    toxins Article Suspect and Target Screening of Natural Toxins in the Ter River Catchment Area in NE Spain and Prioritisation by Their Toxicity Massimo Picardo 1 , Oscar Núñez 2,3 and Marinella Farré 1,* 1 Department of Environmental Chemistry, IDAEA-CSIC, 08034 Barcelona, Spain; [email protected] 2 Department of Chemical Engineering and Analytical Chemistry, University of Barcelona, 08034 Barcelona, Spain; [email protected] 3 Serra Húnter Professor, Generalitat de Catalunya, 08034 Barcelona, Spain * Correspondence: [email protected] Received: 5 October 2020; Accepted: 26 November 2020; Published: 28 November 2020 Abstract: This study presents the application of a suspect screening approach to screen a wide range of natural toxins, including mycotoxins, bacterial toxins, and plant toxins, in surface waters. The method is based on a generic solid-phase extraction procedure, using three sorbent phases in two cartridges that are connected in series, hence covering a wide range of polarities, followed by liquid chromatography coupled to high-resolution mass spectrometry. The acquisition was performed in the full-scan and data-dependent modes while working under positive and negative ionisation conditions. This method was applied in order to assess the natural toxins in the Ter River water reservoirs, which are used to produce drinking water for Barcelona city (Spain). The study was carried out during a period of seven months, covering the expected prior, during, and post-peak blooming periods of the natural toxins. Fifty-three (53) compounds were tentatively identified, and nine of these were confirmed and quantified. Phytotoxins were identified as the most frequent group of natural toxins in the water, particularly the alkaloids group.

  • Alpha-Tomatine Content in Tomato and Tomato Products Determined By
    J. Agric. Food Chem. 1995, 43, 1507-151 1 1507 a-Tomatine Content in Tomato and Tomato Products Determined by HPLC with Pulsed Amperometric Detection Mendel Friedman* and Carol E. Levin Food Safety and Health Research Unit, Western Regional Research Center, Agricultural Research Service, U.S. Department of Agriculture, 800 Buchanan Street, Albany, California 94710 Tomato plants (Lycopersicon esculentum) synthesize the glycoalkaloid a-tomatine, possibly as a defense against insects and other pests. As part of an effort to improve the safety of plant foods, the usefulness of a new HPLC pulsed amperometric detection (PAD) method for the direct analysis of a-tomatine in different parts of the tomato plant; in store-bought and field-grown, including transgenic, tomatoes; in a variety of commercial and home-processed tomato products; and in eggplant and tomatillos was evaluated. The method was found to be useful for analysis of a variety of products including high-tomatine calyxes, flowers, leaves, roots, and stems of the tomato plant (14-130 mg/100 g of fresh weight), low-tomatine red tomatoes (0.03-0.08 mg/100 g), intermediate- tomatine tomatoes (0.1-0.8 mg/100 g), and high-tomatine fresh and processed green, including pickled and fried, tomatoes (0.9-55 mg/100 g). No experimental difficulties were encountered with extraction and analysis of tomatine in complex foods such as tomato juice, ketchup, salsa, sauce, and sun-dried tomatoes. Microwaving and frying did not significantly affect tomatine levels of tomato foods. The tomatine content of fresh market and transgenic delayed-ripening varieties was not different from the range ordinarily seen in tomato.

