19,983 cases of diarrhoea throughout Sabah, Malaysia from January 1971 to December 1978 were bacteriologically examined for Shigella. A total of 241 Shigella isolates representing 9 serotypes were encountered. S. flexneri and S. sonnei accounted for 69.7% and 29.5% of the isolates respectively. S. flexneri type 2 was very common and comprised 47% of the flexneri strains. S. flexneri types 5.6 and Y were rarely found. Only two cases of S. boydii were isolated. S. dysenteriae was not encountered. Isolation rates ranged from 0.64% to 1.73% while the percentages or cases of diarrhoea bacteriologically examined in relation to the number notified range from 13.7 to 29.6. Kota Kinabalu. Tawau and Sandakan accounted for 50.6%. 21.2% and 8.2% of Shigella isolates respectively. However. no isolations were made from Lahad Datu, Semporna and Victoria [Labuan Island]. S. flexneri type 5 was only found in Sandakan while S. flexnert type Y was isolated from Kota Kinubulu. No S. Sonnel was found in Ranau and Tenom.
The puffer fish belongs to the family Tetraodontidae and has one identifying characteristic which is the ability to inflate itself by gulping in large quantities of air or water. They are commonly found in estuarine and inshore water. The viscera (ovaries, testes and liver) of puffer fish contain varying amounts of extremely potent toxins [tetraodontoxin). The most violent form of fish poisoning is produced by ingestion of tetraodontoid or puffer-like fishes and this has been reported. The putftoad, Tetradon maculatum, has caused fatal poisoning? Despite the high toxicity of this group of fish, the meat is commonly consumed by some fisherman in Sabah without much morbidity. In Japan, puffer fish, called "fuqu" commands the highest prices in food fish and are prepared and sold in special restaurants where specially trained cooks are employed to prepare the "fuqu". Nevertheless it is still the primary cause of food poisoning in Japan especially among the lower socio-economic classes who fail to take the necessary precautions. In Sabah, four cases of puffer fish poisoning resulting in one death have been documented." We report herewith another incidence of puffer fish poisoning in which 18 persons from seven families were affected with nine deaths from two families.
