Change Needles For Good Beef Quality Assurance

Ben Schroeder, DVM, Cedar County Veterinary Services, Hartington, Neb., explains why he supplies his producers with a full box of needles instead of just what they might need, in order to help them maintain BQA principles when vaccinating cattle.


VAHS Needle and Syringe Standard Operating Procedures

Multi-dose syringes should be clean and maintained in good repair.  Use syringe sizes appropriate to the volume of the injection.  Disposable syringes should be discarded at the end of the day.   Use clean needles and change needles after every 10-15 head or if the needle is dull or burred.  Clean vaccine transfer needles weekly in hot tap water (no soap or disinfectant) and then place transfer needle in a cup of water (completely cover with water throughout process) and microwave on high for 1 minute.  Air-dry and store in a clean ziplock bag. At the end of the day multi-dose syringes used for vaccines should be rinsed 5 times with clean, very hot water.  Wash the external surface with Hibitane, water and a brush.  At weekly intervals the plastic barrel should be removed and the barrel and “O” rings brushed with a clean bottlebrush and then rinsed 5 times with hot water.  Do not use disinfectants in vaccine syringes.   Syringes used for antimicrobials should be disassembled at weekly intervals and washed with hot water and Chorhexidine disinfectant and then rinsed well.  Use appropriate lubricants for syringes.  This can be lubricants provided with syringes or vegetable oil.  DO NOT use mineral oil as this will damage the rubber “O” rings.
