In mid-August, FDA and OSHA released a checklist to help food companies that were going through operational changes as a result of the COVID-19 pandemic. Specifically, the “Employee Health and Food Safety Checklist for Human and Animal Food Operations During the COVID-19 Pandemic” document reviews employee health and social distancing (how to deal with employee exposure and testing, the arrangement of work environments, especially considering work breaks and close operations), and food safety and HACCP plans—including suppliers and incoming ingredients—cGMPs, and other operational alterations due to COVID-19.
Today FDA held an “FDA COVID-19 Update for Food Operations Stakeholders” in collaboration with CDC and OSHA to further discuss the checklist, which targets owners, operators or agents in charge of a food operation. The purpose is to help the user assess operations during the COVID-19 pandemic, particularly operations that have restarted after a facility shutdown. Following the initial remarks, it was clear the FDA wanted to emphasize that the food safety checklist is intended to serve as a resource document, not a new guidance document or a new regulation. What was originally envisioned to be a one- to two-page checklist became a 16-page checklist that should be used in conjunction with additional information provided by FDA, CDC and OSHA, said Jenny Scott, senior advisor, office of food safety at CFSAN.
Scott reviewed the outline of the checklist, touching on employee health practices to help minimize the spread of COVID-19 (from basic handwashing practices to deadline with sick and exposed workers), employee testing and potential changes related to personnel requirements (i.e., if you are putting new people into new roles, you must consider whether more training is required), and the cGMP requirements. Among the key questions related to sanitation that Scott advised one must ask include: Are necessary cleaning, sanitizing and disinfecting supplies available? Are changes needed for cleaning, sanitizing and disinfecting procedures for certain areas or the frequency of conducting the procedures? Do the changes result in the need for updating instructions or training workers?
As the understanding of COVID-19 and how it spreads is evolving, Scott stressed that industry should frequently check FDA, CDC and OSHA websites for updates.
Michael Rogers, assistant commissioner for human and animal food operations, ORA, FDA also stressed the fact that the food safety checklist is not a new regulatory requirement, commenting that there has been “some anxiety associated” with this misperception. “This is simply an educational tool,” Rogers said. “We recognize that every firm is different, and the checklist should be information to consider…This is not an enforcement tool.” He added that the FDA’s approach during inspections will be collaborative and that the agency will not be holding firms to the specifics of the checklist. During the pandemic, the agency has been conducting mission critical inspections. FDA has also started domestic inspections in certain areas and will be preannouncing inspections as it moves forward, and it continues to assess the situation abroad to determine when foreign inspections can resume.
Vitamins play a critical role in the regulation of key physiological processes, such as blood clotting, metabolism and maintaining our vision. These biologically important compounds can be divided into two broad classes based on their solubility and differ in the way they are handled in the body—and in food safety laboratories. While excess amounts of water-soluble vitamins (including B1, B2, B3, B6 and B12) are excreted, fat-soluble vitamins (including vitamin A, D, E and K) can be stored in the liver or fatty tissue for later use. The simultaneous analysis of water- and fat-soluble vitamins in traditional liquid chromatography is difficult, and is compounded by the presence of biologically important vitamin isomers, which exist at lower concentrations and demand greater sensitivity from analytical techniques.
Food analysis laboratories support food manufacturers by assessing food safety and authenticity, and have a responsibility to produce precise and reliable data. Vitamins are among a number of compounds assessed in infant formulas, energy drinks and other supplements, and are added to fortify the nutritional value of these products. Given the critical nutritional role of vitamins, especially during early developmental periods, their characterization is highly important. This, along with the challenging and cumbersome nature of vitamin analysis, has spurred the development of innovative high-performance liquid chromatography (HPLC) methods for food safety testing.
Unique Challenges of Vitamin Analysis
The simultaneous analysis of water- and fat-soluble vitamins is difficult to achieve with reversed-phase high-performance liquid chromatography, due to the wide range of hydrophobicity among vitamins. Highly hydrophobic fat-soluble vitamins are retained strongly by chromatography columns and are only eluted with high-strength mobile phases. In contrast, water-soluble vitamins are usually poorly retained, even with very weak mobile phases. As the ideal conditions for chromatographic separation are very different for the two vitamin classes, there have been efforts to explore the possibility of operating two columns sequentially in one system. The early versions of this approach, however, were not well suited to high-throughput food safety laboratories, requiring complex hardware setup and even more complicated chromatography data system programming.
