At peak the Blayney Abattoir employed about 1,600 people, one of the largest workforces in Central West New South Wales. The site had been a butter factory and freezing works from at least 1900, converted to an abattoir in 1957. ANZCO Foods, the New Zealand owner since 1996, announced closure in March 1998 with about 600 workers given a week's pay.
The plant ran on multiple floors, one per species. The mutton floor carried two chains, the larger processing 3,000 to 4,000 sheep a day and the smaller around 1,500. Beef ran at 250 to 400 cattle a day and pig at around 400; cold stores, holding pens, boning rooms and packing rooms filled out the rest of the building.
At full daily capacity the plant could handle around 5,500 sheep, 350 cattle and 400 pigs, sent into domestic and export markets. ANZCO's purchase fit a trans-Tasman meat industry consolidation pattern through the 1990s. The company cited stock shortage as the reason for closure; the Australian Meat Industry Employees' Union named economic factors, with the Asian financial crisis sitting in the trade-press background.
In the weeks before final shutdown the workforce had fallen from 1,600 to about 100. The plant has stood disused since 1999. A major project listing on the NSW Planning Portal records that redevelopment of the site has been formally considered through the state planning system; current status is unconfirmed.
