A major goal of studying farmworkers is to better understand how their work environment, including exposure to pesticides, affects their health. Although a number of health conditions have been associated with pesticide exposure, clear linkages have yet to be made between exposure and health effects except in cases of acute pesticide exposure. In this article, we review the most common health end points that have been studied and describe the epidemiologic challenges encountered in studying these health effects of pesticides among farmworkers, including the difficulties in accessing the population and challenges associated with obtaining health end point data. The assessment of neurobehavioral health effects serves as one of the most common and best examples of an approach used to study health outcomes in farmworkers and other populations exposed to pesticides. We review the current limitations in neurobehavioral assessment and strategies to improve these analytical methods. Emerging techniques to improve our assessment of health effects associated with pesticide exposure are reviewed. These techniques, which in most cases have not been applied to farmworker populations, hold promise in our ability to study and understand the relationship between pesticide exposure and a variety of health effects in this population.

The objective of this study was to elucidate the etiology and frequency of deaths in the United States from encounters with animals. The number of deaths from venomous and nonvenomous animals is reported annually to the US Department of Health and Human Services and published in Vital Statistics of the United States. This study is a survey of all animal-related fatalities listed as E-codes 905-906 reported in the Vital Statistics of the United States from 1979 through 1990. Data were extracted uniformly from the annual reports and analyzed using descriptive statistics. From 1979 through 1990, there were 1882 animal-related deaths in the United States. Venomous animals caused 718 deaths; nonvenomous animals caused 1164 deaths. Most deaths occurred among white males. The home site was the location of injury for the majority of deaths. The majority of venomous animal-related deaths were from hymenoptera; "other specified animal" caused the majority of nonvenomous deaths. An annual average of 157 deaths from animal attacks occurred in the United States between 1979 and 1990. Both fatal and nonfatal animal-related injuries are under-recognized public health hazards. Health care providers should educate their patients on exercising caution around animals, seeking medical care after an animal injury, carrying epinephrine kits if they have a history of systemic reactions to insect stings, and wearing helmets and other protective equipment when riding or working around large animals.

Although rare, venomous bites and stings during pregnancy may have a significant adverse effect on the fetus as well as the mother.

We found that approximately 1% of workplace fatalities are associated with an animal-related event. Methods to decrease the frequency of an animal injury are suggested.

Objective Injuries resulting from contact with animals and insects are a significant public health concern. This study quantifies nonfatal bite and sting injuries by noncanine sources using data from the National Electronic Injury Surveillance System–All Injury Program (NEISS-AIP). Methods The NEISS-AIP is an ongoing nationally representative surveillance system used to monitor all types and causes of injuries treated in US hospital emergency departments (EDs). Cases were coded by trained hospital coders using information from medical records on animal and insect sources of bite and sting injuries being treated. Data were weighted to produce national annualized estimates, percentages, and rates based on the US population. Results From 2001 to 2010 an estimated 10.1 million people visited EDs for noncanine bite and sting injuries, based on an unweighted case count of 169,010. This translates to a rate of 340.1 per 100,000 people (95% CI, 232.9–447.3). Insects accounted for 67.5% (95% CI, 45.8–89.2) of bite and sting injuries, followed by arachnids 20.8% (95% CI, 13.8–27.9). The estimated number of ED visits for bedbug bite injuries increased more than 7-fold—from 2156 visits in 2007 to 15,945 visits in 2010. Conclusions This study provides an update of national estimates of noncanine bite and sting injuries and describes the diversity of animal exposures based on a national sample of EDs. Treatment of nonfatal bite and sting injuries are costly to society. Direct medical and work time lost translates to an estimated $7.5 billion annually.

As the AgFF labor force includes a growing number of Latino immigrants, more research is needed to characterize a broad range of exposures and health outcomes experienced by this population, particularly in forestry and fisheries.

The number of fatal animal-vehicle collisions is increasing. Various methods to reduce such collisions are described, with fencing appearing to be the most effective. The use of personal restraints such as seat belts in passenger vehicles and helmets for motorcycle and all-terrain-vehicle riders may decrease fatalities during a collision.
