Abstract
Sodium fluoroacetate is an organofluorine compound toxic to mammals, insects, and birds, currently registered for use only in
livestock protection collars as a predacide in some North American states, with restricted use in California. A flock of 445 lambs
and ewes in California were moved into a native pasture on a municipal refuse disposal site. Within 24 hours, 14 ewes were found
dead, and the remaining sheep were moved off the site. Both ewes and lambs exhibited disoriented running, followed by apparent
blindness, weakness, ataxia, coma, and death. Over the next 4 days, 63 ewes and 80 lambs died with a peak at 3 days after grazing
the suspect pasture (157/445, 35% mortality). Two dead 4-month-old lambs and 2 ewes were submitted to the California Animal
Health and Food Safety laboratory for necropsy. Grossly, there were bilateral diffuse pulmonary congestion and edema, hydrothorax
and hydropericardium with fibrin clots, and multifocally extensive areas of epicardial petechiae, ecchymoses, and pallor. In
1 ewe, there was regional caudodorsal pulmonary hemorrhage and intraluminal tracheal clotted blood. Microscopically in all
cases, there was multifocal acute myocardial degeneration and necrosis with nonsuppurative pleocellular myocarditis. Sodium
fluoroacetate was detected in kidney from a lamb and a ewe at 27.5 and 12.5 parts per billion, respectively. All sheep were selenium
deficient, and concurrent copper deficiency was diagnosed in 3. The pathological and toxicological findings were consistent
with 1080 poisoning, possibly exacerbated by micronutrient deficiency. This outbreak raised an alert about the use of restricted
products with potential lethal effect in animals in California. MenosAbstract

ABSTRACT.
The growth of demand of organic products has increased the interest of growers all around the World. To reach a sustainable organic production system, growers have to go through a long and difficult process. Eighty-one successful organic production systems in the Southern Cone of America were evaluated regarding management practices, such as disease control, soil fertility, and biodiversity management. The aim of the study was to determine associations between production techniques, farmer training, experience in organic agriculture, yields obtained, and the contribution of organic production to the profitability of farmers. A multivariate analysis was performed to characterize the variability between systems, correlate the management variables and explain economic sustainability. The economic sustainability of farmers was highly correlated with self-production of fungicides and insecticides, use of permitted commercial fertilizers, organic matter application, the use of natural enemies, commercially permitted fungicides and insecticides and the implementation of preventive practices for disease management. Pest monitoring correlated significantly with farmer training and sustainable practices implementation. Farmer?s perception on the importance of crop diversity in organic production correlated with the importance of external inputs independence, green manure, cover crop, and the experience of farmers in organic production. Farmers who implemented more management practices had yield losses below 20% of total production and a gross margin of organic farming of more than 1.5 times the minimum wage of the country than farmers that implemented few or no management practices.
