Home Canning of Meat and Poultry
Prepared by CONSUMER AND FOOD ECONOMICS INSTITUTE Agricultural Research Service
Fresh, wholesome meats and fresh, wholesome poultry are suitable for home canning. Frozen meats also may be canned at home.
Popular meats for home canning are—
—Beef, veal, mutton, lamb, pork.
—Chicken, duck, goose, guinea, squab, turkey.
—Rabbit.
—Game birds.
—Small-game animals.
—Large-game animals.
Meat and poultry canned at home must be processed in a pressure canner. Either glass jars or tin cans may be used for home canning.
To insure the safety and wholesomeness of the meats you can at home—
—Start with good-quality fresh or frozen meat.
—Keep all meat, work surfaces, and equipment clean.
—Make sure the pressure canner is in good working condition.
—Pack and close containers carefully.
—Process meat for recommended time.
—Test seals after cooling containers.
—Label containers.
—Store canned meat in cool, dry place.
Acknowledgment is made to the research laboratories of the National Canners Association for consultation and advice on processing.
Follow all canning directions carefully. Processing times and temperatures were developed specifically for use with a pressure canner.
Meat may contain bacteria that cause botulism, a severe form of food poisoning. These bacteria are destroyed when cans or jars of food are processed at a temperature of 240° F. for the times specified.
There is a risk of botulism from home-canned meats if the processing temperature is lower than 240° F. or if processing time is shorter than recommended.
It is not safe to process canned meat in a boiling-water bath, an oven, a steamer without pressure, or an open kettle. None of these methods will heat the meat enough to kill dangerous bacteria in a reasonable time.
There also is a risk of botulism if shortcuts are taken in canning meats, if untested directions are used, or if processing times (pp. 18 to 23) are changed.
Getting Ready
Meats
Use only good-quality meat or poultry—home-produced or purchased from a farm or store.
Chill home-produced meat immediately after slaughter to prevent spoiling and to permit tenderizing. Meat is easier to handle when it is cold. For thorough chilling, keep meat at a temperature below 40° F. until time to prepare it for canning; can it within a few days after slaughter.
If refrigeration is not available and if the maximum daily temperature is above 40° F., process the meat as soon as body heat is gone.
If meat must be held for longer than a few days, freeze it. Store frozen meat at temperatures of 0° F. or lower until canning time. Then cut or saw frozen meat into pieces of desired size.
If frozen meat is thawed before canning, thaw it in a refrigerator at a temperature of 40° F. or lower until most of the ice crystals have disappeared.
Keep all meat clean and sanitary. Rinse poultry thoroughly in cold water, then drain.
Keep all meat as cool as possible during preparation for canning. Handle it rapidly; process it as soon as containers are packed.
Equipment
To control the bacteria that cause spoilage, keep everything that touches meat as clean as possible.
Scrub metal, enamelware, and porcelain pans in hot soapy water. Rinse pans well in boiling water before putting meat in them. Wash knives and kitchen tools to be used in canning; rinse well with boiling water.
Cutting boards, wood utensils, and wooden work surfaces need special treatment to keep spoilage bacteria under control. Scrape surfaces if necessary; scrub with hot soapy water and rinse well with boiling water. Then disinfect clean surfaces.
For disinfecting, use a liquid chlorine disinfectant (household laundry bleach) or other disinfectant. Dilute according to directions on the container. Cover wooden surfaces with the disinfectant solution and leave 15 minutes. Wash solution off with boiling water.
Pressure canner
To insure the safety of canned meats and poultry, jars or cans must be processed at a sufficiently high temperature for a long enough time to kill all bacteria that cause spoilage or food poisoning.
The only practical way to get this high temperature is to use a pressure canner. When steam is held under 10 pounds of pressure at sea level, the temperature in the canner quickly reaches 240° F.—the necessary safe temperature for canning meat.
A pressure canner should be equipped with a rack to hold jars or cans.
A pressure saucepan with accurate controls may be safely used for processing meats in pint jars or No. 2 cans. If you use a pressure saucepan, add 20 minutes to the processing times specified.
Before using the canner, wash the kettle well. Do not put cover with dial gage in water. Wipe the cover carefully with a hot soapy cloth; repeat with a clean damp cloth. Dry. Keep the petcock and safety valve clear. Before each use of the canner, inspect these openings. To clean, draw a string or narrow strip of cloth through the petcock.