  • Poisonous Plants in New Zealand
    THE NEW ZEALAND MEDICAL JOURNAL Journal of the New Zealand Medical Association Poisonous plants in New Zealand: a review of those that are most commonly enquired about to the National Poisons Centre Robin J Slaughter, D Michael G Beasley, Bruce S Lambie, Gerard T Wilkins, Leo J Schep Abstract Introduction New Zealand has a number of plants, both native and introduced, contact with which can lead to poisoning. The New Zealand National Poisons Centre (NZNPC) frequently receives enquiries regarding exposures to poisonous plants. Poisonous plants can cause harm following inadvertent ingestion, via skin contact, eye exposures or inhalation of sawdust or smoked plant matter. Aim The purpose of this article is to determine the 15 most common poisonous plant enquiries to the NZNPC and provide a review of current literature, discussing the symptoms that might arise upon exposure to these poisonous plants and the recommended medical management of such poisonings. Methods Call data from the NZNPC telephone collection databases regarding human plant exposures between 2003 and 2010 were analysed retrospectively. The most common plants causing human poisoning were selected as the basis for this review. An extensive literature review was also performed by systematically searching OVID MEDLINE, ISI Web of Science, Scopus and Google Scholar. Further information was obtained from book chapters, relevant news reports and web material. Results For the years 2003–2010 inclusive, a total of 256,969 enquiries were received by the NZNPC. Of these enquiries, 11,049

  • Food Borne Diseases
    204 Food Science 19 Food Borne Diseases While food is necessary for sustaining life, it could also be a cause of illness. There is a general misconception that if a food is ‘natural’, it must be ‘safe’. Unfortunately the fact that many toxins occur in natural plant foods, falsifies this naïve view. Most of these endogenous toxins are in plant foods and a few in animal foods. Toxins from Plants Solanine of potatoes is one of the best known plant toxins. It is a steroid which occurs in potatoes and other members of solanaceae family (e.g., aubergine) and the highly poisonous nightshades. Normally potatoes contain 2–15 mg per 100 g (fresh weight). When potatoes are exposed to light and turn green, the level of solanine can be as high as 100 mg per 100 g. It is mostly concentrated under the skin. Potato sprouts may contain even higher amounts. Solanine can cause abdominal pain and diarrhoea, if injested in large amounts. Solanine is an inhibitor of the enzyme acetyl choline esterase, which is a key component of the nervous system. Ingestion of solanine have been reported to lead to signs of neurological damage. As there is a general public awareness of the health hazards of eating green potatoes, the incidence of potato poisoning is low. Solanine is not lost during normal cooking as it is insoluble in water and is heat stable. Caffeine is a purine alkaloid. Theobromine is another important member of this group. These occur in tea, coffee, cocoa and cola beverages, which are regarded as stimulants.

  • Potential Terrorist Use of Nicotine and Solanine Toxins - 09/05/2003
    For Health Professionals Health Alerts Health Advisory #48 - Potential Terrorist Use of Nicotine and Solanine Toxins - 09/05/2003 Over the past several years, various reports have described a growing terrorist interest in the use of two plant toxins as potential mass poisoning agents. These kinds of poisons have been associated with training for limited-scope attacks, such as assassination. These poisons, nicotine and solanine, are naturally occurring toxins obtained from tobacco and potatoes, respectively. References to nicotine and solanine appear in numerous terrorist training manuals and documents seized in Afghanistan. There are no known instances of actual use of either poison by Islamic terrorist organizations; however, nicotine was used in a recent domestic criminal poisoning incident, resulting in the sickening of nearly 100 people in Michigan. The acute toxicity of nicotine is well documented as a result of a number of accidental poisonings. While comparatively less toxic than cyanide, botulinium toxin or ricin, both substances can be lethal in high doses or if medical treatment is significantly delayed. Both toxins occur naturally in established agricultural products making their availability and ease of chemical separation the key attractions for terrorists. The most likely technique for nicotine or solanine poisoning would be food, beverage, or water contamination; however, nicotine can also be absorbed through the skin and mouth and the digestive and respiratory tracts. Terrorist manuals detail simple instructions on how to produce both nicotine and solanine poisons. Nicotine is widely available, inexpensive, and uncomplicated--it can be produced using a basic knowledge of chemistry. Nicotine is a fast-acting poison, absorbed through the digestive and respiratory tracts, as well as through the skin and mouth.

