“…For example, Cronobacter species have been found associated with dried dairy protein products (milk and cheese protein powders), cereals, candies such as licorice and lemon-flavored cough drops, dried spices, teas, nuts, herbs, and pastas and water [4,[23][24][25]. It has also been found associated with many different ready-to-eat and frozen vegetables, insect body surfaces and intestinal contents, and man-made environments such as PIF or dairy powder production facilities, and household sink drains [23,24,[26][27][28][29].…”

The Secretion of Toxins and Other Exoproteins of Cronobacter: Role in Virulence, Adaption, and Persistence

et al. 2020

Cronobacter species are considered an opportunistic group of foodborne pathogenic bacteria capable of causing both intestinal and systemic human disease. This review describes common virulence themes shared among the seven Cronobacter species and describes multiple exoproteins secreted by Cronobacter, many of which are bacterial toxins that may play a role in human disease. The review will particularly concentrate on the virulence factors secreted by C. sakazakii, C. malonaticus, and C. turicensis, which are the primary human pathogens of interest. It has been discovered that various species-specific virulence factors adversely affect a wide range of eukaryotic cell processes including protein synthesis, cell division, and ion secretion. Many of these factors are toxins which have been shown to also modulate the host immune response. These factors are encoded on a variety of mobile genetic elements such as plasmids and transposons; this genomic plasticity implies ongoing re-assortment of virulence factor genes which has complicated our efforts to categorize Cronobacter into sharply defined genomic pathotypes.

“…Disease outbreak based on RTEv contamination has been said to increase with about two hundred percent between 2009 and 2014 (Beneduce et al, 2017). Thus studies focusing on the microorganism (bacteria and viruses) as well as resistant organisms' presence in vegetables have been reported across Europe (Beneduce et al, 2017;Berthold-Pluta, Garbowska, Stefańska, & Pluta, 2017;Terio et al, 2017), Africa (Ssemanda et al, 2017;Quansah, Kunadu, Saalia, Díaz-Perez, & Chen, 2018), America (Byrne, Hofer, Vallim, & Almeida, 2016;González, Cadona, Sanz, Bustamante, & Sanso, 2017) and Asia (Faour-Klingbeil, Murtada, Kuri, & Todd, 2016;Wang, Qiao, Chen, Su, & Zhu, 2015;Kim et al, 2015). Such microorganism contaminations have been traced to the following factors: contamination from pre-and post-harvest handling, Resistance of microbes to disinfectant method(s), quality of irrigation water, bad sanitation and lack of cleaning, lack of adequate information by workers within the processing industries and sales outlets, lack of adequate information to consumers, loose handling of wash water and inappropriate transportation and inadequate storage respectively.…”

Wastewater conservation and reuse in quality vegetable cultivation: Overview, challenges and future prospects

The serious water scarcity experienced across the globe and the desire for sufficient food production all year round to combat hunger, poverty and malnutrition necessitate the need for wastewater reuse in irrigation. Wastewater has varied compositions that affect the growth of different crops positively, they may also be a source of dangerous pollutant. Heavy consumption of vegetables have been encouraged for its nutritional and health advantages. Hence, their production and cultivation have increased globally. While the nutritional advantage of vegetables is appealing, their high susceptibility to harbor and spread pathogenic microbes call for serious concern. Activities such as transportation, improper handling and packaging amongst others are sources of vegetable contamination. Irrigation water and techniques however present greater danger. Agro-industrial wastewater of a ready-to-eat vegetable (RTEv) industry operating a closed system may reintroduce microbes to vegetable gardens. The use of raw domestic wastewater, either black or grey water in vegetable cultivation presents attendant challenges which must be handled with utmost precaution. This review is focused on the dangers associated with the reuse of agro-industrial and domestic wastewater, precautions required as well as possible preventive/reduction measures. The possible dangers associated with "crude irrigation techniques" used in vegetable cultivation in the Southwestern part of Nigeria are presented. This work will no doubt serve as a tool for policy makers and environmentalists in enlightenment and awareness campaigns in educating most rural dwellers who are ignorant of these dangers.

“…Strains to be analyzed in this study were isolated from market products of plant origin by Berthold-Pluta et al [13] (the isolates were subjected to genetic identification and differentiation by 16S rDNA sequencing, PCR-RFLP analysis, and RAPD-PCR). They included: 13 strains of Cronobacter sakazakii (s12, s14, s21, s22, s41, s42, s44, s45, s47, s48, lv25, lv27, lv28), four strains of C. muytjensii (s16, s34, s50, s51), two strains of C. turicensis (lv53, lv54), 1 strain of C. condimenti (s37), and one strain of C. malonaticus (lv31) ( Table 1).…”

“…All these traits allow these microorganisms to survive under conditions of food production processes [10,11]. Bacteria belonging to the genus Cronobacter have been isolated from various food products, including these intended for infants and children, from dairy and meat products, plantderived foods, water, and others [12][13][14][15][16][17][18][19][20].…”

Essential oils (EOs) are liquid preparations produced from plant materials. Their use as inhibitors of the growth of spoilage and pathogenic microorganisms is a good alternative to the chemical additives in foods. The disc-diffusion method was used to screen the EOs from thyme, cinnamon, clove, peppermint, marjoram, cumin, rosemary, fennel, basil, lime, bergamot orange, orange, lemon, grapefruit, mandarin, cardamom, anise, and ginger, against 21 strains of Cronobacter species, including: C. sakazakii, C. muytjensii, C. turicensis, C. condimenti, and C. malonaticus. In addition, the minimum inhibitory concentration (MIC) and the maximum tolerable concentration (MTC) of thymol, trans-cinnamaldehyde, eugenol, and menthol were determined for five strains of Cronobacter spp. The most effective EOs were: thyme > cinnamon > marjoram. In turn, EOs from clove, cumin, and fennel had a moderate inhibiting effect against only some of the analyzed strains. The majority of the tested EOs: peppermint, rosemary, basil, cardamom, anise, ginger, and all EOs from citrus fruits were ineffective against all the studied strains.
