Is sheep safe to eat?

Sheep meat, also known as lamb or mutton, has been consumed for thousands of years. It is an important source of protein, vitamins, and minerals for many cultures around the world. However, some people may be concerned about the safety or health effects of eating sheep meat. This article will examine whether sheep meat is safe for human consumption by looking at topics like nutrition, foodborne illnesses, antibiotic use, and environmental contaminants.

Is Sheep Meat Nutritious?

Yes, sheep meat is highly nutritious. According to the USDA, a 3 ounce serving of lamb provides:

  • 175 calories
  • 9 grams of fat
  • 25 grams of protein
  • 10% of the Daily Value for iron
  • 15% of the Daily Value for zinc
  • Smaller amounts of B vitamins, selenium, and other minerals

Compared to other red meats, lamb tends to be leaner and contains less saturated fat. Lean cuts come from the leg, arm, and loin. Lamb is considered a good source of high quality complete protein, providing all the essential amino acids needed in the diet.

In addition, sheep meat contains conjugated linoleic acid (CLA). CLA is a polyunsaturated fatty acid that has been linked with positive health effects in animal studies, such as reduced cancer risk and improved blood lipids. Lamb contains higher levels of CLA compared to beef or pork.

Overall, the nutritional profile of lamb makes it a healthy choice as part of a balanced diet. It provides high quality protein, important vitamins and minerals, and beneficial fats like CLA.

Is Sheep Meat Safe to Eat Raw?

Eating raw or undercooked sheep meat is not recommended from a food safety standpoint. Like with other raw meats, raw lamb may contain harmful bacteria that can lead to foodborne illness.

Potential pathogens found in raw sheep meat include:

  • E. coli O157:H7
  • Salmonella
  • Campylobacter
  • Listeria monocytogenes

These bacteria are killed and rendered harmless when lamb is cooked to a safe internal temperature. The USDA recommends cooking lamb steaks, chops, and roasts to a minimum internal temperature of 145°F. Ground lamb should reach an internal temperature of 160°F.

At rare or medium-rare doneness, some pathogens may survive in undercooked meat. People at higher risk for food poisoning, including young children, seniors, and those with compromised immune systems, should avoid eating undercooked lamb.

Pregnant women are also advised to avoid raw or undercooked sheep meat due to the risk of toxoplasmosis infection, which can harm the developing fetus.

In summary, raw sheep meat may carry pathogens that can cause foodborne illnesses. Cooking lamb thoroughly to safe internal temperatures is recommended to kill any bacteria present and reduce food safety risks.

Does Sheep Meat Contain Antibiotic Residues?

Antibiotics are sometimes used in sheep to treat or prevent diseases. This has raised concerns that antibiotic residues could remain in the meat that humans eat. However, sheep raised for meat in the U.S. must follow withdrawal periods to ensure no unsafe levels of antibiotics remain.

The U.S. Food and Drug Administration (FDA) approves antibiotics for use in sheep only after determining dosage levels and withdrawal times needed to ensure drug residues deplete from the animals’ system. For any drug used, there is a mandatory withdrawal period before the sheep can be slaughtered for consumption. This allows residues to fall to safe levels in the meat.

In addition, the USDA’s Food Safety and Inspection Service (FSIS) monitors meat for violative residues at slaughter facilities. Meat found to contain unsafe levels of antibiotics is removed from the food supply.FSIS residue testing shows a very low rate of antibiotic violations in domestically produced sheep meat. Over 90% of samples tested in recent years were compliant with U.S. residue limits.

This testing supports that proper withdrawal periods prevent antibiotic residues in lamb sold for human consumption. Purchasing meat from reputable suppliers provides added assurance the meat does not contain unsafe antibiotic residues.

Are There Environmental Contaminants in Sheep Meat?

Sheep may be exposed to certain environmental contaminants that can accumulate in their meat and organs. Potential contaminants include heavy metals like lead and cadmium, as well as dioxins and polychlorinated biphenyls (PCBs).

