The Potential for Acquiring Cryptosporidiosis

The Potential for Acquiring Cryptosporidiosis or Giardiosis From Consumption of Mung Bean Sprouts in Norway The potential for acquiring cryptosporidiosis or giardiosis from consumption of mung bean sprouts in Norway: a preliminary step-wise risk assessment. Int J Food Microbiol. 2005 Feb 15;98(3):291-300. Robertson LJ, Greig JD, Gjerde B, Fazil A. Parasitology Laboratory, Section of Microbiology, Immunology and Parasitology, Department of Food Safety and Infection Biology, The Norwegian School of Veterinary Science, PO boks 8146 Dep., N-0033 Oslo, Norway. The current work evolved from a microbial survey of fruits and vegetables conducted in Norway between 1999 and 2001. This survey found that mung bean sprouts were more likely to be contaminated with Cryptosporidium and Giardia than the other produce included in the survey. To support this observation and to demonstrate to public health officials that this might be a risk warranting further attention, a simple risk assessment was initiated. Assuming that 60,000 people in Norway consume a single serving of bean sprouts per week, and contamination levels are similar to

Microwave Microwave-Induced Stimulation of L-DOPA, Phenolics and Antioxidant Activity in Fava Bean (Vicia faba) for Parkinson's Diet Process Biochemistry Volume 39, Issue 11, 30 July 2004, Pages 1775-1784 Reena Randhir and Kalidas Shetty Chenoweth Laboratory, Department of Food Science, University of Massachusetts, Amherst, MA 01003, USA Fava bean sprouts are rich in levo-dihydroxy phenylalanine (L-DOPA), the precursor of dopamine, and are being investigated for use in the management of Parkinson's disease. The phytopharmaceutical value was improved during germination by a microwave treatment of the seeds, the phenolic content of the germinated sprouts increasing 700% and L-DOPA content by 59% compared to control. A higher antioxidant activity that was observed correlated with total phenolics and L-DOPA contents. The glucose-6-phosphate dehydrogenase activity peaked on the seventh day of germination with a concurrent increase in phenolics indicating enhanced mobilization of carbohydrates. A higher guaiacol peroxidase activity was observed indicating an increased polymerization of phenolics. The elevated superoxide dismutase activity was proportional to the stimulation of antioxidant activity. The major implication from this study is that microwave treatment can significantly stimulate


Contamination of Fresh Food Produce of Various Retail Types

Quantitative Assessment of Contamination of Fresh Food Produce of Various Retail Types by Human Quantitative assessment of contamination of fresh food produce of various retail types by human-virulent microsporidian spores. Appl Environ Microbiol. 2007 Jun;73(12):4071-3. Epub 2007 Apr 20. Jedrzejewski S, Graczyk TK, Slodkowicz-Kowalska A, Tamang L, Majewska AC. Department of Biology and Medical Parasitology, Poznan University of Medical Sciences, Poland. This study demonstrated that fresh food produce, such as berries, sprouts, and green-leafed vegetables, sold at the retail level can contain potentially viable microsporidian spores of human-virulent species, such as Enterocytozoon bieneusi, Encephalitozoon intestinalis, and Encephalitozoon cuniculi, at quantities representing a threat of food-borne infection.

Coliforms Coliforms are normally present on raw produce, and their presence does not necessarily signify that pathogens are present nor that the produce has come in contact with feces. The coliform group includes species from the genera Citrobacter, Klebsiella, Enterobacter, and E.coli. Other than E. coli, no foodborne outbreaks have been associated with coliforms. Coliforms were historically used as "indicator microorganisms" to serve as a measure of fecal contamination, and thus potentially of the presence of enteric pathogens. Although some coliforms are found in the intestinal tract of man, most are found throughout the environment and have little sanitary significance. In an effort to indicate 'quality' or 'safety' of such things as dairy products, drinking water, composted manure, and treated sewage, microbiologists developed the positive association of groups of bacteria to fecal contamination and dubbed this group of bacteria ''fecal coliform" . The term "thermotolerant coliforms" has recently been used to describe these organisms and is more appropriate.  These general terms for a large and diverse class of bacteria are useful and remain relevant


