USDA SHRIMP MARKETING SIZES(COUNTS) & FACTOIDS
Shrimp have been the most popular form of seafood consumed in the USA for years.
They represent more than a quarter of the seafood eaten in this country. It's also one
of the most varied categories: You can find dozens of different species of shrimp, each
boasting multiple names and preparations. You can buy them with the head on or off,
the shell on or off, the vein removed or intact, tail-on or tailless. Some are available
pre-cooked; others are frozen, fresh, or previously frozen. Then there's the matter of
shrimp vs. prawns, just to further muddy up the waters (and many species of shrimp,
for what it's worth, prefer muddy waters).Shrimp Come in MANY differing sizes.
Purchasing them out of the back of a pickup truck or on a street corner guarantees you
NOTHING other than perhaps FRESHNESS. Packaged (usually frozen) shrimp labelling
is a different story. The USDA has pre-determined the number (range) of shrimp tails
that MUST be contained in a pound. The Trade Names of each of the sizes are also pre-
determined and cannot vary. Thus: Jumbo Shrimp WILL contain between 21 and 25
HEADLESS shell-on shrimp tails in each pound with the “average” number in each
package being about 23. Purchasing shrimp with their heads still on will give you
SMALLER shrimp tails in each pound. Shells on/off, tail shells only, cooked, raw etc.
WILL result in slight count/size variances.

There are over 3,500 Species of Shrimp. The world consumes 850 million pounds of
Shrimp each year. In U.S.A. waters we have only White, Brown and Pink Shrimp. Most
other “kinds” of Shrimp (Tiger, Chilean Red, Freshwater, etc.) will come from other
countries. ALL Shrimp basically taste the same, the differences are caused by what
they eat. There are a myriad of different Shrimp packages available at your local
Seafood Market and Grocers. In truth, there are only THREE common ways to
purchase Shrimp of all sizes. Within each of these 3 choices are a myriad of additional
choices to be made. Here we attempt to clarify and assist you with correctly making
those choices.
#1) FRESH: Fresh Shrimp are normally available only on our sea coasts. While you
may well not be guaranteed they are USDA inspected, you CAN with a little effort
become your own “inspector”. The Shrimp MUST be stored on a thick layer of FRESH
crushed Ice whether in the box or the display case. The Shrimp should all look to be
roughly the same size. The Shrimp should SMELL fresh (like the Sea) and the Shells
should not be spongy, soft, be heavily pitted or have any black spots. - Ask the
vendor to hand you one of the Shrimp and make certain it is taken off of the pile you
will be purchasing from. Stick it up under your nose and inhale deeply. FRESH,
FRESH, FRESH! If you detect ANY odor, no matter how slight, PASS THEM BY! Press
on the Shell, if it bends easily and stays bent, PASS THEM BY. Paper thin Shells are
perfectly OK since as Shrimp grow, they shed their entire Shell and slowly grow a
new one. As that new Shell grows, it gets thicker - Your Shrimp may have just
recently shed their Shells.
#2) BLOCK FROZEN: Class Restaurants (AND YOU SHOULD TOO) normally purchase
their USDA inspected Shrimp in large frozen blocks (about 10 pounds each - see
picture). Block frozen & sealed Shrimp will last for MONTHS in your sub-zero
temperature freezer. Block freezing GUARANTEES you the best textured and tasting
Shrimp you will ever find. Thawing and refreezing for lesser quantities is easy.
#3) INDIVIDUALLY QUICK FROZEN (IQF): Acceptable if they haven’t been
improperly thawed or kept frozen for too long a period. If the bag has a clear section,
inspect carefully for freezer burning (Milky white areas on the flesh). The majority of
Shrimp away from the sea coasts will always be Individually Quick Frozen. Even the
“unfrozen” Shrimp you see displayed in your grocers seafood case will have most
likely been previously frozen and thawed by your Grocer (properly or improperly is a
question you need to determine for yourself).
CAN THAWED SHRIMP BE RE-FROZEN?
The generic answer is YES - ONCE. Shrimp (and most other Seafoods) are made up of
77% to 88% moisture. Can you freeze, thaw and refreeze water without damage -
ABSOLUTELY. The sticking point is in HOW they were thawed….
1) Slowly thawed from hard frozen in a refrigerator that is below 42 degrees? The
answer is YES, their texture and flavor should not change much at all! This is a one-
time deal - Do NOT EVER thaw & refreeze Shrimp more than ONE TIME!
2) Quick-thawed in water or just sitting out on your warm counter top? The answer
is a resounding NO! Long story short, thawed Shrimp out of your grocers seafood
case - BE SAFE, do NOT refreeze them - Odds are extremely high that he has more
still frozen in the back - ask to get those so you can thaw them properly.
10 POUNDS OF BLOCK FROZEN SHRIMP - REALLY?
Yeah, Yeah, Yeah, I know. What family can eat 10 pounds of thawed Shrimp in a
single day? None of us unless you happen to be the Old Woman Who Lived In A Shoe.
The answer here is to PROPERLY THAW the Shrimp Block! then place the thawed
Shrimp in freezer bags sized as necessary for your family, fill the bags with water so
all of the Shrimp are submerged, stand them upright in the freezer until frozen, seal
and they’ll keep for several months.
PRE-COOKED SHRIMP
Unless it’s an unforeseen catastrophic emergency “OMG I forgot about tonight’s
promised Shrimp Cocktail Appetizer”! Never, Ever, NEVER buy pre-cooked Shrimp to
serve to someone you care for. ALWAYS use Raw Shrimp for your Dishes & Appetizers
and cook them properly.