However, several factors limit the accumulation of these contaminants in sheep raised for meat:

  • Sheep have a relatively quick turnover from birth to slaughter (12-24 months) compared to cattle, limiting long-term exposure.
  • Sheep raised for meat are typically pasture-raised on open rangelands rather than concentrated feedlots.
  • Regulations restrict emissions and contamination levels in the environment.
  • Testing of sheep meat in the U.S. and Europe consistently shows very low levels of chemical contaminants that are well below safety limits.

Proper management, including testing soil and feed sources, reduces environmental contaminants in sheep production. Buying lamb from reputable local producers can provide added assurance of safe, quality meat.

Does Sheep Meat Cause Creutzfeldt-Jakob Disease?

No, eating lamb and mutton does not pose a risk for Creutzfeldt-Jakob disease (CJD). Some people may still have concerns stemming from the bovine spongiform encephalopathy (BSE) crisis in European cattle during the 1990s. However, Creutzfeldt-Jakob disease has never been associated with sheep meat.

Creutzfeldt-Jakob disease is caused by abnormal prion proteins in the brain, causing sponge-like holes and neural damage over time. The disease has a very long incubation period before symptoms arise.

While BSE did spread through feeding cattle meat-and-bone meal containing prion proteins, sheep were not affected by this practice. Sheep brains and spinal cords, where prions accumulate, have never been included in sheep meat for human consumption. There is no scientific evidence that CJD has spread to humans through eating lamb or mutton.

In some cases, scrapie, a prion disease in sheep, has been detected in flocks. However, scrapie prions have a different cellular mechanism than BSE prions and have not been found to cause disease in humans. Regulations prohibit any sheep known to have scrapie from entering the food supply.

In summary, while prion diseases like scrapie can occasionally affect sheep, there is no risk of humans contracting Creutzfeldt-Jakob disease from eating lamb or mutton products.

Does Sheep Meat Cause Heart Disease or Blood Clots?

There is no direct link between eating sheep meat and increased risk of heart disease or blood clots. Lamb is moderate in saturated fat and can be part of a healthy diet.

Early theories suggested red meat might cause heart disease due to its saturated fat content. However, current research indicates the relationship is more complex. The saturated fat in lamb contains different types, such as stearic acid, that are not associated with raising LDL cholesterol levels.

Lean cuts of lamb like leg and loin are relatively low in total fat and saturated fat compared to lamb ribs, ground lamb, and some cuts of beef. Grass-fed lamb also provides a more favorable ratio of omega-3 to omega-6 fatty acids.

Moderate intake of lean red meat does not appear to increase heart disease or stroke risk for the general population. For example, a large 2019 study found consuming 2-4 servings of red meat per week did not raise cardiovascular disease risk.

There is also no proven link between consuming lamb and increased blood clotting. Some earlier concerns stemmed from vitamin K content, but current evidence does not support issues related to blood coagulation.

As with any food, eat lamb in moderation as part of an overall healthy and balanced diet to prevent heart disease. Limit intake of processed lamb products high in sodium like deli meats. Those with medical conditions like hypercholesterolemia should consult their doctor about recommended red meat intake.

Is Sheep Meat High in Cholesterol?

Sheep meat does contain cholesterol, but not significantly more than other meats. A 3 ounce serving of cooked lamb contains 78 milligrams of cholesterol.

For comparison, the same serving size of cooked beef contains 70-95 mg, pork contains 70-100 mg, and chicken or turkey contains 70-90 mg of cholesterol.

Dietary cholesterol used to be a major concern for increasing blood cholesterol levels. However, research now shows saturated fats have a much bigger impact than dietary cholesterol on serum cholesterol.

While lamb does contain cholesterol, it does not significantly raise blood cholesterol levels for most people when consumed in moderation as part of a healthy diet. Leaner cuts of lamb, with excess fat trimmed, can further reduce cholesterol intake.

