Animal rights advocates will gather on Beacon Hill in Boston to press lawmakers on a proposal that would ban the sale of food products from farms that keep animals in small, restrictive cages.
The proposal would effectively prohibit the sale of eggs, pork and veal from animals kept in the tight spaces, wherever they are raised.
Supporters have already collected enough signatures to place the question before voters on the November ballot.
Critics say the measure could drive up the price of eggs in Massachusetts, most of which come from farms outside of the state.
Thursday's hearing before the Legislature's Committee on Environment, Natural Resources and Agriculture will give lawmakers the chance to consider approving the measure before November.
The hearing begins at 1 p.m. at the Statehouse.
