'factory-farmed' originates from the combination of 'factory' and 'farmed,' where 'factory' refers to a large industrial operation and 'farmed' refers to the practice of raising animals or growing crops.

'factory-farmed' evolved from the concept of 'factory farming,' which became prevalent in the 20th century as agricultural practices shifted towards industrialization.

Initially, it referred to the method of farming in factories, but over time it evolved to emphasize the negative aspects of industrial farming, particularly concerning animal welfare.
