A word for a place that produces food from animals
Solution 1:
High-processing packinghouse
is the term you're looking for.
Here are the distinctions made in the Netherlands for all type of meat processing plants, from a governmental website.
Categories of slaughter-plants
Plants for red meat slaughtering may be categorized on the basis of the final products. A plant that processes meat into products such as canned, smoked and cured meats is significantly different from a plant with facilities for slaughtering without further processing.
Slaughterhouses and packinghouses (slaughtering and meat processing) may each be divided into two categories on the basis of the quantity of waste produced (EPA 1974).
Slaughterhouses:
- Simple slaughterhouse:
A plant that slaughters animals and does a very limited amount of by-product processing. Its main products are fresh meat in the form of whole, half or quarter carcasses or in smaller meat cuts.
- Complex slaughterhouse:
A plant that slaughters and does extensive processing of by-products. Usually at least three of the following operations take place: rendering, paunch and viscera handling, blood processing, and hide and hair processing.
Packinghouses
- Low-processing packinghouse:
A plant that both slaughters and processes fresh meat into cured, smoked, >canned and other meat products. Only the meat from animals slaughtered at the plant is processed. Carcasses may also be sold.
- High-processing packinghouse:
A plant that also processes meat purchased from outside. Sometimes, a high- >process packinghouse has facilities for tanning operations.
There are also plants that do not slaughter themselves but restrict their activities to the processing of meat (meatpacking). These plants have a waste production comparable to that of a simple slaughterhouse.
It's also the official name in the US see this extract from Cornell Law School
For the purpose of this subpart: High-processing packinghouse means a packinghouse which processes both animals slaughtered at the site and additional carcasses from outside sources.
Solution 2:
The UK National Careers Service gives these categories of workplaces and employee roles, which suggest how things are generally split up here.
- abattoirs – as a slaughterman or woman, humanely killing and preparing livestock
- wholesale meat factories – cutting, de-boning and preparing carcasses before they are sold to retailers
- butcheries – specialising in preparing meat in line with instructions from caterers
- meat or poultry processing plants – producing and packing products for the retail and catering industries
I'm not sure that we have one term which covers all eventualities. Individual establishments will also carry out different parts of the processing. My local abattoir calls itself an 'abattoir and cutting plant' and does basic butchery for small livestock producers who take in live stock and collect the boxed up bits a few weeks later after the meat has hung and been butchered, but other establishments will only take larger jobs and ship out as soon as the carcass is skinned and cleaned.
Solution 3:
Probably "meat packing plant" comes closest in the US, as it implies all stages of the preparation. "Slaughterhouse" could be interpreted as referring to only the front-end slaughter operation (though I vaguely recall that this is referred to as the "kill room" in the Hormel operation about 50 miles southwest of here).