  • A High-Throughput Extraction and Analysis Method for Steroidal Glycoalkaloids in Tomato
    fpls-11-00767 June 19, 2020 Time: 15:23 # 1 METHODS published: 18 June 2020 doi: 10.3389/fpls.2020.00767 A High-Throughput Extraction and Analysis Method for Steroidal Glycoalkaloids in Tomato Michael P. Dzakovich1, Jordan L. Hartman1 and Jessica L. Cooperstone1,2* 1 Department of Horticulture and Crop Science, The Ohio State University, Columbus, OH, United States, 2 Department of Food Science and Technology, The Ohio State University, Columbus, OH, United States Tomato steroidal glycoalkaloids (tSGAs) are a class of cholesterol-derived metabolites uniquely produced by the tomato clade. These compounds provide protection against biotic stress due to their fungicidal and insecticidal properties. Although commonly reported as being anti-nutritional, both in vitro as well as pre-clinical animal studies have indicated that some tSGAs may have a beneficial impact on human health. However, the paucity of quantitative extraction and analysis methods presents a major obstacle for determining the biological and nutritional functions of tSGAs. To address Edited by: this problem, we developed and validated the first comprehensive extraction and Heiko Rischer, VTT Technical Research Centre ultra-high-performance liquid chromatography tandem mass spectrometry (UHPLC- of Finland Ltd., Finland MS/MS) quantification method for tSGAs.

  • Antioxidants in Potatoes: a Functional View on One of the Major Food Crops Worldwide
    molecules Review Antioxidants in Potatoes: A Functional View on One of the Major Food Crops Worldwide Hanjo Hellmann 1,* , Aymeric Goyer 2 and Duroy A. Navarre 3 1 School of Biological Sciences, Washington State University, Pullman, WA 99164, USA 2 Hermiston Agricultural Research and Extension Center, Department of Botany and Plant Pathology, Oregon State University, Hermiston, OR 97838, USA; [email protected] 3 USDA-ARS, Prosser, WA 99350, USA; [email protected] * Correspondence: [email protected] Abstract: With a growing world population, accelerating climate changes, and limited arable land, it is critical to focus on plant-based resources for sustainable food production. In addition, plants are a cornucopia for secondary metabolites, of which many have robust antioxidative capacities and are beneficial for human health. Potato is one of the major food crops worldwide, and is recognized by the United Nations as an excellent food source for an increasing world population. Potato tubers are rich in a plethora of antioxidants with an array of health-promoting effects. This review article provides a detailed overview about the biosynthesis, chemical and health-promoting properties of the most abundant antioxidants in potato tubers, including several vitamins, carotenoids and phenylpropanoids. The dietary contribution of diverse commercial and primitive cultivars are detailed and document that potato contributes much more than just complex carbohydrates to the diet. Finally, the review provides insights into the current and future potential of potato-based systems as tools and resources for healthy and sustainable food production.

Received: 27 March 2013; in revised form: 5 April 2013 / Accepted: 16 April 2013 / Published: 23 April 2013 Abstract: There is a need to develop food-compatible conditions to alter the structures of fungal, bacterial, and plant toxins, thus transforming toxins to nontoxic molecules. The term ‘chemical genetics’ has been used to describe this approach. This overview attempts to survey and consolidate the widely scattered literature on the inhibition by natural compounds and plant extracts of the biological (toxicological) activity of the following food-related toxins: aflatoxin B1, fumonisins, and ochratoxin A produced by fungi; cholera toxin produced by Vibrio cholerae bacteria; Shiga toxins produced by E. coli bacteria; staphylococcal enterotoxins produced by Staphylococcus aureus bacteria; ricin produced by seeds of the castor plant Ricinus communis; and the glycoalkaloid α-chaconine synthesized in potato tubers and leaves. The reduction of biological activity has been achieved by one or more of the following approaches: inhibition of the release of the toxin into the environment, especially food; an alteration of the structural integrity of the toxin molecules; changes in the optimum microenvironment, especially pH, for toxin activity; and protection against adverse effects of the toxins in cells, animals, and humans (chemoprevention).
