One of our most enduring American images is that of the great American buffalo, or species
Bison bison. These huge, shaggy animals once roamed from Canada to Mexico, grazing
the Great Plains and mountain areas of our country. Bison were the center of life for the
Plains tribes of Native Americans who found in them nearly all the food, clothing, and
shelter they needed. Hunted for their furs in the 1600's and later for their tongues, bones,
and meat, it was estimated by 1893 that there were only slightly more than 300 bison left,
from numbers estimated at one time to be over 60 million. The following information is about
this species which is making a comeback and growing rapidly in numbers.

What is bison?
The National Bison Association encourages the name bison to differentiate the American
buffalo from the Asian Water buffalo and African Cape buffalo. The American buffalo is
not a true buffalo. Its scientific name is bison and it belongs to the bovine family
along with domestic cattle. The bison bull is the largest animal indigenous to North America.
A bull can stand taller than 6 feet at the hump and weigh more than a ton. They are strong
and aggressive, and can jump as well as deer, outmaneuver horses, and break through fences
that would imprison other livestock.
"Beefalo" are 3/8 bison and 5/8 domestic cattle. (The natural result of a
bison–domestic bovine cross breeding is a sterile offspring. It has taken years of
research to develop this breed.) The advantages of this cross are fertility and easy calving.
Beefalo gain weight well on inexpensive, high-roughage feed and are very hardy.

How are bison raised?
According to the most recent Census of Agriculture (in 2007), there were approximately 200,000 bison
in the U.S., more than 25% of them in North and South Dakota. Unlike the
older, tougher animals the Native Americans ate, today's bison are custom-fed and slaughtered
at about 18 months, so the meat is as tender as beef. Some 20,000 buffalo are slaughtered each
year (compared to approximately 125,000 cattle per day).
Bison are allowed to roam freely most of their lives. They are raised on the open range and
eat hay or grass. They are usually given grain during the last 90 to 120 days before slaughter.
(The fat of grass-fed animals is yellow, which is good since it contains beta-carotene;
however, most consumers prefer the fat to be white.) Surplus buffalo bulls are selected at
about 2 1/2 years of age (buffalo can live to be 40 years old) and spend a very short time
in the feedlots.

Can hormones and antibiotics be used in bison raising?
Antibiotics and growth hormones are not given to bison.

How is bison inspected?
Bison may be inspected under voluntary federal inspection or FDA equivalent inspection. FDA equivalent inspection
includes state inspection. Under voluntary federal inspection by USDA's Food Safety and Inspection Service (FSIS),
businesses pay an hourly rate for inspection services. Voluntary inspection is handled under the Agriculture Marketing Act,
which gives the Secretary of Agriculture the authority to take whatever steps are necessary to make the product marketable.
Federal inspection is done on a carcass-by-carcass basis by FSIS. The FSIS inspector must have knowledge about that
particular species and the carcass must fit available equipment in the plant. Each bison and its internal organs are
inspected for signs of disease. The triangle shaped "U.S. Inspected and Passed" seal ensures the bison is wholesome and
free from disease. Note: Some states require all exotic animals be inspected in order to be sold in commerce.

Is bison graded?
No.

How is bison different from beef?
Bison is a deeper red color before cooking because there is no marbling (white flecks of fat within the meat muscle).
Bison is said to have a sweeter, richer flavor than beef and has less fat and fewer calories than beef.
According to USDA's Agricultural Research Service (ARS),100 grams of raw bison (separable lean only) contains 109
calories and 1.8 grams fat. The same amount of raw beef (separable lean only, Choice grade) contains 291 calories, and
24 grams fat.

How much bison is consumed?
The National Bison Association estimates annual U.S. per capita consumption at .07 pounds per person.

Safe Handling of Bison
Handle bison meat the same as any other type of meat. Make your selection just before
checking out at the register. Put packages of raw bison in disposable plastic bags
(if available) to contain any leakage which could cross contaminate cooked foods or produce.
Take packaged bison home immediately and refrigerate it at 40 °F or below; use within 3 to 5 days,
or freeze at 0 °F or below. If kept frozen continuously, it will be safe indefinitely.

Thawing Frozen Bison Meat
There are three ways to thaw meat: in the refrigerator, in cold water, and in the microwave.
Never thaw on the counter or in other locations. It's best to plan ahead for slow, safe
thawing in the refrigerator. To thaw in cold water, do not remove packaging. Be sure the
package is airtight or put it into a leakproof bag. Submerge the package in cold water,
changing the water every 30 minutes so it continues to thaw.
When microwave defrosting meat, plan to cook it immediately after thawing because some areas of
the food may become warm and begin to cook during microwaving. Holding partially cooked food is
not recommended because any bacteria present wouldn't have been destroyed.
Foods defrosted in the microwave or by the cold water method should be cooked before refreezing
because they may potentially have been held at temperatures above 40 °F allowing harmful
bacteria to grow.

Preparing Bison
Bison is very lean and lacks fat marbling, so care should be taken to not overcook it.
- In general, bison should be cooked using low heat (325 °F) and longer cooking times.
- Braising or other moist cooking methods are recommended for bison roasts and steaks.
- For thin-sliced bison, use quick cooking methods such as broiling and pan frying.
- Cook raw ground bison to an internal temperature of 160 °F as measured with a food thermometer.
- Cook all raw bison steaks and roasts to a minimum internal temperature of 145 °F as measured with a
food thermometer before removing meat from the heat source. For safety and quality, allow meat to rest for
at least three minutes before carving or consuming. For reasons of personal preference, consumers may choose
to cook meat to higher temperatures.
- Less tender cuts should be braised (roasted or simmered with a small amount of liquid in a tightly covered pan) or stewed.

Storage Times
Purchase bison products before any "Sell-By" dates expire. It is not important if a date expires after
freezing bison because all foods stay safe while frozen. Because purchase dates are a guide to the retailer, follow
these tips for safe storage and use at home.
- Follow handling recommendations on product.
- Keep bison meat in its package until using.
- It is safe to freeze bison meat in its original packaging. If freezing longer than 2 months, overwrap these packages with airtight heavy-duty foil, plastic wrap or freezer paper, or place the package inside a plastic bag.
- For best quality, cook or freeze ground bison or stew meat within 2 days of purchase; larger cuts such as roasts and steaks, within 3 to 5 days.
- Ground or cut-up bison meat will keep its best quality in the freezer for 4 months. Larger cuts, such as chops, steaks, legs, or loins will keep their best quality 6 to 9 months.
- After cooking, eat or freeze bison within 3 to 4 days.
