Twenty three Pennsylvania dairy farms were evaluated for stray voltage in a project sponsored by the Pennsylvania Department of Agriculture in 2001. An action level of 1 volt, with a 500 ohm resistor, at cow contact points was selected. All the farms had typical symptoms attributable to stray voltage but most of them were not caused by stray voltage. Because stray voltage was believed to be the cause of their problems, the farms were not investigating other management, equipment or cow health issues. It was also determined that there was no consistent procedure for evaluation or mitigation of stray voltage. Seven recommendations are included in the report. Two important actions suggested are: 1) Establish a standard method for testing for stray voltage and a standard action level where mitigation is indicated to reduce confusion on Pennsylvania farms. 2) Form a statewide task force or committee, representing all interested parties, to adopt standards and address continuing stray voltage issues.
