Where does pork come from?

China's pork output fell by about as much as the whole world's in 2019. China reported 54.0 million tonnes in 2018 and 42.6 million tonnes in 2019, a fall of 21%, and that 11.5 million tonne drop was larger than the world's 10.9 million tonne drop, so output elsewhere rose that year (our arithmetic on FAOSTAT, sum of countries). China produced 46% of the world's 125.3 million tonnes in 2024 (FAOSTAT), so the world total moves with China's reported figure. The 2019 fall came the year after the August 2018 confirmation of African swine fever in China, recorded in this page's timeline (WOAH); the output series alone does not establish the cause.

Four fifths of Mexico's imported pork comes from the United States, which in turn sends Mexico over a third of its pork exports. In 2024 the United States sold $2.35 billion of pork to Mexico, the largest bilateral route in the trade, and Mexico took 36.1% of US pork exports (our arithmetic on CEPII BACI bilateral flows; see trade flows). The United States supplied 80.7% of Mexico's pork imports that year (CEPII BACI), and Mexico's 1.28 million tonnes of imported pork equalled 68% of its reported 2024 output of 1.9 million tonnes (our arithmetic on CEPII BACI product weight and FAOSTAT carcass weight, so the ratio is indicative).

Spain and Canada sell abroad a far larger fraction of their pork than the United States does. In 2024 export weight was about 47% of reported output for Canada, 37% for Spain and 18% for the United States, against 71% for Denmark (our arithmetic on CEPII BACI product weight against FAOSTAT carcass weight, so the ratios are indicative, not shares of output). The United States ranked second in output with 10% yet first in export value with 18% (CEPII BACI and FAOSTAT, 2024).

In 2024 China produced 57.1 million tonnes, 46% of the world's 125.3 million tonnes (FAOSTAT). United States followed with 10%, then Brazil (4.3%), Spain (4%) and Russia (3.9%). The top five account for 68%, 171 countries reported output and 21% came from outside the top ten. World production changed +8% over the ten years to 2024 and +1% on the previous year.

A pig turns grain into meat faster and more efficiently than cattle and needs housing rather than land, so production concentrates where feed is cheap and where people eat pork. That puts the herd in China, the United States corn belt, Brazil and the pig belts of Spain, Germany and Denmark, close to feed mills rather than to grazing.

The figures count pig meat with the bone on a carcass basis, which is how the trade weighs it. Consumption is concentrated too: pork is the most eaten meat in China and the European Union, while religious restriction removes much of the Middle East, North Africa and South Asia from the market entirely.

United States was the largest exporter of pork (HS 0203) in 2024 with 18% of world export value, ahead of Spain (17%), on world trade of $37 billion (CEPII BACI). Japan was the largest importer with 11%.

The largest producer also buys from abroad, which looks contradictory and is not. China's herd swings hard with disease and policy, and imports fill the gap while it is rebuilt; feet, ears and offal that earn little in western markets are worth carrying halfway around the world to Chinese buyers.

Pork is traded cut by cut rather than as carcasses. Italy buys legs for curing, Japan and South Korea chilled cuts at a premium, Mexico hams and shoulders for processing. Each part of the animal is sold into the market that values it most, which is why export earnings and export tonnage rank countries differently.

There is no pork price on this page. Lean hog futures are traded in the United States and cash settled to a reported carcass index, and this site does not carry them; no global pork benchmark exists at all, because disease status splits the world into markets that cannot trade with each other. Pigs are sold instead on packer contracts, most of them formula-priced off officially reported cash sales and off carcass grading for weight and lean meat percentage.

The visible references are government market reports: weekly reference prices for pig carcasses in the European Union, daily reported negotiated and formula purchases in the United States, and the cut-out values that packers publish for primal cuts. Producers not on a formula sell into regional spot markets or cooperative pools, and the gap between two national prices can persist for years, since a ban keeps meat from moving to where it is dear.

There is no effective commercial vaccine, mortality approaches total in infected herds, and outbreaks trigger culling and import bans. It has repeatedly removed a large share of a national herd within months, and rebuilding takes a year or more because breeding sows must be produced first.

Corn and soybean meal make up most of the cost of raising a pig, so grain markets pass through to hog prices within a season. When feed is dear, producers cut sow numbers, which tightens pork supply about a year later, long after the grain price has moved on.

Roughly ten to eleven months separate the decision to breed a sow from a market hog, so production responds to today's price with a long lag. That delay produces the classic hog cycle of overshoot and correction, which is visible in every producing country's history.

Access depends on veterinary status, not price. A single confirmed outbreak can close an export market overnight, and reopening it takes negotiation over regionalization, so trade flows redraw themselves around disease maps rather than around cost of production.

A pig arrives as a whole animal, and its value depends on selling every part. When demand for offal, fat or particular cuts weakens in one market, the packer either finds another buyer or discounts the whole carcass, so the price of pork in one country depends on appetites in another.

A breeding herd of sows produces litters that are weaned at three to four weeks, grown on in nursery barns and finished on a cereal and oilseed meal diet, reaching slaughter weight at around six months. Genetics, feed formulation and housing are managed to a target lean meat percentage, because that is what the carcass will be graded and paid on.

At the plant, animals are stunned, dressed and split, and the carcass is chilled overnight before being graded and broken into primal cuts. Chilling is what makes the rest of the chain possible: chilled pork moves within a region and a short window, while frozen pork travels between continents.

Further processing takes a large share of output. Bellies are cured and smoked into bacon, legs are salted and dry-cured into hams that mature for months or years, trimmings are ground into sausage.

Most pork is eaten fresh or processed, and processing matters more here than in other meats: cured hams, bacon, sausage and cooked products take a large share of consumption.

The by-products are extensive. Fat is rendered into lard and industrial tallow, skin and bone yield gelatin and collagen for food and pharmaceuticals, blood goes to plasma proteins and feed, and bristles to brushes. Intestines are the source of heparin, an anticoagulant with no easy synthetic substitute, and pig tissue is used in surgical grafts and heart valves, so a share of the animal ends up in medicine rather than food.

The chain runs from feed mill to barn to packing plant, and the packing plant is the choke. Slaughter capacity is concentrated in a small number of very large, labor-intensive plants, and pigs cannot wait: they keep growing on schedule, so when a plant stops, animals back up behind it within days and the loss is immediate and irreversible.

Beyond the plant, the chain splits by temperature. Chilled pork serves nearby markets on a short clock and earns the premium; frozen pork and offal fill containers for long voyages.

The structural risks are biological and regulatory. Herds are dense and disease moves fast through them, veterinary certification governs which markets are open, and both feed supply and slaughter capacity are concentrated enough that one failure at either end shows up in prices within a week.