Prior to liquid chromatography analysis, food samples must be purified and concentrated to ensure target analytes can be detected without matrix interference. Liquid-liquid extraction is one purification method used to prepare for the analysis of vitamins and other compounds; it was one of the first methods developed for purification and enables compounds to be separated based on their relative solubilities in two different immiscible liquids.1 It is a simple, flexible and affordable method, yet has several major disadvantages.2 Liquid-liquid extraction consists of multiple tedious steps and requires the use of large volumes, therefore the time for completion is highly dependent on the operator’s skills and experience. Consequently, the duration of sample exposure to unfavorable conditions can vary greatly, which compromises reproducibility and efficiency of the method. This is of concern for vitamins that are particularly prone to degradation and loss when exposed to heat and light, such as vitamin D in milk powder.
Two-Dimensional Liquid Chromatography Enables Deeper and Faster Analysis
Analysts in the food industry are under pressure to process high volumes of samples, and require simple, high-throughput and high-resolution systems. Fortunately, two-dimensional liquid chromatography (2D-LC) systems have evolved markedly in recent years, and are ideally suited for the separation of vitamins and other compounds in food and beverages. There are two main types of systems, known as comprehensive and heart-cutting 2D-LC. In comprehensive 2D-LC, the sample is separated on the first column, as it would be in 1D-LC. The entire eluate is then passed in distinct portions into a second column with a different selectivity, enabling improved separation of closely eluting compounds. In contrast, heart-cutting 2D-LC is more suited to targeted studies as only a selected fraction (heart-cut) of the eluate is transferred to the second-dimension column.
Recently, another novel approach has emerged which utilizes two independent LC flow paths. In dual workflows, each sample is processed by two columns in parallel, which are integrated in a single instrument for ease of use. The columns may offer identical or different analyses to enable a higher throughput or deeper insights on each sample. This approach is highly suited to vitamin analysis, as the two reversed-phase columns enable simultaneous analysis of water- and fat-soluble vitamins. A simple, optimized preparation method is required for each of the two vitamin classes to ensure samples are appropriately filtered and concentrated or diluted, depending on the expected amount of analyte in the sample. The dual approach enables a broad range of ingredients to be assessed concurrently in supplement tablets, energy drinks, and other food and beverages containing both water- and fat-soluble vitamins. For analysts working to validate claims by food vendors, these advances are a welcome change.
Refined Detection and Extraction Methods Create a Boost in Productivity
Analysts in food analysis laboratories now have a better ability to detect a wide range of components in less time, due to improved detection and extraction methods. Modern LC systems utilize a wide range of analytical detectors, including:
Mass spectrometry (MS)
Diode array detection (DAD)
Multi-wavelength detection
Charged aerosol detection (CAD)
Fluorescence detection (FLD)
The optimal detector technology will depend on the molecular characteristics of the target analyte. Infant formula, for example, can be analyzed by DAD and FLD, with detection and separation powerful enough to accurately quantify the four isomers of vitamin E, and separate vitamin D2 and D3. Highly sensitive 2D-LC methods are also particularly favorable for the trace level quantitation of toxins in food, such as aflatoxins in nuts, grains and spices.
Given the limitations of liquid-liquid extraction, an alternative, simplified approach has been sought for 2D-LC analysis. Liquid-liquid extraction, prior to chromatography analysis, involves many tedious separation steps. In contrast, the use of solid phase extraction for infant formula testing reduces pre-treatment time from three hours to one hour, while improving detection. This is of great significance in the context of enterprise product quality control, where a faster, simpler pre-treatment method translates into a greater capacity of product testing and evaluation.
HPLC Toolkit for Food Safety Analysis Continues to Expand
Several other HPLC approaches have also been utilized in the field of food safety and authentication. For example, ultra-high-performance liquid chromatography (UHPLC) with detection by CAD followed by principal component analysis (PCA) can be used to investigate olive oil purity. In contrast to conventional approaches (fatty acid and sterol analysis), this revised method requires very little time and laboratory resources to complete, enabling companies to significantly reduce costs by implementing in-house purity analysis. With a reduced need for chemicals and solvents compared with fatty acid and sterol analyses, UHPLC-CAD provides a more environmentally friendly alternative.
