Cereulida em produtos alimentares: riscos, deteção e aspetos regulamentares

A cereulida é a toxina emética produzida por determinadas estirpes de Bacillus cereus e pode estar pré-formada diretamente nos produtos alimentares. Por este motivo, a deteção do microrganismo, por si só, nem sempre é suficiente para uma adequada avaliação do risco. O fator determinante é saber se a própria toxina está presente na amostra e em que concentração. Especialmente em categorias de produtos sensíveis, em casos suspeitos, reclamações ou amostras de retenção com resultados anómalos, a análise direta da cereulida fornece uma base sólida para garantir a segurança do produto, apoiar decisões de libertação de lote e prevenir recolhas de produtos do mercado.