Those with medical conditions like hypercholesterolemia or diabetes should consult their doctor about dietary cholesterol recommendations. But for most healthy individuals, lamb can be incorporated as part of a diet low in saturated fat for optimal cholesterol levels.

Does Sheep Meat Contain Added Hormones or Steroids?

No, added hormones or steroids are never used in raising sheep for meat in the United States. Federal law prohibits the use of added hormones at any stage of sheep production.

Unlike poultry and cattle, there are no growth hormones approved for use in sheep in the U.S. This includes natural hormones like estrogen or testosterone, as well as synthetic hormones like zeranol. Any presence of added hormones in sheep meat would be illegal.

Sheep producers follow animal welfare guidelines for responsible care and humane handling. Growth-promoting drugs are not permitted. Lambs may receive antibiotics or antiparasitic medicines for prevention or treatment of illness under veterinary oversight, but proper withdrawal periods are followed before slaughter.

Hormone use cannot increase growth or leanness in lamb products. All sheep meat available to consumers is free of added hormones and steroids. Choosing fresh lamb from reputable local producers can provide added confidence in pure, unadulterated meat.

Is Eating Rare Lamb Dangerous?

Consuming raw or undercooked lamb can increase the risk of foodborne illness, so eating rare lamb is not recommended, especially for young children, the elderly, pregnant women, and those with compromised immune systems.

Lamb can potentially harbor bacteria like E. coli, Salmonella, Campylobacter, and more when raw. These pathogens are killed when lamb reaches an internal temperature of at least 145°F. At rare or medium-rare doneness, bacteria can survive inside the meat.

Eating undercooked ground lamb is particularly risky because any pathogens are mixed throughout the meat rather than remaining on the surface. The USDA recommends cooking ground lamb patties and mixtures to 160°F minimum internal temperature.

If lamb is undercooked or consumed raw, such as in lamb tartare, there is a risk of bacterial contamination leading to food poisoning symptoms. Symptoms may include nausea, vomiting, diarrhea, fever, and cramps lasting one or more days.

Properly cooking lamb to recommended safe internal temperatures kills potential pathogens. While some people may prefer lamb cooked rare for optimal flavor and juiciness, it poses an avoidable food safety risk.

Does Sheep Meat Cause Inflammation?

There is no strong evidence that eating lamb directly increases inflammation in otherwise healthy individuals. Early theories linked red meat to inflammation due to saturated fat and omega-6 content. However, current research does not clearly show moderate lamb consumption independently causes systemic inflammation or exacerbates inflammatory conditions.

In fact, lamb provides anti-inflammatory fats like CLA and omega-3 fatty acids. Grass-fed lamb contains higher levels of these beneficial fats than conventionally raised lamb. The omega-3 content in lamb may contribute anti-inflammatory effects for some.

For those with chronic inflammatory disorders, there are a few concerns to consider regarding sheep meat:

  • Cook lamb properly to avoid foodborne bacteria that may spur inflammation.
  • Choose lean cuts to reduce saturated fat intake.
  • Limit processed lamb products high in sodium.
  • Consult your doctor for specific dietary recommendations to manage medical conditions.

Overall, incorporating fresh lean lamb in moderation as part of a healthy diet does not appear to increase systemic inflammation for most people. Those with inflammatory disorders should take care to cook lamb thoroughly and follow any prescribed dietary restrictions.

Does Sheep Meat Contain Trans Fats?

Natural sheep meat does not contain any trans fats. Trans fats form through a process called hydrogenation, when liquid unsaturated fats are converted to solid saturated fats. This manufacturing process adds trans fats to foods like margarines, snack foods, frozen pizzas, and more.

Since lamb is a whole food animal product, it does not undergo hydrogenation. There is no naturally occurring trans fat content in fresh cuts of lamb.

