"This book should be on the shelf at every hospital and county health department in agricultural communities, and at every referral center that receives patients from these communities...Chapter 1 presents a superlative overview of the broad topic of agricultural medicine... This chapter is a must-readindeed, should be required reading in medical schools...There are other features of this volume that enhance its value. It is well referenced...amply illustrated...Prevention is a theme throughout the book...its emphasis is farmer occupational safety. Offering a global perspective, its relevance is not limited to health care professionals in North America or Europe. The presentation is eminently practical, typified by the instructions on assembling an agricultural first aid kit...Health conditions of significance to farm workers are discussed at suitable length: not too concise, not too detailed."