Analyzing amino acid content in wine is an important aspect of quality control yet requiring derivatization to improve retention and separation of highly hydrophilic amino acids. Derivatization, however, is labor-intensive, error-prone, and involves the handling of toxic chemicals. To overcome these limitations, hydrophilic interaction liquid chromatography (HILIC) combined with mass detection has been identified as an alternative method. While HILIC is an effective technique for the separation of small polar compounds on polar stationary phases, there still may be cases where analytes in complex samples will not be completely separated. The combination of HILIC with MS detection overcomes this challenge, as MS provides another level of selectivity. Modern single quadrupole mass detectors are easy to operate and control, so even users without in-depth MS expertise can enjoy improved accuracy and reproducibility, while skipping derivatization steps.
Conclusion
Recent innovations in 2D- and dual LC technology are well suited to routine vitamin analysis, and the assessment of other components important in food safety evaluation. The concurrent and precise assessment of water- and fat-soluble vitamins, despite their markedly different retention and elution characteristics, is a major step forward for the industry. Drastic improvements in 2D-LC usability, flexibility and sensitivity also allows for biologically important vitamin isomers to be detected at trace levels. A shift towards simpler, high-throughput systems that eliminate complicated assembly processes, derivatization and liquid-liquid extraction saves time and money, while enabling laboratories to produce more reliable results for food manufacturers. In terms of time and solvent savings, solid phase extraction is superior to liquid-liquid extraction and is one of many welcome additions to the food analysis toolkit.

The 2020 Food Safety Consortium Virtual Conference Series will discuss COVID-19 Lessons Learned and Worker Safety | The Event runs September 3 through December 17 | Register NowA poultry processing plant operated by Foster Farms must shut down per the Merced County Department of Public Health (California) as a result of a large COVID-19 outbreak that has resulted in the death of eight employees. At least 358 workers at the facility located in Livingston, California have tested positive for COVID-19 (an outbreak was officially declared on June 29). Several buildings make up the Livingston facility, which employs about 2600 workers.
“In view of increasing deaths and uncontrolled COVID-19 cases, the decision was made to order the Livingston Plant within the Foster Farms Livingston Complex closed until acceptable safety measures are in place,” said Dr. Salvador Sandoval, Merced County’s Public Health Officer. In addition, the Los Angeles Times reports that officials are concerned the outbreak could be worse than reported because universal worker testing has not been completed.
The plant will reportedly close until September 7. During the closure, the facility will be deep cleaned and employees will engage in a new round of testing. Merced County states that an employee cannot return to work until he or she receives two negative COVID-19 test results within seven days.

Due to health benefits, grape seed extract has become more and more popular. Cheaper plant extracts, for example peanut skin extract, show very similar results with chromatographic methods, and therefore adulteration of grape seed extract may remain undetected. The American Botanical Council’s Botanical Adulterants Prevention Program released a laboratory guidance document that reviews analytical methods for detecting adulteration of grape seed extract with proanthocyanidin-rich extracts from other botanical sources.
This month I had the pleasure of interviewing Neshat Soofi, president of JIT Experts Hive, for the Women in Food Safety Column. She shared some of her inspirational experiences working with multicultural teams and companies, and how she eventually became an entrepreneur, launching her own business. “As food safety experts, our primary job is to minimize the risk of contamination in food and protect consumer health and safety. Of course, there are other aspects of our job such as contributing to the profitable growth of companies we work for. Sometimes we get caught in conflict situations with a lot of pressure on us. Most of the time it comes down to assessing risk in uncertain situations and with limited information. Even food safety situations are not black and white. To make the right decision we need to assess the risk-taking multiple factors into consideration. One thing that always helped me was to remember why I was hired and that my reason for being in a company was to minimize risk to the consumers,” says Soofi. “Being a food safety professional also helped me understand business holistically, since as a food safety lead you have to work with many functions in a company, from sourcing to customer service, marketing and sales. As part of my career path, I even worked in different functions that provided me with different perspectives of business. This knowledge helped me be a better product safety and quality leader, and later helped me set up my own business, which provides consultation and expert knowledge in many areas of business.”
Join Women in Food Safety for a special episode on November 5 about career development and mentorship during the 2020 Food Safety Virtual Conference SeriesSoofi was born and raised in Iran and has lived in Canada and the United States for the past 30 years. She has more than 25 years of experience in product safety, quality and development working for small to large companies like Target, Cargill and Multifoods (Pillsbury). After working with some of the largest corporations, she decided to join start-up company “Brandless” to build their product safety, quality and integrity programs from scratch. After three years working in a fast-paced, autonomous environment, she started her own business called JIT Experts Hive. She leveraged her broad and diverse background to fill a gap in the market, connecting like-minded and purpose-driven hands-on experts to companies in need of those expertise in a just in time fashion. Connecting knowledge to innovation. The mission of JIT Experts Hive is to help accelerate the growth of CPG companies in food, supplement, CBD, cosmetic/beauty and household industries by providing just-in-time expertise.
