Sulfapyridine is a widely used sulfonamide antibiotic that effectively prevents and treats animal diseases. It is known for its significant therapeutic effects and affordability [104105]. However, the slow metabolism of this antibiotic in animals can lead to its accumulation, and consumption of poultry meat containing antibiotic residues can pose a risk to human health [106]. China's "National Food Safety Standard for Maximum Residue Limits of Veterinary Drugs in Food" (GB 31650-2019) sets the maximum residue limit (MRL) for sulfonamide drugs in animal-derived food at 0.1 mg/kg.

Currently, the detection of Sulfapyridine residues commonly involves liquid chromatography, enzyme-linked immunosorbent assay, and fluorescence detection. However, these methods present several challenges such as complex pre-treatment procedures, lengthy detection times, high sample demands, and sample loss. Therefore, Surface-enhanced Raman spectroscopy offers a simple, rapid, and traceless alternative to detect Sulfapyridine at low concentrations
