Norovirus poisoning resulted from contaminated fruit or vegetables consumption and prevention methods

Abstract

Fruits and vegetables is considered to be low–risk foods in terms of food safety in the food safety management system. However Norovirus and other pathogen contamination should not be ignored in fruits and vegetables. Norovirus which has 39% and 26% shares respectively in fruits and vegetables sourced food poisoning and take place on the top in pathogens. In addition, properties such as frequency of occurrences and the effect intensity of pathogenic factors like (or as) Norovirus should be involved in the risk assessment processes in the entire process starting from the crop until it reaches the consumer. Although Norovirus causes significant share of food poisoning worldwide a few studies have been made on Norovirus caused food borne outbreaks. In this review, current information’s about reported Norovirus induced food poisonings in recent years and prevention methods were presented.

Kontamine olmuş meyve veya sebze tüketiminden kaynaklanan norovirüs zehirlenmeleri ve önleme yolları

Öz

Gıda güvenliği yönetim sistemlerinde meyve ve sebzeler gıda güvenliği açısından düşük riskli gıdalar olarak kabul edilmektedir. Ancak meyve ve sebzelerde olabilecek Norovirüs ve diğer patojen bulaşmaları göz ardı edilmemelidir. Meyve ve sebze kaynaklı gıda zehirlenmelerinde Norovirüs sırasıyla %39 ve %26’lık paya sahiptir ve patojenler içinde ilk sırada yer almaktadır. Ayrıca bitkisel üretimden başlanarak tüketiciye ulaşana kadar geçen tüm süreçlerde Norovirüs gibi patojen etmenlerin ortaya çıkma sıklığı ve etki şiddeti gibi özellikleri risk değerlendirme süreçlerine katılmalıdır. Bu derlemede dünya genelinde gıda zehirlenme nedenleri içinde önemli bir paya sahip olmasına rağmen üzerinde az sayıda çalışma yapılmış olan Norovirüsler hakkında güncel bilgiler ve son yıllarda gerçekleşmiş ve kayıt altına alınmış Norovirüs kaynaklı gıda zehirlenmeleri ve bu zehirlenmelere karşı alınabilecek tedbirler sunulmuştur.
