[QUOTE="Lucky_P, post: 1514299, member: 12607"] No issue with regard to safety of beef from an animal that's seropositive for anaplasmosis. Yes, I change needles. Have discussed it here on numerous occasions. I do re-use syringes for administration of the same vaccine/medication to multiple animals. Any cow born here after 2007, and any heifer which has the slightest possibility of staying as a replacement ALWAYS gets her own new, sterile needle each time we 'work' them.... I may reuse needles on the SAME animal... for instance, giving a mlv, then switching that needle over to a syringe containing a dose of Clostridial or Lepto bacterin... but a needle that's been in an animal never goes in and out of a bottle of vaccine or medication, and for the most part... not into another animal. I will reuse needles on steers and heifers I'm not retaining... because someone will be eating them before BLV (MY concern, but if I had anaplaz in the herd, it would be consideration #1) would be a problem. A clinically-ill Anaplasmosis cow will likely die without treatment... she'd likely never make it through the salebarn. IMO, there's a huge difference in sales from seedstock producers and folks just running cattle through the local salebarn, but I don't see a positive test result as a need to kill and incinerate. If you have anaplasmosis in your herd... or you're in an endemic area and your herd is at high risk... vaccination is the way to go, IMO. I know some of the folks here on CT live and die with salebarn cattle... personally, I would never consider buying an animal at the salebarn and taking it home... Maybe I'm wrong, but in my eye... if it's at the salebarn... there's a reason it's there, and I don't want it on my place. With the exception of steers and feeder heifers that weren't good enough to stay (or, maybe they were crazy, etc.)... anything that leaves here probably needs to be going straight to slaughter... but I don't influence that, other than telling them... 'she's open' or, 'she's bred'. If someone's buying my stuff at the barn... it's 'caveat emptor'... I'm not selling something that I know is gonna die in the next week... but I wouldn't hesitate to sell a 'healthy' cow that's BLV- positive... or maybe even Anaplas-positive... I don't have to face the dilemma, as I don't have anaplasmosis in my herd... but I'm not sure whether I'd announce positive/negative status on a cull cow going through the local salebarn or not... if you're buying at the salebarn, I figure you're a big boy and you can take your chances. I've sometimes suggested... and not necessarily jokingly... that if someone is testing their (commercial) herd for anaplasmosis titers, and they're finding a high percentage of positives... they might need to consider selling all the test-negative animals and keeping the positives! Those negative animals are at risk of becoming infected and dying; the positives are not... but they can serve as a source of inoculation for ticks that could transmit it to naive animals. Calves born to those positive cows probably have a pretty reasonable likelihood of being infected early in life... becoming chronically-infected animals that also will never become clinically ill... but can serve as a reservoir for infection. Valuable seropositive animals that you feel 'must' be restored to test-negative status can potentially be cleared by feeding high levels of CTC (2mg/lb body wt/day) for 60 days or so. It may take 3-6 months for their titer to drop back to 0... and they are susceptible to reinfection. [/QUOTE]
