The presence of unacceptable levels of veterinary drug residues in animal-derived food is a global concern due to its negative impacts on human health. This study reports the occurrence and levels of two fluoroquinolone antimicrobialsenrofloxacin and ciprofloxacin-in broiler meat sold in Sri Lanka. A total of 129 broiler meat samples were purchased from the market, representing nine large-scale broiler meat processors (107 samples in 66 batches, branded) with an islandwide distribution and 22 small-scale processors (22 samples, unbranded). Enrofloxacin and ciprofloxacin in breast muscle were extracted following a previously published method with modifications and were subjected to High-Performance Liquid Chromatography with Fluorescence Detection analysis for the quantification of antimicrobials. Enrofloxacin residues were detected in 67 (51.9%) samples, out of which 28 had quantifiable levels (1.7-578.6 μg kg -1 ), whereas ciprofloxacin was detected in only nine samples. Only three samples (2.3%) exceeded the European Union maximum residue limit of 100 μg kg -1 for the sum of ciprofloxacin and enrofloxacin in poultry muscle. These three samples had enrofloxacin in 130.3-578.6 μg kg -1 range and ciprofloxacin in 15.7-28.8 μg kg -1 range. Mean enrofloxacin level in other samples was 5.9 ± 5.3 µg kg -1 . This study shows the widespread use of enrofloxacin in broiler meat industry in the country and the possibility of meat with harmful levels of residues entering the market. Thus, we highlight the need to establish regulations and a national-level veterinary drug residue surveillance program for animal-derived foods including broiler meat to ensure consumer safety.

Pyloric stenosis, which could occur as a congenital or acquired condition, is more common in dogs when compared with other domestic animals. This condition has not been reported in Sri Lanka probably due to unfamiliarity with it and lack of diagnostic facilities. This communication discusses the clinical signs, radiographic and ultrasonographic findings, and treatment of pyloric stenosis in a one-year old female Cocker Spaniel presented to the Veterinary Teaching Hospital (VTH), Peradeniya. The patient developed projectile vomiting and distended, gas filled abdomen after meals as clinical signs. Survey radiographic findings included the 'gravel sign' in the stomach. In ultrasonography, thickened pylorus was observed. Contrast radiographs after oral administration of barium sulphate suspension showed a delay of gastric emptying. All the above findings suggested that the patient had pyloric stenosis. Complete blood count and serum biochemistry demonstrated no abnormalities. Surgical intervention was performed as treatment, using Fredet-Ramstedt pyloromyotomy together with Heineke-Mikulicz pyloroplasty to clear the obstruction in the pyloric canal. Since there were no post-surgical complications, patient was discharged in 4 days following the surgery. The prognosis was satisfactory and the animal has been healthy after the surgery. The pyloric stenosis observed in this case could be congenital, with hypertrophy and subsequent stenosis gradually worsening over time.