Industry Practices and Compliance with US Food

Industry Practices and Compliance with US Food and Drug Administration Guidelines Among California Sprout Firms Industry practices and compliance with U.S. Food and Drug Administration guidelines among California sprout firms. J Food Prot. 2003 Jul;66(7):1253-9. Thomas JL, Palumbo MS, Farrar JA, Farver TB, Cliver DO. California Department of Health Services, Food and Drug Branch, 601 North 7th Street, Sacramento, California 94234, USA. Since 1995, raw vegetable sprouts have been implicated as the vehicle of infection in 15 foodborne outbreaks involving Salmonella and 2 foodborne outbreaks involving Escherichia coli O157:H7. To reduce the numbers of sprout-related outbreaks, the U.S. Food and Drug Administration (FDA) published Guidance for Industry: Reducing Microbial Food Safety Hazards for Sprouting Seeds in 1999. Between October 2000 and April 2001, 61.5% (16 of 26) of the known commercial sprout firms in California were enrolled in a survey to evaluate the industry practices of California sprouting operations and to determine compliance with FDA guidelines. A standardized questionnaire was used to collect data on firm demographics and seed

Sprout De Hulling Equipment

Sprout De Hulling Equipment ISS Green Sprout Huller Once a seed is sprouted it sheds its coat (hull). Though the sprout is still quite alive, the dead seed hull begins to decayrather rapidly, bringing theproduct down with it.  The ISS Green Sprout Huller removes these seedcoats gently and accurately as the sprouts travel from one end and out theautomatic exit conveyor at the other end. We make a huller in any size to fit your needs.  Our most popular size removes hulls from 1000 lbs (400 kg) of sprouts per hour, depending on the type of sprout. Wealso build washing systems just for beansprouts and systems  that will do both bean and green sprouts.

Sulforaphane Inhibits 4

Sulforaphane Inhibits 4 Sulforaphane Inhibits 4-Aminobiphenyl-induced DNA Damage in Bladder Cells and Tissues. Carcinogenesis. 2010 Sep 1. Ding Y, Paonessa JD, Randall KL, Argoti D, Chen L, Vouros P, Zhang Y.Department of Cancer Prevention and Control, Roswell Park Cancer Institute, Buffalo, New York, 14263, USA.   Abstract Sulforaphane (SF) is a well known chemopreventive phytochemical and occurs in broccoli and to a lesser extent in other cruciferous vegetables, whereas 4-aminobiphenyl (ABP) is a major human bladder carcinogen and is present at significant levels in tobacco smoke. Here, we show that SF inhibits ABP-induced DNA damage in both human bladder cells in vitro and mouse bladder tissue in vivo, using dG-C8-ABP as a biomarker, which is the predominant ABP-DNA adduct formed in human bladder cells and tissues. SF activates Nrf2, which is a well-recognized chemopreventive target, and activates the Nrf2-regulated cytoprotective signaling pathway. Comparison between wild type mice and mice without Nrf2 shows that Nrf2 activation is required by SF for inhibition of ABP-induced DNA damage. Moreover, Nrf2 activation by SF

ISS Seed Screening Procedures

ISS Seed Screening Procedures ISS Seed Screening Procedures We have been asked by many, including the International Sprout Growers Association, to make our seed screening procedures available to other seed companies and sprout growers.  We are pleased to do so in the interest of food safety within the sprout industry. The seed is then screened for human pathogens in the following manner: Inspect Shipment.  Quarantine the seed and inspect the bags for evidence of contamination.  Such things would include mouse droppings, dead insect parts, holes in the bags that appear to have come from rodents or insects, etc.  In dim light, inspect the bags under black light for traces of urine. Record any findings. Sample Seed.  Sample 25 grams from of each and every bag in the entire shipment using a seed trier or other procedures described by the ISTA Handbook on Seed Sampling, Second Edition, January, 2004, International Seed Testing Association.  This is 1/1000th of the seed and often comes to 20-22 kg of seed.  If the composite sample
