Pregnant women who come into close contact with sheep during lambing, or other farm animals that are giving birth, may put themselves and their unborn child at risk of contracting an infectious disease sometimes carried by these pregnant farm animals. Some of these diseases can cause an abortion in people.
Raw or undercooked meat should be avoided during pregnancy due to the risk of toxoplasmosis, an infection with bacteria often found in raw meat, as well as sheep, lamb and cat feces. Toxoplasmosis is an infection by the Toxoplasma gondii parasite, one of the world's most common parasites.
How can I prevent pregnancy toxaemia? Good nutrition and careful management are the keys to avoiding pregnancy toxaemia. Lambing ewes require feed on offer of more than 1500 kilograms per hectare during lambing. If this is not available, provide a supplementary source of energy, such as good quality hay and grain.
We do not recommend that pregnant women take part in the trek, due to the uneven terrain and the possibility of being kicked by an alpaca.
Handling most animals is fine when you're pregnant – so need to quarantine the family pet! You just need to take a few precautions to avoid infection from cats, sheep and pigs.
Certain uterine conditions or weak cervical tissues (incompetent cervix) might increase the risk of miscarriage. Smoking, alcohol and illicit drugs. Women who smoke during pregnancy have a greater risk of miscarriage than do nonsmokers. Heavy alcohol use and illicit drug use also increase the risk of miscarriage.
Routes of infection include contamination of cuts and grazes by soil, cat litter or faeces in which the parasite is present, and ingestion of tissue cysts in infected meat. Consequently, women should ensure that, if they eat meat during pregnancy, it is well cooked.
Toxoplasmosis and enzootic abortion (EAE) are the two most common causes of sheep abortion that are diagnosed from post-mortem submissions by the Animal Plant and Health Agency (APHA) (Figure 1). Sheep abortion results in considerable economic loss to the flock and increases stress during lambing.
There are no practical medications that can cure sheep infected with toxoplasma or prevent the consequences once an animal has become infected. Following infection, sheep develop immunity to the parasite, which will protect them against disease in a subsequent pregnancy.
In order to protect their own health and that of their unborn child, women who are, or who may be, pregnant should be advised to avoid close contact with livestock animals. This is because infectious organisms may be present in birth fluids of animals, particularly sheep, cattle and goats.
How common is toxoplasmosis during pregnancy? The chances of getting toxoplasmosis for the first time during pregnancy are thought to be very small. Even if you do become infected for the first time during pregnancy, this doesn't necessarily mean your baby is in danger.
But the earlier in pregnancy you get infected, the more serious the baby's problems may be after birth. For example, your baby could have damage to the liver, brain and eyes. Up to 1 in 2 babies (50 percent) who are infected with toxoplasmosis during the pregnancy are born early (preterm). Some infected babies may die.
How are ewes infected? Toxo is “not” spread from sheep-to-sheep. Young cats spread it to sheep.
Clinical Findings of Toxoplasmosis in Animals
The corresponding clinical signs include fever, diarrhea, cough, dyspnea, icterus, seizures, and death. T gondii is also an important cause of abortion and stillbirth in sheep, goats, cervids, and sometimes pigs.
The Toxoplasma parasite does not become infectious until 1 to 5 days after it is shed in a cat's feces. Wash hands with soap and water after cleaning out a cat's litter box. Teach children the importance of washing hands to prevent infection.
Abortions in ewes are the result of many factors that stress the pregnant animal. Intrauterine infections are the most common cause. The commonly reported abortion rate in the New Zealand sheep flock is between one and two per cent, although in 'abortion storms' a single flock can abort 25-40%.
“The number of reports of these infections and human miscarriages resulting from contact with sheep is extremely small. However, it is important that pregnant women are aware of the potential risks associated with close contact with sheep during lambing.”
Lambs and sheep can carry an organism that is known to cause miscarriage in ewes. They also carry toxoplasma. Avoid lambing or milking ewes, as well all contact with newborn lambs.
Pregnant women who come into close contact with sheep during lambing or other farm animals that are giving birth may risk their own health, and that of their unborn child, from infections that such animals can carry.
Toxoplasmosis is caused by the protozoan parasite Toxoplasma gondii. In the United States it is estimated that 11% of the population 6 years and older have been infected with Toxoplasma. In various places throughout the world, it has been shown that more than 60% of some populations have been infected with Toxoplasma.
Your nausea and vomiting may be worse than ever: Morning sickness peaks around 9 or 10 weeks of pregnancy for many women. That's when levels of the pregnancy hormone human chorionic gonadotropin (hCG) are highest (morning sickness is thought to be linked to rises in hCG and estrogen).
Most miscarriages - 8 out of 10 (80 percent) - happen in the first trimester before the 12th week of pregnancy. Miscarriage in the second trimester (between 13 and 19 weeks) happens in 1 to 5 in 100 (1 to 5 percent) pregnancies. Pregnancy loss that happens after 20 weeks is called stillbirth.
Do not eat raw or undercooked meat, chicken, or fish (such as sushi or raw oysters). Do not eat raw eggs or foods that contain raw eggs, such as Caesar dressing. Do not eat raw sprouts, especially alfalfa sprouts. Do not eat soft cheeses and unpasteurized dairy foods, such as Brie, feta, or blue cheese.
