A presen\u00e7a de Escherichia coli nos alimentos<\/strong> continua a ser um dos principais desafios em mat\u00e9ria de seguran\u00e7a alimentar a n\u00edvel global. Embora muitas estirpes fa\u00e7am parte do microbiota intestinal normal de humanos e animais, determinadas variantes patog\u00e9nicas s\u00e3o respons\u00e1veis por surtos graves associados a produtos c\u00e1rneos, l\u00e1cteos e vegetais frescos.O aumento de surtos nas \u00faltimas d\u00e9cadas evidenciou a necessidade de aplicar estrat\u00e9gias integradas de controlo<\/strong><\/a>, desde a produ\u00e7\u00e3o prim\u00e1ria at\u00e9 ao consumidor final, sob uma abordagem baseada no risco e na gest\u00e3o preventiva. Neste artigo, veremos:\n

Escherichia coli \u00e9 uma bact\u00e9ria habitualmente presente no trato digestivo de animais e seres humanos. Devido \u00e0 sua abund\u00e2ncia intestinal, \u00e9 utilizada como indicador de contamina\u00e7\u00e3o fecal<\/strong> na \u00e1gua e nos alimentos.<\/p>\n
A maioria das estirpes \u00e9 comensal e inofensiva. No entanto, algumas variedades patog\u00e9nicas possuem informa\u00e7\u00e3o gen\u00e9tica que lhes permite:<\/p>\n
\n
Produzir toxinas (como as shiga toxinas)<\/li>\n
Aderir e invadir c\u00e9lulas intestinais<\/li>\n
Alterar o metabolismo celular<\/li>\n
Provocar destrui\u00e7\u00e3o tecidular<\/li>\n<\/ul>\n
Entre as estirpes de maior relev\u00e2ncia destacam-se as STEC (Shiga toxin-producing E. coli) e o seu subgrupo EHEC (Enterohemorrhagic E. coli)<\/strong>, especialmente o ser\u00f3tipo O157:H7, associado a diarreia hemorr\u00e1gica e, em casos graves, s\u00edndrome hemol\u00edtico ur\u00e9mico (SHU).<\/p>\n
Um aspeto cr\u00edtico do ponto de vista microbiol\u00f3gico \u00e9 a sua capacidade de troca gen\u00e9tica atrav\u00e9s de plasm\u00eddeos e bacteri\u00f3fagos<\/strong>, o que favorece o aparecimento de novas variantes mais virulentas ou resistentes aos antimicrobianos.<\/p>\n
A sua relev\u00e2ncia na seguran\u00e7a alimentar assenta em tr\u00eas fatores-chave:<\/p>\n
\n
Baixa dose infeciosa em determinadas estirpes.<\/li>\n
Elevada capacidade de sobreviv\u00eancia em diferentes matrizes alimentares.<\/li>\n
Possibilidade de transmiss\u00e3o ao longo de toda a cadeia alimentar.<\/li>\n<\/ol>\n<\/section>\n
\n
Principais vias de contamina\u00e7\u00e3o por E. coli nos alimentos<\/h2>\n
A contamina\u00e7\u00e3o por E. coli \u00e9 predominantemente de origem fecal<\/strong>, tanto humana como animal. As principais vias s\u00e3o:<\/p>\n
Contamina\u00e7\u00e3o na produ\u00e7\u00e3o prim\u00e1ria<\/strong><\/h3>\n

Contamina\u00e7\u00e3o durante o abate e a ordenha<\/strong><\/h3>\n
Os ruminantes, especialmente o gado bovino, s\u00e3o considerados o principal reservat\u00f3rio de STEC e EHEC. Nos produtos de origem animal, a contamina\u00e7\u00e3o ocorre habitualmente por:<\/p>\n
\n
Derrames intestinais durante o abate.<\/li>\n
Remo\u00e7\u00e3o inadequada da pele.<\/li>\n
Defici\u00eancias de higiene em matadouros.<\/li>\n

O crescimento bacteriano pode ocorrer quando n\u00e3o s\u00e3o controlados par\u00e2metros como:<\/p>\n
\n
Temperatura de armazenamento.<\/li>\n
pH.<\/li>\n
Atividade da \u00e1gua.<\/li>\n
Tempo de exposi\u00e7\u00e3o.<\/li>\n<\/ul>\n
Algumas estirpes podem tolerar condi\u00e7\u00f5es adversas, como ambientes \u00e1cidos em sumos ou produtos fermentados, o que aumenta a complexidade do controlo.<\/p>\n<\/section>\n

Uma grande variedade de alimentos pode atuar como ve\u00edculo de E. coli, dependendo da sua ecologia e das suas condi\u00e7\u00f5es de produ\u00e7\u00e3o.<\/p>\n

\n
Carne picada crua ou insuficientemente cozinhada.<\/li>\n
Carne fermentada.<\/li>\n
Leite cru e queijos n\u00e3o pasteurizados.<\/li>\n<\/ul>\n
A contamina\u00e7\u00e3o tem geralmente origem durante o abate ou a ordenha, sendo a carne fresca e o leite cru os ve\u00edculos mais habituais.<\/p>\n

\n
Alface.<\/li>\n
Espinafres.<\/li>\n
Mel\u00f5es.<\/li>\n
Cogumelos.<\/li>\n
Sementes germinadas.<\/li>\n<\/ul>\n
As sementes germinadas representam um risco significativo, uma vez que, durante o processo de germina\u00e7\u00e3o, pequenas contamina\u00e7\u00f5es iniciais podem multiplicar-se rapidamente at\u00e9 atingirem n\u00edveis infeciosos<\/p>\n

\n
Sumos n\u00e3o pasteurizados.<\/li>\n

Alimentos prontos a consumir (RTE).<\/li>\n<\/ul>\n
Nos alimentos processados, a sobreviv\u00eancia de poucas c\u00e9lulas vi\u00e1veis pode ser suficiente para causar doen\u00e7a se n\u00e3o forem aplicados tratamentos t\u00e9rmicos adequados ou m\u00faltiplas barreiras.<\/p>\n<\/section>\n

Controlo de E. coli na ind\u00fastria alimentar<\/h2>\n
O controlo eficaz de E. coli<\/strong><\/a> exige uma abordagem integrada, baseada em m\u00faltiplas barreiras e na gest\u00e3o preventiva do risco.<\/p>\n

A preven\u00e7\u00e3o de E. coli<\/strong> n\u00e3o pode ser abordada a partir de um \u00fanico ponto de controlo. Como indica a FAO no seu Quadro de Gest\u00e3o de Crises para a Cadeia Alimentar, \u00e9 necess\u00e1rio:<\/p>\n
\n
Identificar pontos cr\u00edticos ao longo de toda a cadeia.<\/li>\n
Aplicar interven\u00e7\u00f5es diferenciadas de acordo com a variante epidemiol\u00f3gica.<\/li>\n
Adotar uma abordagem interdisciplinar que integre sa\u00fade animal, produ\u00e7\u00e3o vegetal e sa\u00fade p\u00fablica.<\/li>\n<\/ul>\n
A chave j\u00e1 n\u00e3o \u00e9 apenas reagir a surtos, mas antecipar o risco e conceber sistemas preventivos robustos<\/strong><\/a>, capazes de minimizar a probabilidade de contamina\u00e7\u00e3o e proteger tanto o consumidor como a reputa\u00e7\u00e3o empresarial.<\/p>\n
