A private members' bill that is supposed to protect farmers, their families and their livestock from electrical current in the ground has unanimously passed second reading in the Ontario legislature.

Chatham-Kent-Essex MPP Rick Nicholls says ground current pollution is the byproduct of running too much current through transmission lines.

He says the excess moves through the soil and it's having a detrimental effect on livestock and dairy production.

The bill goes to committee next for further study.
