It is widely known that people love pets, especially domestic cats, which have become a popular presence in many households. Both adults and children enjoy raising and taking care of them. As discussions about the benefits of having cats in the home have increased, including the joy and happiness they bring, many people have become more inclined to adopt cats, even in homes with pregnant women. However, this comes with some health warnings from doctors.
One of the most significant concerns is toxoplasmosis, commonly referred to as "cat disease." This is a parasitic infection that can pose risks to pregnant women and their unborn babies. While the cat itself is often cited as the primary source of this disease, there are actually other surprising ways in which a pregnant woman can be exposed to the parasite. Dr. Noha Dawood, a clinical nutrition expert, shares insights on the sources of toxoplasmosis and provides tips for preventing the disease and protecting both the mother and fetus.
What is Toxoplasmosis?
Toxoplasmosis, or "cat disease," is caused by a parasite called Toxoplasma gondii. This infection can be transmitted to a pregnant woman if she comes into contact with infected cat feces, which may contain parasite eggs. The infection is usually not dangerous for healthy individuals with a strong immune system, as their body can control the parasite without showing symptoms. However, for pregnant women, whose immune systems are weaker, the parasite can pose significant risks to both the mother and the baby, including:
- Miscarriage
- Premature birth
- Congenital defects in the baby, such as blindness, mental disabilities, an abnormally small head, seizures, calcifications in the brain, low birth weight, jaundice, and neonatal fever.
Additionally, a breastfeeding mother infected with the parasite may transmit it to her baby through her breast milk.
Sources of Toxoplasmosis Infection for Pregnant Women
-
Processed Meats and Burgers Pregnant women should avoid consuming processed meats, such as those found in fast food, as they often use meat from unknown sources. These meats, including animal offal and chicken legs, may be contaminated with the toxoplasma parasite. It's crucial to ensure that meat is thoroughly cooked, as the parasite can survive in undercooked meat. For example, burgers may be grilled only on the outer surface, leaving the inside undercooked, which does not kill the parasite.
-
Contaminated Drinking Water Ensure that the water you drink comes from a clean and safe source. Pregnant women should avoid drinking water from untrusted sources, including some restaurants and cafes, where the staff may not maintain proper hygiene after using public restrooms. Carry your own water bottle to ensure that it is clean and safe for consumption. Drinking at least eight glasses of water a day is essential for hydration during pregnancy.
-
Unwashed Fruits and Vegetables Fruits and vegetables that are not properly washed under running water can be contaminated with the toxoplasma parasite. Cats sometimes defecate near plants, and fruits and vegetables can be exposed to both cat feces and human waste, which may contain the parasite. Since the immune system of pregnant women is weaker, they are at higher risk of contracting the infection, even if the parasite doesn’t show symptoms in healthy individuals.
-
Unboiled Fresh Milk Fresh milk should be boiled thoroughly before consumption. Although milk is an important source of calcium and vitamin D, consuming unboiled milk can expose pregnant women to the toxoplasma parasite. If you prefer not to drink hot milk, make sure to boil it for at least 10 minutes to kill any harmful bacteria or parasites. Drinking milk at the proper temperature ensures that it is safe for consumption.
Symptoms of Toxoplasmosis in Pregnant Women
If a pregnant woman contracts the toxoplasma parasite, the symptoms typically appear about three weeks after exposure. The infection can be detected through blood tests, which will show antibodies against the parasite. The timing of the infection can be determined based on the types of antibodies present in the test results. It is important to seek medical attention if you suspect an infection, whether from a household cat or other sources. In some cases, the doctor may examine an amniotic fluid sample surrounding the baby to diagnose the infection.
While the infection in the early stages of pregnancy may not pose a severe risk to the baby, it is still important to seek medical advice. If toxoplasmosis is detected, the mother may be treated with antibiotics to reduce the risk of complications.
In conclusion, although cats can be a source of toxoplasmosis, there are several other ways the infection can spread. By following proper hygiene practices, ensuring the safety of food and water, and taking extra precautions, pregnant women can minimize the risks to themselves and their babies. Always consult your doctor if you suspect an infection to ensure the health and safety of both mother and child.
