[Acute gastroenteritis due to Vibrio parahaemolyticus in Spain. Presentation of 8 cases].

Eight cases of acute gastroenteritis caused by Vibrio parahaemolyticus in humans are described; to our knowledge, they are the first such reported cases in Spain. All cases appeared between August 20th and October 15th, with a frequency of 8.3% regarding the overall adult patients with acute gastroenteritis, and 11.5% regarding the overall patients with positive stool culture for any enteropathogenic organism. The eight strains were Kanagawa positive and in three patients other enteropathogenic organisms were isolated in addition to Vibrio parahaemolyticus, i.e. Aeromonas hydrophila in two and Salmonella serovariety enteritidis in another. In all cases fish or shellfish had been ingested outside the patients' homes; except for one patient, who ate living clams in the seaside of Galicia, all patients ingested them at seaside restaurants from the Barcelona province. The clinical features of acute gastroenteritis were definite in all patients, but no patients had significant electrolyte losses or required hospital admission. Recovery was spontaneous and no antimicrobial agents were required. All strains were sensitive to tetracyclines, aminoglycosides, cefotaxime, ceftazidime and nearly always to co-trimoxazole.

Foodborne disease outbreaks of chemical etiology in Thailand, 1981-1987.

A study was conducted to determine the current situation of chemical foodborne outbreaks in Thailand for the period 1981-1987. Seventy-three outbreaks of chemical poisoning involving 1236 persons of whom 54 died were reported. Twenty outbreaks affecting 722 cases were caused by insecticide poisoning and methomyl was the most commonly recognized insecticide involved. Poisonous plants were responsible for 43 outbreaks with 420 cases. Mushroom poisoning was the most common entity (21 outbreaks, 211 cases), with plant seed poisoning next (9 outbreaks, 179 cases). There were 8 outbreaks following consumption of poisonous seafoods. Mussels were identified to be the vector in the outbreak of PSP. Horseshoe crabs which served as the vehicles for 4 outbreaks were also suspected to be associated with PSP. Puffer fish accounted for the remaining 3 outbreaks involving 6 cases of tetradotoxin poisoning. More complete reporting and more effort in outbreak investigations are needed for appropriate preventive and control measures.

Diseases from fish and shellfish ingestion.

Fish- and shellfish-acquired diseases are a common but often unrecognized group of food-borne illnesses with considerable epidemiologic importance. They present with a spectrum of gastrointestinal and neurologic symptoms, but the history of pertinent ingestion establishes the diagnosis. Treatment is generally supportive, and recovery with minimal or no residua is the rule. State and local health authorities should be notified of all suspected cases because of the frequent occurrence of multiple cases from one source.
