Microbial safety of the fresh fruits is a global concern. The production of strawberry () in Iran has grown 4.5% from 2016 to 2019. Little information is available about the microbiological quality of strawberry produced in Iran. The objective of this investigation was to assess the fecal (FEC) contamination of fresh strawberries of south of Kerman province where is the centers of production and supply of strawberries to other parts of Iran.
In this cross-sectional descriptive study, the FEC of a total number of 109 strawberry samples, which were collected from green-houses of strawberry of Kerman province during three months, were enumerated using the most probable number (MPN) as described by Iranian National Standards Organization, protocol No.2946, and interpreted using the latest statute released by Iran Veterinary Organization, Executive order number 2946, released in 2011.
MPN of FEC counted in strawberries ranged between <0.3 (n=37) and >110 (n=19) per gram (g) having a mean, mode, and median value of 250.3, <0.3, and 9.4 MPN/g, respectively. More than one-fourth of the samples (28.44%) were polluted with FEC at a level of >100 MPN/g.
Our findings may be resulted from the sanitary quality of the farm and strawberries of the study area, which indicated that the microbial safety of the strawberries in this survey was not satisfactory, alarming public health.
新鲜水果的微生物安全性是全球关注的问题。2016年至2019年，伊朗草莓产量增长了4.5%。关于伊朗生产的草莓的微生物质量，现有信息很少。本调查的目的是评估克尔曼省南部新鲜草莓的粪便大肠菌群（FEC）污染情况，该地区是伊朗草莓生产和供应到其他地区的中心。
在这项横断面描述性研究中，按照伊朗国家标准组织第2946号协议所述的最可能数（MPN）方法，对在三个月内从克尔曼省草莓温室采集的总共109个草莓样本的FEC进行计数，并根据伊朗兽医组织2011年发布的第2946号行政命令的最新法规进行解读。
草莓中FEC的MPN范围为每克（g）<0.3（n = 37）至>110（n = 19），平均、众数和中位数分别为250.3、<0.3和9.4 MPN/g。超过四分之一的样本（28.44%）被FEC污染，污染水平>100 MPN/g。
我们的研究结果可能源于研究区域农场和草莓的卫生质量，这表明本次调查中草莓的微生物安全性不令人满意，对公众健康构成警示。