Working in consumer-packaged goods (CPG) industries including food for more than 25 years, Soofi felt fortunate with what she has learned over the years. “I learned that in order to grow and succeed, I needed to step outside my comfort zone. Every job I took was very different from the previous one. Even going so far as stepping completely out of food safety and working in other areas of business like leading data governance and business intelligence, or getting into new product categories such as personal care, cosmetics and even household cleaners. What I found was that these learnings and experiences made me a better product safety and quality expert and leader. Product safety jobs are quite unique; one is responsible for results of work of many functions with no direct control over them. The ability to understand other functions, their priorities and pressures and look at situations through different lenses helps one assess the risks better and come up with better solutions. One can also articulate the risks and benefits in a way that would be more compelling and effective,” Soofi explained.
Neshat Soofi, president of JIT Experts Hive
With a unique multicultural background and experience working in large corporations leading teams in different countries, Soofi advises that when working with multicultural teams one should: Learn about each country’s work ethics, how to address someone (i.e., first name or with titles), what is the appropriate way of greeting and interacting during and after work hours, and the level and importance of hierarchy.
Tactical details are also important: Be cognizant of time zone differences and schedule meetings on a rotating time zone basis; in virtual meetings/calls and in the absence of getting the non-verbal cues and body language, pay more attention to pauses, silence and the importance of clear communication so things are not lost in translation or misinterpreted.
Last but not least, remember: Never assume, and never stereotype. Each person is unique and may be very different from the stereotype in their countries, so don’t go with assumptions. And if in doubt, ask, because it not only helps you understand their preference, but also helps break the ice.
As a female leader, Soofi has also learned a lot from her multicultural female team members. “As Cheryl Sandberg has mentioned in her book ‘Lean In’, women generally have a harder time taking a seat at the table! In some cultures this feeling is even stronger due to cultural factors. What I found for myself and many great talents in my teams was that gradually pushing ourselves out of comfort zones by taking challenging assignments, leading projects and teams and being the voice and face of the team was a great way to build confidence in yourself and take your rightful seat at the table. Don’t be afraid of failure and do not internalize it if it happens. Having a mentor to help you in this journey by providing advice but also constructive criticism and course correction when needed is key to success,” Soofi says.
Another aspect is that as a woman, building strong negotiation skills is a must. “Whether negotiating for a new position, salary, etc., do your homework, know where the bottom line and the absolute non-negotiable variable are for you, but also understand where you can compromise. At the same time, do not be afraid of hearing “no” and do not take things personally.”
Laura Gutierrez Becerra: What would be your number one piece of advice to young women professionals who are planning to be leaders in food safety?
Neshat Soofi: Don’t be shy! Reach out to experienced professionals in the industry; there are plenty of higher-level peers who will be willing to help you. A good mentor is priceless. I have a personal story to share: About four years ago, I got a message through LinkedIn from someone who has just moved to the US. I had not met her before, and she asked me if we could meet and talk about the food industry and jobs in the US. We met and I happily shared my experience and advice in seeking jobs, helped her with a mock interview and resume, and anything else I could. Four years later, she is a quality assurance manager in one of the largest food companies here in the United States. We have stayed great friends, and I am so proud of her resilience and success.
Gutierrez Becerra: Is there an unforgettable story during your career journey that still has an impact?
Soofi: When I was working in Canada in food manufacturing, I was called to the processing line one day regarding a potential foreign object issue. I stopped the line to find out the root cause. At the same time there was a lot of pressure to resume production since this was an order for a major account. Under pressure, I agreed to start the line with adding inspection and controls that I knew in my guts were not sufficient. The products were shipped, and we started to get a series of complaints about foreign objects in the product. Thank god there was no injury, but as you can imagine, that major account was not happy with the situation and we lost the business with them. It was a major loss and my boss from the head office came for a visit to our plant. I tried to explain why I had allowed the production to resume and release the product because we couldn’t have a late shipment. In response he asked me one question, “What’s your job title?” I responded, “I am the food safety and quality assurance manager.” His comment was, “I am glad you remember. Your first priority is minimizing risk to consumers and company reputation. I am sure you took that into consideration when you okayed the release, [but] if not, please remember in future”. I expected him to be angry and was even prepared to be fired, but his quiet answer was more impactful. This is a lesson I remember to this day—there are rarely black and white situations in life, even in food safety. The key is to assess the risk and not let outside pressures impact your assessment and decisions.