BAKED, BOILED, BROILED, GRILLED OR STEAMED
Broiling is the preferred method for cooking Shrimp for Appetizers (See: Appetizers -
Perfect Broiled Shrimp Cocktail for those easy details). Boiling Shrimp tends to leach
out most of the flavor into the water that you will be discarding. Broiling Shell on
Shrimp is always great tasting, but a bit difficult since the high temperature of a
broiler can be slightly different from oven to oven along with the rack distances from
that broiler element. Grilling Shell on Shrimp is also great tasting, but very difficult
since the temperature of different grills can be extremely variable. Steaming thawed
Shrimp with the shells still on WILL give you a much better flavored Shrimp than
boiling will, but is very difficult to get ALL of them equally cooked.
COOKING STILL-FROZEN SHRIMP
Seafoods are EXPENSIVE! Loads of people and even a few uninformed Chefs believe
that cooking still-frozen Crab Legs, Lobster Tails, Fish Fillets, Shrimp and other
Shellfish is perfectly OK. The truth here is that since you don’t seem to care much
about the texture and taste of the Seafood you are eating, THEN BUY SOMETHING
LESS EXPENSIVE TO RUIN!. Since Seafoods contain so much moisture, most are
considered to be fully cooked as soon as that moisture reaches the correct internal
temperature (USDA = 145 degrees F), overcooking even slightly past that
temperature causes the texture to begin to turn rubbery. Thick pieces of Seafood,
Lobster Tails, King Crab, Huge Shrimp, etc. will slowly thaw towards the center as you
cook them. Cooking until the center is the correct temperature means that the
outside temperature will end up OVERCOOKED and rubbery! Already thawed Seafood
has the same problem, but to a much lesser degree. If thawed, the warm center
cooks correctly much quicker than if frozen. The outside cooks for less total time and
does not get as tough. DO WHAT YOU MAY!
HEADS-ON VS HEADS-OFF SHRIMP
Shrimp with their heads still on are popular mostly throughout Asia. Most Asians refer
to them in dishes as “Dragons”. Those with the heads already removed are popular in
nearly every culture, giving you the most bang for your buck because the
overwhelming quantity of edible meat is contained within the tail.
1) PROS: Purchasing Raw Shrimp with their heads still on them? GREAT! The intense
flavors contained in the Head will migrate into the tail meat as they cook and you can
suck those wonderfully flavored juices out of the separated heads before peeling and
eating the Tail. If needed, the separated RAW heads and Shells can be used to create
a fantastic flavored Seafood Stock with a myriad of tasty uses!
2)CONS: The USDA “count” per pound contains FAR fewer tails if the heads are still
on them. Discarding those raw heads wastes about 1/3 of that expensive purchase
price.
TO DE-VEIN OR NOT TO DE-VEIN
THE HARD RULE: ALWAYS De-Vein your Shrimp if not already done. The dark
colored Vein is a Shrimps intestinal tract. “WE” have completely succeeded in
poisoning our oceans - The intestinal tract MAY contain large amounts of
contaminants (Mercury, PCB’s and Dioxins). It can also be a breeding ground for
bacteria such as E-Coli. Consuming raw Shrimp (Sushi, etc.) that has NOT been de-
veined can be dangerous!
POND RAISED VS WILD CAUGHT SHRIMP
Shrimp are omnivores, which means that they consume both plants and animals.
Despite their small size, shrimp actually have a large range of food options in their
diet. Their favorite foods are algae and other plant particles, plankton and even small
fish! It’s these foods, along with the sunny, nutrient-enriched waters of the Gulf of
Mexico and South Atlantic Ocean that help shrimp grow naturally and to taste so
delicious! A Shrimp will always taste like what it eats! a SINGLE female Shrimp will
lay between 100,000 and a million eggs making Shrimp an EASILY sustainable and
reliable renewable resource.
1) POND RAISED: Those who farm shrimp in ponds feed them a diet of pelleted
“feed” or “meal” containing a variety of ingredients ranging from fish meal, poultry
meal, soybean meal, krill meal or plant-based meal. Those meals often contain what
are called chemostimulatory and often artificial additives to improve the animals
growth rate and make the feed more attractive and palatable to them. Pond raised
Shrimp are kind of like cage raised Chickens - Kind of bland and tasteless. Its an
industry accepted fact that the sea water contained in the majority of Ponds is
HIGHLY polluted since it isn’t changed very often.
2) WILD CAUGHT: Wild-caught shrimp live in a natural environment surrounded by
other aquatic creatures, so naturally, in the wild, we humans are competing with
other natural omnivores. The natural habitats for our Wild American shrimp are the
Gulf of Mexico and the South Atlantic Ocean. Those relatively small sizes of shrimp
are considered prey to a vast variety of larger sea-feeding species.
TO BRINE OR NOT TO BRINE
THE HARD RULE: Always, Always, ALWAYS Brine your Shrimp without fail. Brining
GREATLY improves the flavor and texture of ALL Shrimp. The Brining process is very
easy and short (25 minutes maximum) for several reasons (See: Appetizers - Perfect
Broiled Shrimp Cocktail for more information): Technically Shrimp are quite small,
Some of the proteins in Shrimp will actually “cook” at room temperature. The Meat
becomes lightly seasoned. It helps to retain internal moisture.
SHRIMP BRINE
2 Cups Cold Water
2 Cups Crushed Ice
¼ Cup Kosher Salt
¼ Cup Granulated Sugar
1 Large Zip Lock Bag
Add all of the ingredients into the bag, seal and shake until the Salt & Sugar
completely dissolve. Add in the properly THAWED cold Shrimp (peeled or not), reseal
and shake. Refrigerate for a maximum of 25 minutes. Drain the Shrimp, rinse off the
Brine and then wrap them in paper towels to keep them from drying out. Cook very
soon in any chosen recipe.
