Objectives. To document the number of farms operating a 'dop' system (
payment of workers with alcohol instead of wages), to estimate the num
ber of farm workers affected, to describe how the system operated and
to characterise adverse social conditions on the farms. Population. Fa
rms served by the mobile clinics of the Cape Metropolitan Council's He
alth Department in the Stellenbosch area. Methods. Cross-sectional pre
valence survey. Nurses collected data from patients attending mobile c
linics. Results. A prevalence of 9.5% was detected in respect of farms
operating the dop system, with an estimated 780 workers affected. The
most common practice was a daily provision of 750 ml wine to male wor
kers. Social conditions on the farms in question were poor and wages w
ere low. Child malnutrition was the most common health problem identif
ied. Conclusion. The dop system, although illegal, has been documented
to occur in the Stellenbosch area. Programmes to address the dop syst
em and alcohol abuse, based on a primary health care approach, are a p
riority in the rural areas of the Western Cape.
