If you are among the approximately 30 percent of the population who’s already been exposed to Toxoplasma, you have antibodies that will protect your unborn child from the disease. Your health care provider can check your antibody levels and advise you.
If you do not have antibodies to Toxoplasma, you should take steps to prevent infection during pregnancy, since it can increase the risk of miscarriage, eye problems, and brain damage in your unborn child.
Fortunately, it’s easy to prevent infection once you know a little about Toxoplasma.
A cat gets infected by ingesting the organism encysted in the muscles of a rodent, bird, or other animal. To prevent this, confine Myrtle indoors to keep her from eating wildlife, and feed her commercially processed cat food, not raw food.
Cats with toxo rarely show signs of infection. However, they do excrete noninfectious Toxoplasma eggs, called oocysts (OH'-oh-sists), in their feces during the first few weeks after they’re infected.
More than one day is required for the oocysts to become infective, so you should scoop Myrtle’s litter boxes at least once daily. Wear a mask and disposable gloves, and wash your hands afterward. Or, better yet, have another adult scoop the litter boxes.
Oocysts excreted into sand and soil are a risk, so cover sandboxes when not in use and wash hands after outdoor play. Wear gloves while gardening, wash your hands afterward, and wash all fruits, vegetables, and herbs before eating them.
Undercooked animal muscle, unpasteurized milk, and cheese made from raw milk are other sources of Toxoplasma exposure. Use a food thermometer to ensure that meat, poultry, fish, and shellfish are cooked thoroughly, and don’t taste food until it’s fully cooked. Wash cutting boards and utensils in hot, soapy water, and always wash your hands before eating.
If you take these simple precautions, you can safely live with Myrtle while you’re pregnant. Best wishes to you and your new baby!
Grapes at “doses” of 0.32 to 2.4 ounces per pound of the dog’s body weight and raisins at 0.045 to 0.59 ounces per pound are toxic to dogs.
Initial signs of poisoning include vomiting, diarrhea, abdominal pain, excessive drooling, lethargy, dehydration, and loss of appetite. Immediate veterinary care is necessary to preserve kidney function and save the dog’s life.
Veterinary toxicologists theorize that the tartaric acid and potassium bitartrate in grapes, raisins, and tamarinds are responsible for the fruits’ toxicity in dogs.
The concentrations of these chemicals vary with the type of grape, growing conditions, and degree of ripening. That’s probably the reason why grapes and raisins sometimes cause no problems but other times are deadly.
Cream of tartar, used in cooking and baking, is another term for potassium bitartrate. Not surprisingly, cream of tartar ingestion also causes vomiting and kidney damage in dogs.
While grapes, raisins, tamarinds, and cream of tartar are safe for humans, they are toxic to dogs, so keep them away from your canine family members.
