A protozoan organism called toxoplasma can be present in garden soil and can be harmful to the infants of pregnant women and those with a weakened immune system if proper precautions are not taken. Toxoplasmosis causes flu-like symptoms, such as swollen lymph glands or muscle aches and pains that last a month or longer. It can also cause mental disabilities and/or eye damage to infants who are infected while in the womb. More than 60 million people in the United States are likely carriers of the toxoplasma parasite, but very few have symptoms because the immune system usually keeps the parasite from causing illness. Toxoplasma can exist in soil when infected cat feces are present. Outdoor cats that eat mice are the most likely carriers. A cat can become infected by eating infected prey or being fed raw or undercooked meat infected with the parasite. Not all cats shed this organism all the time. An infected cat only sheds the organism for a few weeks. However, once it is in the soil, it can survive several months to a year or more, in spite of warm or cold weather. Dog feces do not cause toxoplasmosis, but can cause other problems. Toxoplasmosis is caused by hand to mouth contamination, and can come from sources other than infected garden soil. Some include eating meat that is not thoroughly cooked, contamination of knives, utensils, cutting boards and other foods that have had contact with raw meat and through contaminated drinking water. Though it is a serious threat, toxoplasmosis can easily be prevented by taking the appropriate precautions. To be properly protected if you are pregnant or have a weakened immune system, consider these tips.
· Always wear plastic or rubber gloves when gardening, and wash hands thoroughly when finished.
· Have someone else empty the cat litter if you have a house cat. Always wash your hands after petting or handling a cat.
· When preparing raw meat, wash cutting boards, sinks, knives and other utensils thoroughly with soap and hot water to avoid cross-contaminating other foods. Wash your hands well with soap and water after handling raw meat.
· Cook all meat thoroughly and until it is no longer pink in the center or until the juices become colorless. Do not taste meat before it is fully cooked.
· To help prevent your cat from becoming infected with toxoplasma, keep it indoors and feed it dry or canned cat food.
· Try to keep cats out of garden areas. Repellents are available, but it is impossible to guarantee they will work. It is best to assume the area is contaminated and always wear gloves and wash hands thoroughly.

- I live in Lindon and have heavy clay soil. I have been adding leaves and grass to my garden soil and it still compacts rapidly. Can I use the compost from the green and public waste dept. on a vegetable garden?

- I have heard that some of my tomatoes have tomato blight. What is it and how do identify it? The leaves on the plants curl and then the plant dies. However, the fruit still sets and matures as the plant is dying.
- I have had some raspberry plants in an area near my house (6' x 12') for over ten years and only in the spring do I try to gently loosen the soil with a gardening fork. I have not added anything other than some fruit oriented fertilizer or Miracle Grow in that time. Half of the section usually produces berries the size of the tip of your little finger and some grow as big as the tip of your thumb. The others are small and crumbly,which is okey of jam but not for visuals or overall production. I read that crumbliness is due to ovary infertility. How do I overcome that? Should I also be doing some thinning? Early this last spring I cut the canes to about three feet high but many of them are now close to eight feet long. What is the best way to deal with excess growth?
- By the end of June, our apple tree looked sickly, with faded, curling brown leaves. I am wondering if the leaves look the way they do because my husband doesn't spray regularly or because the tree is not getting enough water in our arid climate. When he does stick to a schedule, it seems that the leaves don't look much better. This is a tree that is nearly twenty years old. I have never noticed an infestation of bugs. Apples have gotten smaller and smaller by the year, most have worms. The tree is in our front yard and I really would like it to look healthy, regardless of whether or not we get eatable fruit. What should we do?
- I planted 2 plum trees several years ago. The 3rd year I had a huge crop. The next 2 years the leaves had what I think is peach leaf curl or at least that's how it made the leaves look. I sprayed both years with no improvement. This year I've also sprayed but after blossoming, the leafing is very sickly, the leaves done even really form, they just make tiny clusters of pale spikes that look like tiny curled leaves. Is there anything I can so short of digging them out? Can they be saved or I am better off just starting from scratch? How to I make sure what is there doesn't contaminate the new trees? Thanks.
