β ⁃ adrenergic receptor agonists such as clenbuterol， ractopamine，and salbutamol） and mandate compulsory testing during the slaughtering process. The Ministry of Agriculture and Rural Affairs also requires hog slaughtering enterprises to implement the regulation of“pre⁃slaughter testing，”with the testing ratio typically set at 5% to 10%（subject to regional variations）. Under the strict supervision and implementation by various departments，the pass rate of recent sampling inspections has consistently remained above 99%. Given that the positive rate of clenbuterol has long been at an extremely low level and testing costs are high，this study focuses on optimizing the testing ratio for clenbuterol in the hog slaughtering process. It will systematically analyze the current testing situation，policy controversies，scientific basis for ratio adjustments，and optimization suggestions，exploring the necessity and feasibility of dynamically adjusting testing intensity and improving regulatory efficiency while maintaining safety standards.
