What risks does it pose?
What options are there?
Shark, King Mackerel, Swordfish, and Tilefish
Methylmercury
Can harm the nervous system of an unborn baby or a young child. Methylmercury can remain in an adult's system for one year after ingestion, so consider whether this toxin will be present in your system before trying to conceive.
Continue to eat other types of fish. It has been shown to increase the brain growth in a fetus. It is also a great source of protein and low in fat. Therefore, it's a good addition to a healthy diet plan. Expectant and breastfeeding mothers can eat up to 12 oz. of low-mercury fish in a week including: shrimp, salmon, pollock, catfish, and canned tuna. However, these women should eat no more than 6 oz. of (albacore) white tuna in any given week.
Shellfish (oysters and clams) and Sushi

Fish should be fully cooked until it easily flakes with a fork. It will appear opaque in coloration and will register an internal temperature of 145 degrees Farenheit.
Game fish (trout, salmon, or bass)
Industrial pollutant: PCB's
(Polychlorinated biphenyls)
May cause learning problems, decreased IQ, and reduced birth weight in an unborn fetus.
Check first with local health department to determine risk of pollution. Also check with the Environmental Protection Agency to determine if mercury warnings have been issued in your area.
Hot Dogs or Lunch Meats (Ham, Turkey,Salami, Bologna, Corned Beef, Roast Beef, etc.)
Listeriosis (form of food poisoning)
Can cause miscarriage, still births, or premature delivery. If baby is born with listeriosis, the baby can become seriously ill and possibly die. Only safe if reheated until steaming hot.
Soft Cheeses (Feta, Brie, Queso Blanco, Queso Fresco, Panela, Camembert, Roquefort, blue -veined, and any other cheese that has not been made with pasteurized milk.

Refrigerated pates, meat spreads, or smoked seafood (unless previously cooked)
Listeriosis (form of food poisoning)

Unpasteurized milk products
Listeriosis (form of food poisoning)
Can cause miscarriage, still births, or premature delivery. If baby is born with listeriosis, the baby can become seriously ill and possibly die. Buy only pasteurized milk products.
Unpasteurized fruit and vegetable juices
Salmonella and E. Coli poisoning
Woman can become seriously ill. If they are pregnant, it can be passed on to their unborn child resulting in illness that may include: diarrhea, fever, and possibly meningitis (swelling of the brain).
Drink and eat only pasteurized fruit and vegetable products. All unpasteurized products should have a label that states that information. If unsure, don't. It's better to be safe than sorry.
Undercooked Meats
Toxoplasmosis (is also transmitted via cat feces)
Can cause vision and hearing problems in an unborn baby as well as possible mental retardation or seizures.
Make sure that all meat is cooked thoroughly. Pork, ground beef (hamburgers), and chicken should have no pink coloration at all after cooking. Beef, veal, and lamb may be slightly pink in the middle but should have an internal temperature of 145 degrees Fahrenheit. Pork and ground beef should reach an internal temperature of 160 degrees. Whole chicken and turkey should reach an internal temperature of 180 degrees. Chicken breasts should reach 170 degrees. Always use a meat thermometer!
Undercooked Eggs
Salmonella
Women can become seriously ill. If they are pregnant, it can be passed on to their unborn child resulting in illness that may include: diarrhea, fever, and possibly meningitis (swelling of the brain).
Eggs should be cooked until the egg whites and yolk are hard. Avoid foods with undercooked or raw eggs in the ingredients (i.e. cookie dough, hollandaise sauce, and egg nogg, etc.)
Liver
Vitamin A overdose
May cause birth defects.
While Vitamin A is necessary for appropriate growth in an unborn fetus, too much vitamin A can be toxic. Eating liver has not been directly linked to birth defects, but if you wish to continue eating liver while pregnant, make sure your multivitamin does not contain more than 5,000 International Units (I.U.'s) of preformed Vitamin A or take a multivitamin that does not contain Vitamin A.


Alcohol, Drugs, and Tobacco


Alcohol, Drugs, and Tobacco
Toxin
What risks does it pose?
What options are there?
Alcohol (Beer, wine, hard liquor, mixed drinks) Alcohol
Can cause birth defects such as fetal alcohol syndrome in offspring. This can damage the child's learning capacity and may result in mental retardation. In addition, prolonged and excessive drinking can cause severe liver damage for the mother.
Drink virgin (non-alcoholic) drinks. No one knows how much alcohol can hurt an unborn fetus. Therefore,it is recommended that all women of gestational age who might become pregnant should not drink alcohol. If you cannot stop drinking, contact a local support group or rehabilitation clinic for help.
(*See resource guide)
Drugs (Cocaine, marijuana, LSD, methamphetamines, heroine, etc.
Depends on the Drug
Can cause birth defects and possibly mental retardation in offspring. The infant can be born addicted to the drug and have to suffer through withdrawal. Negative health effects are reported with all illegal drugs.
Never put illegal drugs into your body. If you have a problem with an illegal substance, contact a local support group or rehabilitation clinic for help.
(*See resource guide)
Tobacco
There are many toxins found in tobacco and in tobacco smoke.
Smoking puts women at a much greater risk for heart disease, the nation's leading cause of death for women. It also puts women in danger of lung cancer among other smoking-related illnesses such as emphysema. Smoking during pregnancy can cause prematurity and low birth weight infants. Infants of smoking mothers are also at a much higher risk for SIDS (Sudden Infant Death Syndrome or "crib death").
Stop smoking. The sooner a woman quits during her pregnancy, the healthier the outcome for herself and her baby. Studies have proven that stopping smoking at any point in the pregnancy will yield some good results for the baby. The sooner you quit, the healthier your unborn baby will be. If you need help to quit smoking, please see
the resource guide located on this website for local organizations that can help you reach this goal.