_Pressure adjustments._—If you live above sea level, you may need to adjust steam pressure in your canner to get a temperature of 240° F. The rule: For each 2,000 feet above sea level, increase the pressure by 1 pound.
Caution: Do not increase processing time when you increase steam pressure.
If a weighted gage is used at a high altitude, have it corrected for altitude by the manufacturer of the canner.
_Gage adjustments._—When a weighted gage is adjusted for altitude, it needs no further regulation.
A dial gage should be checked before the canning season. If you use the canner frequently, have the gage checked several times a year. Ask your extension home economist, your dealer, or the manufacturer about checking the accuracy of a dial gage.
If the dial gage is not accurate, tie a warning tag to the canner. On the tag, write the margin of error, the date the canner was tested, and the gage setting to use for the correct pressure (see below).
All directions in this bulletin require processing at 10 pounds of steam pressure. The following adjustments give the correct pressure:
If the gage reads high—
1 pound high—process at 11 pounds. 2 pounds high—process at 12 pounds. 3 pounds high—process at 13 pounds. 4 pounds high—process at 14 pounds.
If the gage reads low—
1 pound low—process at 9 pounds. 2 pounds low—process at 8 pounds. 3 pounds low—process at 7 pounds. 4 pounds low—process at 6 pounds.
It is not safe to use a canner if the dial gage registers as much as 5 pounds high or low. Replace a faulty gage with an accurate one.
Glass jars
Jars may be widemouth or regular type. Pints and quarts are satisfactory sizes for canning meats and poultry.
There are two types of jar closures:
—Flat metal lid with sealing compound and a metal screw band. This closure seals as jar cools.
—Porcelain-lined zinc cap with a shoulder rubber ring. This cap must be tightened to complete the seal immediately after meat is canned.
Be sure all jars and closures are perfect. Discard jars with cracks or chips; discard lids and bands with dents or rust. Defects prevent air-tight seals.
Metal screw band Metal lid with sealing compound Seals here Porcelain lined screw cap Rubber Seals here
Before canning, jars must be thoroughly clean. It is not necessary to sterilize them before they are filled, however. Processing at the recommended steam pressure sterilizes both the containers and their contents.
Wash jars and lids in hot soapy water; rinse well. Some metal lids with sealing compound may need boiling or holding in boiling water for a few minutes before use. Do not reuse metal lids with sealing compounds. Follow the manufacturer’s directions.
If you use rubber rings, get new ones of the right size to fit jars. Don’t test by stretching. Wash rings in hot soapy water. Rinse well.
Tin cans
Use plain tin cans in good condition for canning meats.
C-enamel, R-enamel, and sanitary-enamel cans are not suitable for meat. Fat in meat or poultry may cause enamel to peel off the inside of the can. Meat in such cans appears unappetizing, but it is not harmful.
Make sure that cans, lids, and gaskets are perfect. Discard cans that are badly bent, dented, or rusty; discard lids with damaged gaskets.
Protect lids from dirt and moisture by storing them in original packing.
Directions are given for canning meat in No. 2 and No. 2½ tin cans. A No. 2 can holds 2½ cups; a No. 2½ can holds 3½ cups.
Wash cans in clean hot water just before use. Drain upside down.
Do not wash lids of cans, because washing may damage the gaskets. If lids have become soiled, rinse with clean water or wipe with a damp cloth when you are ready to put them on cans.
Sealer
If you use cans, you need a sealer in good working order. Before processing meat or poultry, adjust sealer according to manufacturer’s directions.
The finished seam between lid and can should be smooth and even.
Test by sealing a can containing a small amount of water. Submerge the sealed can in boiling water for a few seconds. If air bubbles rise from around the can, the seam is not tight. Readjust the sealer.
Thermometer
It is a good idea to use a thermometer both when meat is packed hot and when the canning directions call for removing (exhausting) air from jars or cans. With a thermometer, you are able to make sure meat is heated to 170° F.—the minimum temperature needed to exhaust air properly.
Place thermometer in center of jar or can that is being heated. The thermometer bulb should be about half-way to the bottom of the container.
If a thermometer is not available, follow the times given in the directions.
Canning Methods
Prepare and process meat and poultry according to general directions given. Directions specify the types of packs and types of containers suitable for each meat product listed. Instructions must be followed carefully to assure a product safe from spoilage.
Detailed directions for canning meats are given on pages 18 to 20. Picture sequences are shown on pages 14 and 15.
Detailed directions for canning poultry are given on pages 21 to 23. Pictures illustrating main steps are on pages 16 and 17.