Gutierrez Becerra: What do you hope to see in the next three to five years in terms of development and mentoring women in the industry?
Soofi: I see a need for networks like yours to connect new industry professionals regardless of gender to the more veteran experts on an as-needed basis—almost like a hotline, where food safety professionals can ask for advice and mentoring in a confidential and safe environment. This is becoming easier in a post-COVID era where virtual connections are becoming more of a norm than exception, and people from all over the world are learning to connect in ways that were not easy and personally comfortable in the past.
I also want to see a better appreciation of the importance of food safety programs in organizations, especially at leadership levels. We need to better articulate what additional values (efficiencies, better cultures, productivity, etc.) a great food safety program brings to the organization. I want food safety functions to be at the leadership tables and part of developing company strategies and directions. We can’t be only remembered when bad things happen and in the middle of a crisis. Food safety and quality leaders should be at the forefront of organizational leadership, all the way to the C-suite.

Turkish delight, baklava, halva, biscotti, mortadella, ice cream and many more delicious foods from around the world contain pistachios, which are pricey and therefore a popular target for food fraud. A recent article describes a method to detect spinach and green peas that often are used as a pistachio replacement due to their color and low price. The technique combines NIR (near infrared) spectroscopy and chemometric analysis and provides a method that is precise, fast and non-destructive.
During the production process, physical hazards can contaminate food products, making them unfit for human consumption. According to the USDA’s Food Safety and Inspection Service (FSIS), the leading cause of food recalls is foreign material contamination. This includes 20 of the top 50, and three of the top five, largest food recalls issued in 2019.
As methods for detecting foreign materials in food have improved over time, you might think that associated recalls should be declining. To the contrary, USDA FSIS and FDA recalls due to foreign material seem to be increasing. During the entire calendar year of 2018, 28 of the 382 food recalls (7.3%) in the USDA’s recall case archive were for foreign material contamination. Through 2019, this figure increased to approximately 50 of the 337 food recalls (14.8%). Each of these recalls may have had a significant negative impact on those brands and their customers, which makes foreign material detection a crucial component of any food safety system.
The FDA notes, “hard or sharp foreign materials found in food may cause traumatic injury, including laceration and perforation of tissues of the mouth, tongue, throat, stomach and intestine, as well as damage to the teeth and gums”. Metal, plastic and glass are by far the most common types of foreign materials. There are many ways foreign materials can be introduced into a product, including raw materials, employee error, maintenance and cleaning procedures, and equipment malfunction or breakage during the manufacturing and packaging processes.
The increasing use of automation and machinery to perform tasks that were once done by hand are likely driving increases in foreign matter contamination. In addition, improved manufacturer capabilities to detect particles in food could be triggering these recalls, as most of the recalls have been voluntary by the manufacturer.
To prevent foreign material recalls, it is key to first prevent foreign materials in food production facilities. A proper food safety/ HACCP plan should be introduced to prevent these contaminants from ending up in the finished food product through prevention, detection and investigation.
Food manufacturers also have a variety of options when it comes to the detection of foreign objects from entering food on production lines. In addition to metal detectors, x-ray systems, optical sorting and camera-based systems, novel methods such as infrared multi-wavelength imaging and nuclear magnetic resonance are in development to resolve the problem of detection of similar foreign materials in a complex background. Such systems are commonly identified as CCPs (Critical Control Points)/preventive controls within our food safety plans.
But what factors should you focus on when deciding between different inspection systems? Product type, flow characteristics, particle size, density and blended components are important factors in foreign material detection. Typically, food manufacturers use metal and/or x-ray inspection for foreign material detection in food production as their CCP/preventive control. While both technologies are commonly used, there are reasons why x-ray inspection is becoming more popular. Foreign objects can vary in size and material, so a detection method like an x-ray that is based on density often provides the best performance.
Regardless of which detection system you choose, keep in mind that FSMA gives FDA the power to scientifically evaluate food safety programs and preventive controls implemented in a food production facility, so validation and verification are crucial elements of any detection system.
