PATHOGENS 27/10/21 The Persistence of Bacterial Pathogens in Surface Water and Its Impact on Global Food Safety. Water is vital to agriculture.
It is essential that the water used for the production of fresh produce commodities be safe. Microbial pathogens are able to survive for extended periods of time in water. It is critical to understand their biology and ecology in this ecosystem in order to develop better mitigation strategies for farmers who grow these food crops. In this review the prevalence, persistence and ecology of four major foodborne pathogens, Shiga toxin-producing Escherichia coli (STEC), Salmonella, Campylobacter and closely related Arcobacter, and Listeria monocytogenes, in water are discussed. These pathogens have been linked to fresh produce outbreaks, some with devastating consequences, where, in a few cases, the contamination event has been traced to water used for crop production or post-harvest activities.
MICROORGANISMS 23/09/21 Zero-Valent Iron Filtration Reduces Microbial Contaminants in Irrigation Water and Transfer to Raw Agricultural Commodities. Groundwater depletion is a critical agricultural irrigation issue, which can be mitigated by supplementation with water of higher microbiological risk, including surface and reclaimed waters, to support irrigation needs in the United States.
Zero-valent iron (ZVI) filtration may be an affordable and effective treatment for reducing pathogen contamination during crop irrigation. This study was performed to determine the effects of ZVI filtration on the removal and persistence of Escherichia coli, and pepper mild mottle virus (PMMoV) in irrigation water. Water was inoculated with E. coli TVS 353, filtered through a ZVI filtration unit, and used to irrigate cucurbit and cruciferous crops.

The risk assessment of nitrosamines in pool water was reported firstly. The reliability of using THMs as the sole standard for DBPs was discussed. WATER 17/02/21 Electrochemical Treatment of Effluent for the Removal of Contaminants of Emergent Concern and Culturable Microorganisms. The present work aims to study the electrochemical (EC) process applied for the removal of contaminants of emergent concern (CECs) from wastewater after secondary treatment and the effect of the process on the total culturable microorganisms.
The EC experiments were performed in a cylindrical open reactor with 500 mL of effluent, and a fixed current density of 8 mA/cm² was applied through mixed metal oxide electrodes. The experiments were conducted in different sets. In the first round (Set 1), the effluent sample was spiked with three CECs (200 ppb each): caffeine (CAF), carbamazepine (CBZ), and oxybenzone (OXY). FOOD SAFETY MAGAZINE - AOUT 2020 - The Growing Challenge of Safe Water for Use in Food Processing Operations. Water | August/September 2020 By Larry Keener, CFS, PA, PCQI An old adage of oenophiles and epicureans says: “If the wine isn’t fit for drinking, then it’s not fit for use in cooking.”
The same is true for water. If your water supply is of poor quality, then it is a reasonable assumption that its use in food processing would have an adverse effect on the organoleptic properties of that food or, more importantly, on its safety. When a potable water supply, drinking water, contains lead, manganese, pharmaceutical compounds, pesticides, radionuclides, or “forever chemicals” (such as per- and polyfluoroalkyl substances or PFAS), then it should probably be prohibited from use in the production of human food, but the reality on the ground may be different. Environmental Sciences Europe 18/01/20 Persistent, mobile and toxic substances in the environment: a spotlight on current research and regulatory activities.
A recent example demonstrates the relevance of organic micropollutants for drinking water supply: In 2016, concentrations of more than 20 µg L−1 trifluoroacetate (TFA) were detected in the bank filtrate of the river Neckar (Germany) .
Résumé traduit : Certaines substances persistantes et polaires peuvent présenter un danger pour les ressources en eau potable. Afin de favoriser l'échange de connaissances dans ce domaine, le Groupe de travail Surveillance environnementale de la Division de la chimie environnementale et de l'écotoxicologie de la Société allemande de chimie (GDCh) a discuté lors de sa réunion de décembre 2018 de l'importance et de la pertinence des produits chimiques persistants, mobiles et toxiques (substances PMT) dans l'environnement. Cinq contributions orales ont mis en évidence non seulement divers aspects tels que l'identification de substances PMT potentielles sur la base de certaines propriétés et leur éventuelle réglementation dans le cadre du règlement européen REACH, mais également les développements actuels dans l'analyse des substances PMT et les résultats de la surveillance environnementale. Les données présentées prouvent que de nombreuses substances persistantes et mobiles peuvent être détectées dans les eaux de surface. Une fois détecté, il peut être complexe et coûteux d'identifier les sources et de réduire les intrants, comme le montre une étude de cas sur le 1,4-dioxane dans les eaux de surface bavaroises. Il en va de même pour l'élimination des substances polaires de l'eau brute pour la production d'eau potable. Aujourd'hui, les progrès scientifiques des méthodes d'analyse facilitent l'identification et la quantification des substances même très polaires dans les échantillons d'eau. Outre l'analyse ciblée des produits chimiques critiques, le dépistage non ciblé joue un rôle de plus en plus important. Cela ouvre la possibilité de détecter des substances dans des échantillons d'eau qui n'ont pas encore été étudiées dans le cadre de la surveillance de routine et de tester leur pertinence pour l'homme et l'environnement. Cependant, la liste des substances PM potentiellement présentes qui n'ont pas encore été étudiées est encore très longue. D'autres améliorations méthodologiques semblent ici nécessaires. Compte tenu des preuves de la présence de substances PMT dans l'environnement (par exemple, acide trifluoroacétique et 1,4-dioxane) et des risques potentiels pour le captage d'eau potable, il semble important, compte tenu du principe de précaution, d'identifier et de hiérarchiser REACH pertinent - substances enregistrées. L'évaluation doit être basée sur les propriétés intrinsèques et le potentiel d'émission des composés. La mise en œuvre d'une proposition détaillée faite au niveau européen pour réglementer les PMT et les substances très persistantes et très mobiles (vPvM) dans le cadre de REACH garantirait que les produits chimiques identifiés comme étant des substances extrêmement préoccupantes selon les critères PMT et vPvM soient soumis à autorisation à l'avenir. – guatemalt
This caused nationwide attention and led to further analyses of the occurrence of TFA in surface, ground and drinking water.
It was shown that the Rhine is also influenced by the identified point source at the Neckar and that this affects drinking water supply more than 300 km downstream.

