Supermarket giant Woolworths has announced it will phase out the sale of caged eggs by 2018. FARMERS are upset over Woolworths' decision to phase out the sale of eggs from caged hens over the next five years. The supermarket giant says it will drop caged eggs by 2018 amid growing consumer pressure to address animal welfare concerns, but Coles and other grocers have not yet announced similar sweeping bans. Caged eggs will no longer be used as an ingredient in Woolworths home brand products and hen stocking density will be displayed on its free range egg brands. The announcement is expected to affect 12 Woolworths caged egg suppliers that will be forced to change to a cage-free system. Victorian Farmers' Federation egg group president Brian Ahmed says the move would be costly for farmers. "As an industry, it's very upsetting," Mr Ahmed said. We have invested in new cage systems that meet industry requirements and now, five years later, they want to ban cages with no compensation for farmers. Mr Ahmed said farmers would be forced to change their systems to continue to be a part of the egg industry and that free range eggs may be unaffordable for some consumers. Woolworths spokesman Lyndsey Gordon said the company would work with farmers to lower the cost of barn-laid eggs. "We will work closely with the industry over the next five years to improve efficiencies and minimise cost," he said. Animals Australia campaign director Lyn White called the decision a win for animals and consumer power. Coles announced it would stop selling its company-branded caged eggs in October last year. Coles spokeswoman Jackie Healing said the company had also removed caged eggs and sow stall-produced pork from its Coles brand product range. The company continues to sell caged eggs from other suppliers. An Aldi Australia spokesperson said the supermarket chain had no plans to phase out caged eggs. "We do not have any current plans to change our business practices with regards to caged eggs and no decisions on this matter will be made without industry consultation," an Aldi statement said. All eggs sold at Aldi have packaging that details the living conditions of cage, barn or free range hens.
