Most reports indicate that the drags are most effective when used preventively. Once a positive diag nosis is made, your veterinarian and laboratory can assist you in selecting the most effective drug. Prevention All-in, all-out management, including cleaning and disinfec tion, helps but not as effectively as it does for other diseases. • Move affected pigs to a sepa rate pen if practical, especially if diarrhea is the main symptom. This will help reduce the spread of the disease. • If buying feeder pigs, buy from a single source and avoid the sale bam whenever possible. • Treating newly purchased pigs with an appropriate antibiotic and dewormer will reduce the inci dence of Salmonella. • Avoid overcrowding. • Vaccination is an option since a few commercial products are available, however most practi tioners have not had good success. Best results are obtained with vac cine products that contain only Salmonella. And it’s possible that an autogenous vaccine may need to be developed specific fra* your operation. Summary 1. Salmonella is an organism that can be found on virtually every swine operation. Many of the serotypes are of little consequ ence, but there are three types than can cause serious disease in pigs, the most common of which is S. cholerasuis. 2. S. cholerasuis can cause diar rhea and pneumonia as well as other problems for pigs from the nursery through die finishing stage. 3. Work with your veterinarian and diagnostic laboratory to obtain a clear diagnosis and treatment plan. 4. Prevent the disease by mini mizing stress sort pigs as little as possible, buy feeder pigs from a single source, and use all in all out management References Fleming, B. 1992.

Issues Set Tone Senate Ag and Rural Affairs Com mittee. A Voluntary Whole Farm Program to be presented by the Family Farm Movement was endorsed at the county level, which includes provisions for allowing farmers to have final decision making on nutrient man agement legislation introduction, review, and implementation. The proposals are to combat cocems about the review of H.B. 496, which the county association believes had left out farmers at the decision-making level, which makes programs mandatory to far mers regardless of costs, and involves no tax-paying public involvement. The current bill, according to the county farmers association, “allows farmers to be trapped between competing gov ernment agencies involved in plan ning and implementation.” According to the resolution, if the Voluntary Whole Farm Prog ram were adopted, farmers would be allowed to participate “under a one-plan concept with one agency to contact for plan development and implementation.” It would require 100 percent of the cost to Lancaster Farming, Saturday, Octobar 17,1M2-D7 Meeting be shared with tax-paying public to ensure that technology, education, and economics drive die program. Other policies recommended include a proposal to allow deer that are raised for venison or breeding stock be treated under state law as all other farmed lives tock, with pertinent bill amend ments; the Pennsylvania Farmers Association legal department should write contracts for farmers who do contract farming that would protect the farmer from being dominated by the agribusi ness; a farmer classified as self employed should be able to use their entire health insurance pre mium as a tax deduction; and a recommendation for a current law to require employers to carry workman’s compensation to be abolished and be replaced with a law that would require employees to carry their own accident policy. Also at the banquet meeting, the following district directors were elected: District 2, Ike Geib; Dis trict 3, Marvin Witmer; District 5, Earl Newcomer; District 9, Robert Best; District 10, Dale Marlin; District 11, Willis B.