PLOS 12/04/18 Present-day monitoring underestimates the risk of exposure to pathogenic bacteria from cold water storage tanks. Abstract Water-borne bacteria, found in cold water storage tanks, are causative agents for various human infections and diseases including Legionnaires’ disease.
Consequently, regular microbiological monitoring of tank water is undertaken as part of the regulatory framework used to control pathogenic bacteria. A key assumption is that a small volume of water taken from under the ball valve (where there is easy access to the stored water) will be representative of the entire tank. To test the reliability of this measure, domestic water samples taken from different locations of selected tanks in London properties between November 2015 and July 2016 were analysed for TVCs, Pseudomonas and Legionella at an accredited laboratory, according to regulatory requirements.

ITALIAN JOURNAL OF FOOD SAFETY - 2016 - A culture independent method for the detection of Aeromonas sp. from water samples. Abstract The genus Aeromonas is present in a wide variety of water environments and is recognised as potentially pathogenic to humans and animals. Members of this genus are often confused with Vibrio when using automated, commercial identification systems that are culture-dependent. This study describes a polymerase chain reaction (PCR) detection method for Aeromonas that is culture- independent and that targets the glycerophospholopid-cholesterol acyltransferase (gcat) gene, which is specific for this genus. The GCAT-PCR was 100% specific in artificially inoculated water samples, with a detection limit that ranged from 2.5 to 25 cfu/mL.

This work presents a new and unbiased method of risk ranking chemicals based on the threat they pose to the aquatic environment. The study ranked 12 metals, 23 pesticides, 11 other persistent organic pollutants (POPs), 13 pharmaceuticals, 10 surfactants and similar compounds and 2 nanoparticles (total of 71) of concern against one another by comparing their median UK river water and median ecotoxicity effect concentrations.
To complement this, by giving an assessment on potential wildlife impacts, risk ranking was also carried out by comparing the lowest 10th percentile of the effects data with the highest 90th percentile of the exposure data. In other words, risk was pared down to just toxicity versus exposure. Further modifications included incorporating bioconcentration factors, using only recent water measurements and excluding either lethal or sub-lethal effects.
