פירות ים והסיכון להריון

החשש באכילת פירות ים הוא מהדבקה בחיידק בשם ליסטריה, שגורם מחלה בשם ליסטריוזיס. עקב השפעת השינויים ההורמונלים על מערכת החיסון נמצא כי סיכויי ההדבקה אצל נשים בהריון גבוהות פי 20!! העובר עלול להידבק בחיידק גם אם האם לא הראתה כל סימני מחלה. הדבר עלול להוביל להפלות, מות העובר, לידות מוקדמות ופגיעה קשה בעובר. בהתאם, אסור לאכול פירות ים (ולשומרי הכשרות שביננו דגים בכלל) לא מבושלים (כמו סלמון מעושן), כי אם רק כאלה שהוצאו מקופסאת שימורים או בושלו היטב! כמובן שיש סכנה נוספת באכילת דגים עקב מתכות כבדות כמו כספית שנאגרות בתוכם, אבל זה לא הפורום המתאים...... ואם את לא מאמינה, זה מה שיש לממשלת ארה"ב להגיד בנושא: -------------------------------------------------------------------------------- Information provided by: Association of Women s Health, Obstetric and Neonatal Nurses (AWHONN) International Food Information Council (IFIC) Foundation U.

Safe Food Handling for a Healthy Pregnancy When you're expecting, it's natural to be concerned about your health and that of your unborn baby. Maintaining a healthful diet, drinking plenty of liquids, and taking prenatal vitamins are all important for the health of the expectant mother and her baby. Food safety is also very important. This information will help you make safe decisions when selecting and preparing food for yourself and/or your family. Sometimes, what we eat can make us sick. Food contaminated by harmful bacteria can cause serious illness. One type of bacteria, Listeria monocytogenes ( pronounced lis-TIR-ee-ya mon-o-si-TAH-gin-eez) , can cause an illness called listeriosis. The Centers for Disease Control and Prevention ( CDC) estimates that 2,500 people become seriously ill with listeriosis each year in the United States. Of these, one in five die from the disease. Listeriosis can be particularly dangerous for pregnant women and their unborn babies. Foodborne illness caused by Listeria in pregnant women can result in premature delivery, miscarriage, fetal death, and severe illness or death of a newborn from the infection. What is Listeria? Listeria is a type of bacteria found everywhere in soil and ground water and on plants. Animals and people can carry Listeria in their bodies without becoming sick. Despite being so widespread, most infections in humans result from eating contaminated foods. Most people are not at increased risk for listeriosis. However, there are some people who are considered at risk because they are more susceptible to listeriosis. In addition to pregnant women and their unborn babies and newborns, other at-risk groups include older adults and people with weakened immune systems caused by cancer treatments, AIDS, diabetes, kidney disease, etc. By carefully following food safety precautions, persons at risk for listeriosis can substantially reduce their chances of becoming ill. Why is listeriosis especially dangerous for me and my child? Hormonal changes during pregnancy have an effect on the mother s immune system that lead to an increased susceptibility to listeriosis in the mother. According to the CDC, pregnant women are about 20 times more likely than other healthy adults to get listeriosis. In fact, about one-third of listeriosis cases happen during pregnancy. Listeriosis can be transmitted to the fetus through the placenta even if the mother is not showing signs of illness. This can lead to premature delivery, miscarriage, stillbirth, or serious health problems for her newborn. Is Listeria transmitted from the mother to the baby through breast milk? While there is a theoretical possibility that Listeria monocytogenes could be transmitted via mother's milk, this has never been proven. How will I know if I have listeriosis? Because the symptoms of listeriosis can take a few days or even weeks to appear and can be mild, you may not even know you have it. This is why it's very important to take appropriate food safety precautions during pregnancy. In pregnant women, listeriosis may cause flu-like symptoms with the sudden onset of fever, chills, muscle aches, and sometimes diarrhea or upset stomach. The severity of the symptoms may vary. If the infection spreads to the nervous system, the symptoms may include headache, stiff neck, confusion, loss of balance, or convulsions. Consult your doctor or healthcare provider if you have these symptoms. A blood test can be performed to find out if your symptoms are caused by listeriosis. What is the treatment for listeriosis? During pregnancy, antibiotics are given to treat listeriosis in the mother. In most cases, the antibiotics also prevent infection of the fetus or newborn. Antibiotics are also given to babies who are born with listeriosis. What steps can I take to prevent listeriosis? USDA's Food Safety and Inspection Service (FSIS) and the U. S. Food and Drug Administration (FDA) provide the following advice for pregnant women and all at-risk consumers: : Do not eat hot dogs, luncheon meats, or deli meats unless they are reheated until steaming hot. Do not eat soft cheeses such as feta, Brie, Camembert, blue-veined cheeses, and Mexican-style cheeses such as "queso blanco fresco." Hard cheeses, semi-soft cheeses such as mozzarella, pasteurized processed cheese slices and spreads, cream cheese, and cottage cheese can be safely consumed. Do not eat refrigerated pגtי or meat spreads. Canned or shelf-stable pגtי and meat spreads can be eaten. Do not eat refrigerated smoked seafood unless it is an ingredient in a cooked dish such as a casserole. Examples of refrigerated smoked seafood include salmon, trout, whitefish, cod, tuna, and mackerel which are most often labeled as "nova-style," "lox," "kippered," "smoked," or "jerky." This fish is found in the refrigerated section or sold at deli counters of grocery stores and delicatessens. Canned fish such as salmon and tuna or shelf-stable smoked seafood may be safely eaten. Do not drink raw (unpasteurized) milk or eat foods that contain unpasteurized milk. What can all consumers do to prevent listeriosis and keep their food safe? Because Listeria can grow at refrigeration temperatures of 40 ÷F or below, FSIS and FDA advise all consumers to: Use all perishable items that are precooked or ready-to-eat as soon as possible. Clean their refrigerators regularly. Use a refrigerator thermometer to make sure that the refrigerator always stays at 40 ÷ F or below. What should I do if I've eaten a food that has been recalled because of Listeria contamination? If you have eaten a contaminated product and do not have any symptoms, most experts believe you don t need any tests or treatment, even if you are pregnant. However, you should inform your physician or healthcare provider if you are pregnant and have eaten the contaminated product, and within 2 months experience flu-like symptoms. It's important to learn how to protect yourself and your unborn baby from foodborne illnesses. Getting in the habit of eating a safe and nutritious diet not only benefits your baby, but will also give you peace of mind. Remember - new information on food safety is constantly emerging. Recommendations and precautions are updated as scientists learn more about preventing foodborne illness. You need to be aware of and follow the most current information on food safety. Consult your healthcare provider if you have questions.
