Home Gardens and Lead
Lead is a heavy metal that occurs in all soils but can reach hazardous levels in some soils as a result of leaded-fuel exhaust, industrial wastes and other causes. Learn how to test your soil for safety and see what you can do if lead levels run too high

Safety, efficacy, and tissues residues of ivermectin in reindeer
Safety, efficacy, and tissue residues of ivermectin, a broad spectrum parasiticide, were determined in Alaskan reindeer (Rangifer tarandus). Reindeer treated at 5 times and 10 times the standard dose of 200 mcg/kg had no detectable physical or behavioral reactions to ivermectin injected subcutaneously in the mid-cervical area. Ivermectin eliminated essentially 100% of reindeer warble larvae (Hypoderma (Oedemagena) tarandi). Tissue levels of ivermectin in back fat, injection site, muscle, liver, and kidney collected 3, 10, 17, and 24 days post injection were determined. All tissues levels rapidly declined and were approaching low unmea-surable amounts at the end of the 24 day test period. Ivermectin is a safe effective parasiticide that has been used successfully to threat thousands of reindeer in Alaska
Lead leaching in ceramics difficult to predict
From 1993 to 1997, UC nutrition, family and consumer sciences advisors in 21 counties
tested nearly 6,000 items of ceramic ware, of which 14.2% leached lead. More than
half of the items manufactured in Mexico (51.9%) tested positive for leached lead
with the UC Quick Lead Test. Ceramic ware from other countries, including the United
States, also tested positive. No factors, other than being made in Mexico, were found
to be useful predictors for lead leaching on any individual piece of ceramic ware.
Consumers concerned about the possible leaching of lead from their ceramic ware should
test each item individually
Antimicrobial susceptibility patterns of respiratory tract pathogens from sheep and goats
OBJECTIVE: To determine the antimicrobial susceptibility of common respiratory tract pathogens from sheep and goats.
DESIGN: Cross-sectional study.
SAMPLE POPULATION: 41 respiratory tract isolates from sheep and 36 isolates from goats.
PROCEDURES: Disk diffusion assay was used to determine antimicrobial susceptibility of isolates to amoxicillin-clavulanic acid, ceftiofur, ciprofloxacin, florfenicol, and tetracycline. Minimum inhibitory concentrations of florfenicol for these isolates were determined by use of the microbroth dilution technique.
RESULTS: The most common isolates were Pasteurella multocida (n = 28) and Mannheimia haemolytica (39). All isolates were susceptible to amoxicillin-clavulanic acid, ceftiofur, ciprofloxacin, and florfenicol. Five percent (4/77) of isolates were resistant to tetracycline.
CONCLUSIONS AND CLINICAL RELEVANCE: Susceptibility of respiratory tract pathogens isolated from sheep and goats to commonly used antimicrobial drugs in this study was high. Treatment of these species for bacterial respiratory tract disease is likely not complicated by antimicrobial resistanc
Livestock-Poisoning Plants of California
Horses, goats, sheep, and cattle can sicken or die if they eat from a poisonous plant. The best strategy is just to keep these plants out of reach. Here are photos, ID info, and poisoning symptoms for more than 30 hazardous ornamental and range plants