How To Make Broth
To make meat or poultry broth, place bony pieces in saucepan and cover with cold water. Simmer until meat is tender. Pour broth into another pan; skim off fat. Add boiling broth to containers packed with precooked meat or poultry; fill to level specified in directions.
Packing
Pack meat loosely in containers. Jars may lose liquid during processing if they are packed too tightly or too full.
Work with one glass jar or tin can at a time. Keep precooked meat hot while packing. Use boiling liquid—broth, meat juice, or water—if directions call for added liquid.
Two methods are used for packing meat:
• _Hot pack._ Meat is precooked before it is packed in jars or cans. Boiling broth or boiling water is poured over meat before containers are processed in a pressure canner. (See p. 8 for directions on how to make broth.) The temperature of food packed hot should be at least 170° F. at the time jars are closed or cans are sealed.
• _Raw pack._ Meat is packed uncooked. Raw-packed meat usually is heated to 170° F. to exhaust—or remove—air from jars or cans before processing in a pressure canner.
Directions for canning in glass jars require exhausting air from raw-packed meat products, except meat-vegetable stew and raw pack poultry, with bone. These two products may be processed without exhausting if they are raw packed in glass jars according to directions on pages 20 and 22.
Directions for using tin cans include exhausting air from all raw-packed meat. It always is necessary to exhaust air from raw-packed meat in tin cans before processing because air has no way to escape after cans are sealed.
Exhausting air
To exhaust—or remove—air, set open jars or cans packed with raw meat on a rack in a large pan of boiling water. Water level should be about 2 inches below tops of jars or cans. Cover the pan. Cook meat in containers at slow boil until temperature at center of jars or cans registers 170° F. If a thermometer is not available, follow times given to cook meat until medium done.
When raw-packed meat is heated to 170° F., air is driven out of the food so that a vacuum will be formed in jars or cans after processing and cooling. Exhausting air also helps to prevent changes in the flavor of canned meat.
Salt
Salt may be added to canned meat for flavor. It does not act as a preservative in canned meat, so it is not needed to make the product safe.
If you decide to use salt, add it after meat is packed in the jar or can. Amounts for various sized containers are given in the canning directions.
Fat
Remove as much fat as possible from meat before canning. Cut off all large lumps; trim marbled meat without slashing the lean unnecessarily.
Do not use excessively fat meat or poultry for canning.
After packing containers, wipe the tops free of fat. Any fat that gets on the rim of jars or cans may prevent an airtight seal.
Closing Jars
If jar has a flat metal lid: Wipe rim of packed jar to remove fat and meat particles that might prevent a proper seal. Put lid on jar with sealing compound next to glass. Screw the metal hand down tight by hand. When band is screwed tight, this lid has enough “give” to let air escape during processing. Do not tighten band further after taking jar from canner.
If jar has a porcelain-lined zinc lid: Fit wet rubber ring down on shoulder of empty jar. Don’t stretch ring unnecessarily. Pack jar with meat. Wipe rubber ring and jar rim clean. Then screw cap down firmly and turn it back ¼ inch before processing. As soon as you take jar from canner, screw cap down tight to complete seal.
Sealing Cans
Use a can sealer in good working condition. Follow the manufacturer’s directions carefully.
Wipe rim clean; place lid on can. Seal at once.
Processing
Use a pressure canner for processing meat. A pressure saucepan may be used for pint jars or No. 2 cans (see p. 5).
Follow the manufacturer’s directions carefully. Here are a few suggestions about using a pressure canner:
• Put 2 or 3 inches of water in the canner; heat to boiling. Use enough water to prevent the canner from boiling dry.
• Set packed jars or cans on rack in the canner. Allow space for steam to flow around each container. If there are two layers of cans or jars, stagger the top layer. Use a rack between layers of jars.
• Fasten canner cover securely so that all steam escapes through the petcock or weighted-gage opening.
• Let steam pour steadily from vent for 10 minutes to drive all air from the canner. Then close petcock or put on weighted gage.
• Let pressure rise to 10 pounds (240° F.). The moment this pressure is reached, start to count processing time. Regulate heat under the canner to maintain even pressure. Do not lower pressure by opening petcock. Keep drafts from blowing on canner. Fluctuating pressure during processing causes liquid to be drawn out of glass jars.
• Watch processing time carefully. When time is up, remove canner from heat immediately.
