title: Haemolytic anaemia associated with Nigerian barbecued meat (red suya).
abstract: Five cases of haemolytic anaemia occurring in male Nigerians following the ingestion of spiced barbecued meat (suya) are described. Although suya is a popular food item in various parts of Nigeria, all five patients described in this report had consumed a special brand, called red suya, purchased from vendors at a popular road junction between the cities of Lagos and Ibadan. Ingestion of the culprit suya sample was followed within 24 h by malaise and fever, while passage of dark-coloured urine and jaundice followed 1-3 days thereafter. Glucose-6-phosphate dehydrogenase (G6PD) deficiency was demonstrated by a fluorescent screening test in all cases, while the enzyme phenotype was shown to be GdA- in all four cases studied by starch-gel electrophoresis, thus suggesting that G6PD deficiency was a predisposing factor in the cases reported in this series. The haemolytic disease was self-limiting and full recovery followed in all cases. In view of the markedly circumscribed range from where the patients originated, the culprit agent responsible for the haemolytic disease is believed to be a recently introduced food additive that is probably accessible only to a limited number of suya vendors.