It is also important to remember that a key element of any validation system is the equipment validation process. This process ensures that your equipment operates properly and is appropriate for its intended use. This process consists of three steps: Installation qualification, operational qualification and performance qualification.
Installation qualification is the first step of the equipment validation process, designed to ensure that the instrument is properly installed, in a suitable environment free from interference. This process takes into consideration the necessary electrical requirements such as voltage and frequency ratings, as well as other factors related with the environment, such as temperature and humidity. These requirements are generally established by the manufacturer and can be found within the installation manual.
The second step is operational qualification. This ensures that the equipment will operate according to its technical specification. In order to achieve this, the general functions of the equipment must be tested within the specified range limits. Therefore, this step focuses on the overall functionality of the instrument.
The third and last step is the performance qualification, which is focused on providing documented evidence through specific tests that the instrument will performs according to the routine specifications. These requirements could be established by internal and industry standards.
Following these three steps will allow you to provide documented evidence that the equipment will perform adequately within the work environment and for the intended process. After completion of the equipment validation process, monitoring and verification procedures must be established to guarantee the correct operation of the instrument, as well procedures to address deviations and recordkeeping. This will help you effectively control the hazards identified within our operation.
There can be massive consequences if products contaminated with foreign material are purchased and consumed by the public. That’s why the development and implementation of a strong food safety/ HACCP plan, coupled with the selection and validation of your detection equipment, are so important. These steps are each key elements in protecting your customers and your brand.
As a precautionary measure, ALDI is voluntarily recalling assorted peaches received from its supplier, Wawona Packing Company, due to possible Salmonella contamination.
–UPDATE AUGUST 31, 2020 — Prima Wawona has recalled bagged, bulk and loose peaches that were distributed nationwide to retailers that include ALDI, Food Lion, Hannaford, Kroger, Target, Walmart and Wegmans. As of August 28, the CDC reported the outbreak of Salmonella infections reached 78 cases across 12 states.
In addition, the recall of Prima Wawona peaches has extended to Canada, Singapore and New Zealand. FDA states that the products may have been shipped to Australia, Canada, China, Costa Rica, Ecuador, El Salvador, Guatamala, Honduras, Mexico, Panama, the Philippines, Singapore, Taiwan and the United Arab Emirates.
–END UPDATE–
Do not eat, sell or serve Wawona-brand bagged peaches from ALDI stores, says the FDA. ALDI issued a voluntary recall of two-pound clear plastic bags of peaches from Wawona Packing Company, LLC following a multistate outbreak of Salmonella Enteritidis that has been linked to the product. The peaches were sold in ALDI stores from June 1 until present, and as of August 19, the CDC reported 68 cases of Salmonella infections across nine states, with 14 hospitalizations. No deaths have been reported
“FDA’s traceback investigation is ongoing to identify the source of this outbreak and to determine if potentially contaminated product has been shipped to additional retailers,” the agency stated in an investigation update.
Learn more about food safety supply chain management & traceability during the 2020 Food Safety Consortium Virtual Conference SeriesThe FDA and CDC have been investigating a multistate outbreak ofCyclospora involving bagged salads from Fresh Express since June. Although the products were recalled and should no longer be available in retail locations, the CDC continues to report more cases. As of August 12, 2020, the CDC counted 690 people with laboratory-confirmed Cyclospora infections throughout 13 states. Thirty-seven people have been hospitalized, and no deaths have been reported.
As the FDA conducted its traceback investigation to find the source of the outbreak linked to the Fresh Express products, the agency was able to identify several farms. It analyzed water samples from two public access points along a regional water management canal (C-23) west of Port St. Lucie, Florida. Using the FDA’s validated testing method, the samples tested positive for Cyclospora cayetanensis. However, it is important to note that the Cyclospora found might not be a direct match to the pathogen found in the clinical cases.
According to FDA: “Given the emerging nature of genetic typing methodologies for this parasite, the FDA has been unable to determine if the Cyclospora detected in the canal is a genetic match to the clinical cases, therefore, there is currently not enough evidence to conclusively determine the cause of this outbreak. Nevertheless, the current state of the investigation helps advance what we know about Cyclospora and offers important clues to inform future preventive measures.”
The agency’s traceback investigation is complete, but the cause or source of the outbreak has not been determined. The investigation also revealed that carrots are no longer of interest at as part of the outbreak, but red cabbage and iceberg lettuce are still being investigated. FDA is also working with Florida and the area’s local water district to learn more about the source of Cyclospora in the canal.