• If meat is packed in jars, let canner stand until pressure drops to zero. Do not pour cold water over canner. When pressure is reduced suddenly, jars lose liquid. After pressure registers zero, wait a minute or two. Then slowly open petcock or take off weighted gage. Unfasten cover and tilt the far side up so steam escapes away from you. Take jars from the canner.
• If meat is packed in cans, remove canner from heat as soon as processing time is up. Open petcock or take off weighted gage at once to release steam. Then unfasten cover, tilting far side up so steam escapes away from your face. Remove cans.
Yield of Canned Meat From Fresh
The number of jars or cans you get from a given amount of raw meat varies with the size of the pieces and the way the meat is packed.
For a 1-quart jar, allow approximately the following amounts of fresh, untrimmed meat with bone or ready-to-cook chicken:
Beef: _Pounds_ Round 3 to 3½. Rump 5 to 5½. Pork loin 5 to 5½. Chicken: Canned with bone 3½ to 4¼. Canned without bone 5½ to 6¼.
After-Canning Jobs
Cooling
Glass jars
As soon as you take jars out of the canner, complete seals if necessary.
Cool jars top side up. Put them on a rack or folded cloth to cool. Keep them away from drafts. Don’t cover.
When jars are cool, take off screw bands. Do not force bands that stick: loosen by covering them with a hot damp cloth. Wash hands and store them in a dry place.
Tin cans
As soon as you take cans out of the canner, put them in cold water. Change water frequently for fast cooling. Remove cans from water while they are still warm so they will dry in the air. If you stack cans, stagger them to allow air circulation.
Checking Seals
Check containers for leaks when jars or cans are thoroughly cool.
Occasionally, a can packed too full bulges at the ends. Set it aside and use within a few days. This will prevent later confusion with cans that bulge from spoilage during storage.
On the day after canning, examine each jar carefully. Turn it partially over. If jar has a flat metal lid, test seal by tapping center of lid with a spoon. A clear ring means a good seal. A dull note, however, does not always mean a poor seal. Another test is to press on the center of the lid; jar is sealed if lid is down and does not move.
Examine seams and seals carefully on all cans. Can ends should be almost flat, with a slight inward curve. Buckled or broken seams may be caused by cooling cans too fast or by not filling cans with enough meat.
Do not store leaky jars and cans. Either use the food at once or can it again in another container. Begin the second canning by heating meat through. Then pack and process it in a pressure canner for the full time recommended.
Do not open and refill jars that have lost liquid during processing. Loss of liquid does not cause canned meat to spoil. Opening would contaminate the sterile contents, and meat would have to be processed again to insure safety.
Labeling
Wipe containers after they are cool. Label each jar and can to show contents and date of canning. If you canned more than one lot on one day, add a lot number.
Storing
Select a cool, dry place for storing canned meat and poultry. Protect meat from heat, from freezing, and from dampness.
Heat causes canned foods to lose quality. Do not store canned meats in direct sunlight, near hot pipes, or near heat.
Freezing does not cause canned meat to spoil, but it may damage the seal so that spoilage begins. In an unheated storage area, cover jars and cans with a clean, old blanket or wrap them in newspapers.
Dampness may corrode cans or metal jar lids and cause leakage.
Spoilage
Immediately destroy any canned meat that has spoiled. Burn it or dispose of it where it cannot be eaten by humans or animals.
Do not taste canned meat that you suspect of being spoiled.
Take these positive steps to insure the safety of canned meat—
—Keep meat and equipment clean.
—Follow recommended methods, including processing times and temperatures.
—Cool and store properly.
To avoid any risk of botulism—a serious food poisoning—it is essential that the pressure canner be in perfect order and that every canning recommendation be followed exactly. Unless you are absolutely sure of your gage and canning methods, boil home-canned meat 20 minutes in a covered pan before tasting or using.
Boiling is the best way to find out if canned meat is safe. Heat brings out the characteristic odor of spoiled meat. If meat develops such an odor, destroy it without tasting.
If boiled meat is not to be used at once, or if it is to be used in salads or sandwiches, refrigerate it immediately.
Be alert to signs of spoilage when you take meat containers from storage. Bulging jar lids or rings, gas bubbles, leaks, bulging can ends—these may mean the seal has broken and the food has spoiled. Test each can by pressing the ends; ends should not bulge or snap back.
Check the contents as you open the container. Spurting liquid, off-odor, and color changes in meats are danger signals.
Sulfur in meat often causes metal lids or cans to darken. This discoloration does not affect the safety of the meat.
