Millions of foodborne illness cases occur in China annually, causing significant social and economic burdens. Improper food handling has been observed not only among commercial food handlers but also among residential food handlers. It is critical to conduct a comprehensive scoping review of previous efforts to identify food safety knowledge gaps, explore the factors impacting knowledge levels, and synthesize the effectiveness of all types of food safety educational interventions for commercial and residential food handlers in China. This review aims to analyze food safety education studies published over the past 20 years and provide foundations for developing more effective food safety educational interventions in China. A total of 35 studies were included in this review. Most studies reported that Chinese commercial and residential food handlers had insufficient food safety knowledge, especially in the areas of foodborne pathogens and safe food-handling practices. The factors impacting food handlers’ knowledge levels included education level, gender, income level, residency (rural vs. urban), the use of WeMedia, college students’ major, and food safety training experiences. Food handlers in the following demographic groups tend to have lower levels of food safety knowledge: lower education levels, the elderly, males, lower-income levels, rural residents, those who do not use WeMedia, those without food safety training experience, or college students in nonbiology-focused majors. Many food handlers did not always follow recommended food safety practices, such as proper meat handling practices, handwashing practices, and cleaning and sanitation practices. Thirteen studies evaluated the effectiveness of educational interventions, and knowledge increases were reported after all interventions. The findings of this review provide guidance to researchers, educators, and government agencies in their future efforts to develop education programs emphasizing the importance of microbial food-safety content and behavior change regarding food safety and hygiene practices.
The Waterborne Disease Outbreak Investigation Toolkit is a guide to assist state and local health departments in conducting waterborne disease outbreak investigations. CDC developed this toolkit to help partners address the unique challenges they face when investigating waterborne disease outbreaks. Because of the numerous ways in which water impacts every person’s daily lives, timely detection, response, and control of these outbreaks is crucial to protect public health.
Using experiences of epidemiologists at the state and local levels, this toolkit describes best practices in preparing for, identifying, and remediating a waterborne disease outbreak.

Ice cubes are usually used to cooling drinks and foods during the summer and hot weather days in Taiwan. In order to continuously ensure the sanitation and safety of ice cube product for consumers, Taiwan Food and Drug Administration (TFDA) will initiate the 2021 Inspection Project for Ice Cube, and will be conducted with local government health bureaus to improve food safety and sanitation management.
The inspection items will focus on the registration requirements for food businesses, the Regulation on Good Hygiene Practice for Food (GHP), the product liability insurance, the self-management, the product traceability, the transport control, the food practitioner sanitation management. And the ice cube products will be checked of labeling and hygiene compliance. Violating provisions of the Act Governing Food Safety and Sanitation will be punished by law.
TFDA strongly recommends food businesses effectively implementing the self-management following the Act Governing Food Safety and Sanitation to ensure ice cubes safety and sanitation to protect the health of consumers.
Among the many consumers in Slovakia, smoothies are nowadays gaining popularity. Smoothie drinks are prepared from raw fruits and vegetables. Therefore, their microbiological safety depends on hygiene standards. The aim of this work was to monitor and quantify selected sensitive and antibiotic-resistant microorganisms present in collected smoothies. Twenty analyzed smoothie samples were collected from six food service establishments (fresh bars) in the capital city of Slovakia, Bratislava. Antibiotic-resistant bacteria were found in at least one of each fresh bar. Antibiotic-resistant coliform bacteria prevailed, especially in green smoothies or juices containing more vegetable ingredients. Resistance to ampicillin, ciprofloxacin, tetracycline, chloramphenicol, and gentamicin was observed in the case of coliform bacteria. More than half of the smoothie drink samples did not contain resistant enterococci. On the other hand, vancomycin-resistant enterococci were detected in 20% of samples. The most frequently isolated antibiotic-resistant strains belonged to the Enterobacter spp. or Klebsiella spp. genus. In the last part of the work, the pretreatment effect of smoothie components on the selected microorganisms’ counts in the final product was investigated. Washing ingredients with an aqueous solution of a biocide agent containing silver and hydrogen peroxide proved to be the most effective way to decrease bacterial counts. View Full-Text
South Korea’s drug safety agency said Thursday that the number of food poisoning cases in South Korea declined sharply last year, falling to about a half of the annual average for the previous five years, with the number of food poisoning patients more than halving.
The number of food poisoning cases occurring last year in the country stood at 178, which is equivalent to 52 percent of the annual average of 343 cases for the previous five years from 2015 to 2015, according to the Ministry of Food and Drug Safety.
Accordingly, the number of food poisoning patients also dropped to 2,747 last year, a level that is equivalent to 40 percent of the annual average of 6,874 for the previous five years.
The number of food poisoning patients per 1 million people stood at 139 in 2016, 109 in 2017, 222 in 2018, 79 in 2019 and 53 in 2020.
The numbers of both cases and patients marked the lowest the ministry has ever seen during the entire period that it has been collecting relevant data, since 2002.