However, be aware that processed lamb products may contain small amounts of trans fats. This includes breaded lamb patties, frozen pre-cooked lamb dishes, snack foods with lamb, and lamb sausages. Always check nutrition labels and select products free of trans fats where possible.

Choosing fresh lamb cuts rather than highly processed lamb products is the best way to avoid consuming any trans fats. Healthiest options include lamb leg, loin chops, shoulder chops, shanks, and ground lamb.

Does Lamb Contain Toxins?

Fresh lamb does not contain harmful toxins when properly raised, handled, and prepared. Lamb is a nutritious and safe meat choice when good production practices are followed.

Potential toxins of concern include:

  • Prions that can cause Creutzfeldt-Jakob Disease – No evidence these accumulate in lamb muscle meat.
  • Residues of medications like antibiotics or antiparasitics – Must meet withdrawal periods before slaughter.
  • Environmental contaminants like dioxins or heavy metals – Low accumulation and testing ensures safety.
  • Bacterial pathogens like Salmonella or E. coli – Proper cooking kills any bacteria present.
  • Rancidity or spoilage toxins – Stay within safe storage times and avoid eating spoiled lamb.

Buying high quality lamb from reputable producers and taking care to handle, cook, and store it properly limits any toxin risks. Choose lambCuts that looks fresh; avoid those with an off smell or slimy texture. Store lamb for only 1-2 days in the fridge or 6-12 months frozen. Cook to a safe internal temperature before consuming.

With sound production practices and proper handling at home, fresh lamb does not present risks from dangerous toxins or residues. It is one of the most nutritious and delicious meat options available.

Is Sheep Meat Ethically Produced?

There are legitimate concerns around the ethical production of lamb and mutton. Sheep raised for meat should be treated humanely and provided proper living conditions throughout their lives.

Seeking out ethically sourced sheep meat involves considering:

  • Animal welfare – Sheep should be able to exhibit natural behaviors and be free of distress, with adequate housing, gentle handling, and protection from disease and predators.
  • Use of antibiotics and hormones – Sheep should receive medications only for health, not solely growth promotion. Withdrawal periods before slaughter must be followed.
  • Transport and slaughter – Stress from transport, crowding, and handling should be minimized. Slaughter must follow humane protocols.
  • Environmental impact – Manure, grazing, and processing impacts should be responsibly managed for sustainability.
  • Working conditions – Farm workers must receive fair wages and work in safe conditions.

When sourcing lamb, look for reputable producers adhering to animal welfare standards. Small, local farms offer more transparency and connection to providers. Pasture-raised lamb offers a more natural and ethical alternative to concentrated feedlot production.

Is Sheep Meat Sustainably Produced?

There are benefits as well as concerns around the sustainability of lamb and sheep meat production:


  • Sheep’s grazing provides an efficient use of grasslands and pastures.
  • Sheep work well in mixed crop-livestock systems by grazing crop residues.
  • Sheep require less water, crops, and medications than cattle.
  • Sheep manure provides organic fertilizer.


  • Overgrazing can degrade grasslands and cause erosion.
  • Raising sheep for meat consumes resources and emits greenhouse gasses.
  • Improper management of manure runoff can pollute waterways.

Overall, well-managed sheep production can offer environmental advantages over other meat industries. Buying locally raised lamb, compliant with grazing regulations, supports smaller-scale sustainable practices.

Transitioning toward more plant-based diets may also reduce demand for sheep meat and associated impacts. But targeted reductions in other meat sectors likely pose greater sustainability gains.


Sheep meat offers nutritional benefits as a lean, protein-rich food. When properly sourced and prepared, lamb poses minimal health or safety risks. There are legitimate ethical and environmental concerns around all meat production. However, sheep raised humanely on well-managed pastures are a quality choice. Choosing locally produced lamb supports transparency and sustainability. For those who include red meat in their diet, lamb and mutton from trustworthy sources remain healthy and flavorful options in moderation.
