14,000 kilos of contaminated tuna trigger food poisoning outbreak in southern Spain

A 14,000 kilo batch of contaminated tuna has prompted the Junta de Andalucia to issue health warnings across the region after consumers fell ill in Cordoba, Granada, Jaen, Malaga and Sevilla.

The Andalucian Ministry of Health has reported more than 50 cases of histamine poisoning since May 5, all caused by fresh tuna originating from Garciden, an Almeria-based supplier.

Symptoms include a sore throat, headaches, hot flushes, sweating, nausea and vomiting.

An official statement advises consumers to avoid eating tuna purchased between April 25 and May 5, some of which may still be on sale.

Six batches with barcodes ending in 170501, 170502, 170503, 170504, 170505, and 170506 have been removed from the market.

Although tuna is naturally rich in histamine, poor hygiene during production, particularly exposure to high temperatures, may lead to a dangerous spike which cannot be removed by cooking or freezing.