The ministry attributed the decline in both food poisoning cases and patients to the sharp decrease in the number of group meal programs, including school meals, due to the outbreak of the coronavirus.
The number of farmers markets registered by the U. S. Department of Agriculture (USDA) has seen a significant increase, jumping from 1,755 in 1994 to 8,771 in 2019. Microbial studies have found evidence that produce sold at farmers can yield higher microbial counts than their retail counterparts; however, no previous literature explored the efficacy of microbial (bacteria and virus) persistence on a variety of different farmers market fomites over a 2-month period. The objectives of the current study were to conduct observations to determine the most commonly used food contact surface fomites at farmers markets and to investigate the persistence of key foodborne pathogens ( Escherichia coli O157:H7, Listeria monocytogenes, Salmonella spp., Staphylococcus aureus, and MS2 bacteriophage) on these fomites. A repeated-measures analysis of variance was used to compare the persistence rates of foodborne pathogens on cardboard, plastic, tablecloth, molded pulp fiber, and wicker baskets used to store, transport, and display produce at farmers markets. In general, molded pulp fiber, plastic and wicker surface materials supported the persistence of foodborne pathogens the most, with S. aureus demonstrating the highest log concentrations over the longest period of time. Additionally, Salmonella and E. coli strains also persisted for a significant period of time (approximately 32-days) on all fomites with the exception of tablecloth. The results suggest that foodborne pathogens on these fomites pose a high-risk of cross-contamination particularly if the fomites cannot be washed, rinsed, and sanitized effectively (e.g. cardboard). The results highlight the need avoid using porous, single-use storage containers such as cardboard, molded pulp fiber and wicker containers for extended periods of time and suggest the use of easily cleanable materials such as plastic containers.
A new study has shown that gentle streams of water carrying sound and microscopic air bubbles can clean bacteria from salad leaves more effectively than current washing methods used by suppliers and consumers. As well as reducing food poisoning, the findings could reduce food waste and have implications for the growing threat of anti-microbial resistance.
Salad and leafy green vegetables may be contaminated with harmful bacteria during growing, harvesting, preparation and retail leading to outbreaks of food poisoning which may be fatal in vulnerable groups.
Because there is no cooking process to reduce the microbial load in fresh salads, washing is vital by the supplier and the consumer.
Washing with soap, detergent bleach or other disinfectants is not recommended and the crevices in the leaf surface means washing with plain water may leave an infectious dose on the leaf. Even if chemicals are used, they may not penetrate the crevices.
In this new study, published in the journal Ultrasound in Medicine and Biology, scientists used acoustic water streams to clean spinach leaves directly sourced from the field crop, then compared the results with leaves rinsed in plain water at the same velocity.
Professor Timothy Leighton of the University of Southampton, who invented the technology and led this research, explains: “Our streams of water carry microscopic bubbles and acoustic waves down to the leaf. There the sound field sets up echoes at the surface of the leaves, and within the leaf crevices, that attract the bubbles towards the leaf and into the crevices. The sound field also causes the walls of the bubbles to ripple very quickly, turning each bubble into a microscopic ‘scrubbing’ machine. The rippling bubble wall causes strong currents to move in the water around the bubble, and sweep the microbes off the leaf. The bacteria, biofilms, and the bubbles themselves, are then rinsed off the leaf, leaving it clean and free of residues.”
The results showed that the microbial load on samples cleaned with the acoustic streams for two minutes was significantly lower six days after cleaning than on those treated without the added sound and bubbles. The acoustic cleaning also caused no further damage to the leaves and demonstrated the potential to extend food shelf life, which has important economic and sustainability implications.
Improving how food providers clean fresh produce could have a major role to play in combating the threat of anti-microbial resistance. In 2018 and 2019, there were fatal outbreaks of different strains of E. coli on romaine lettuce in the USA and Canada and samples from humans infected showed strains that are resistant to antibiotics.
University of Southampton PhD student Weng Yee (Beverly) Chong, who was part of the research team added: “I am very grateful to Vitacress and EPSRC for funding my PhD. I came from an engineering background, and took Professor Leighton’s classes, but he told me that I could be a trans-disciplinary PhD student, and become a microbiologist whilst increasingmy engineering skills. I am also very grateful to Sloan Water Technology Ltd.: They opened up their laboratories for use by students like me, so that I can keep working on my experiments. It is an exciting environment to work in because they are doing so much inventive work to combat the pandemic and infections as a whole.”
Previously as part of her PhD Beverly has studied how the technology could reduce the infection risk to horses and other livestock through hay cleaning.
The work was sponsored by Vitacress, whose Group Technical Director Helen Brierley said: “Ensuring food safety for our products is an essential requirement. At Vitacress, we wash our produce in natural spring water, and this type of ground-breaking new technology helps to enhance our process whilst ensuring our commitment to protect the environment is maintained. We are always interested in new developments and are excited to see the results of this research.”
