Abstract
To the Editor.— The renewed interest in meat-wrappers' respiratory problems (235:915; 937; 943, 1976) is pleasing, particularly in the light of three unexpected disappointments in the three years since we wrote our original report on meat-wrappers' asthma 1 : (1) the hot-wire technique for cutting polyvinyl chloride (PVC) has not been eliminated; (2) the existence of any association between reversible bronchospastic disease and meat wrapping is still questioned 2 ; (3) a prospective study designed to define the incidence, prevalence, and long-term morbidity, if any, of this condition remains to be done. Although we have been unable to get the support necessary to do a randomized longitudinal study of pulmonary function in meat wrappers, I understand that such a large-scale study will be undertaken elsewhere. Until this is done, further anecdotes may be helpful to the practicing physician. I know of at least two disabled meat wrappers who remain free of symptoms
