USA – FDA Releases Cyclospora Prevention, Response and Research Action Plan

FDA

Cyclospora_LifeCycle201

As part of our ongoing efforts to combat foodborne illness and aligned with our New Era of Smarter Food Safety initiative, today, the U.S. Food and Drug Administration released the Cyclospora Prevention, Response and Research Action Plan. Modeled after our Leafy Greens Shiga toxin-producing E. coli (STEC) Action Plan, the plan focuses on improving prevention, enhancing response activities and filling knowledge gaps in order to help prevent Cyclospora contamination of foods and to help prepare for responding to future outbreaks.

Cyclosporiasis is a foodborne intestinal illness caused by Cyclospora cayetanensis. The most common symptoms of cyclosporiasis are diarrhea, weight loss, nausea and fatigue. Cyclospora is historically associated with imported produce or travel outside the U.S.; however, we have also detected Cyclospora in domestically produced foods in recent years.

The FDA first documented Cyclospora in domestically grown produce (cilantro) in 2018 as part of an ongoing sampling assignment of fresh herbs. The testing was done as part of a surveillance sampling, and the cilantro sample was not linked to any illnesses or outbreaks. Not long after, domestically grown produce was again associated with an outbreak linked to a salad mix. During the FDA’s investigations into this outbreak, Cyclospora was also detected in an unused package of the salad containing domestically grown produce.

The availability of new testing methods for Cyclospora developed at the FDA’s Center for Food Safety and Applied Nutrition played an important role in helping the FDA identify these positive samples of Cyclospora in the cilantro and in the salad mix. The number of reported cases of this foodborne illness has been rising in recent years, in part because of better diagnostic and detection methods. According to the Centers for Disease Control and Prevention, there have been roughly 6,000 domestically acquired cases of Cyclospora over the last three years. The number of reported cases typically rises during the spring and summer, usually in May, June and July. Rising case numbers and the emergence of Cyclospora contamination in domestically grown produce prompted the FDA to create the Cyclospora Task Force in 2019. The task force is comprised of multidisciplinary experts across the FDA and CDC, with the goal of reducing the public health burden of foodborne illness caused by Cyclospora in produce.

The task force formulated the action plan announced today, which will serve as a strategic guide to improve prevention, enhance response activities and fill knowledge gaps about the presence of Cyclospora in or on foods. In the area of prevention, the new action plan highlights how we’re addressing this food safety issue through the development and delivery of prevention-focused education materials and outreach to stakeholders. We’re also working with industry to encourage the development of rapid test kits to specifically detect Cyclospora to better facilitate industry testing and root cause analysis activities. In addition, we plan to collaborate with industry to look for ways to more effectively control Cyclospora in the environment and on farms.

In the area of response, the plan is focused on expanding laboratory capacity across the FDA, state, foreign partners and academia to sample and test for Cyclospora, providing greater capacity to investigate during outbreak events. The FDA is also developing a new investigational tool to help guide assessments of farms potentially implicated in a Cyclospora outbreak to determine potential sources and routes of contamination.

Given the emerging nature of Cyclospora contamination in domestic produce, a large number of action items in this plan are aimed at addressing knowledge gaps. In this area, the FDA intends to work with CDC to better understand the case distribution of cyclosporiasis across the U.S. and to advance genotyping methods in clinical, food and environmental samples that will allow us to genetically link clinical cases to food products and environments identified by traceback during an outbreak. As part of this plan, the FDA also intends to work with industry and academia to better understand the prevalence of Cyclospora in agricultural water and to encourage data sharing to help stakeholders identify trends associated with Cyclospora contamination. Our action plan underscores the importance of collaboration across industry, academia, state, federal and foreign government partners, and other stakeholders to reduce the risks and public health burden caused by foodborne Cyclospora. We’ll continue updating this plan as actions are completed and new actions are identified.

While the U.S. has one of the safest food supplies in the world, we are focused on making it better. The FDA is focused on working with all stakeholders to achieve the goals identified in this Cyclospora Prevention, Response and Research action plan.

USA – Fresh Organic Basil Recalled Over Cyclospora Contamination Concerns

Consumer Reports

Cyclospora_LifeCycle201

Shenandoah Growers has recalled 3,240 units of fresh-cut, packaged organic basil because it may be contaminated with the parasite cyclospora.

The problem was found when a sample of the basil, which was imported from Columbia, was found to contain the parasite during a Food and Drug Administration routine test. No illnesses have been reported.

Research – Parasites in food an Invisible Threat

FAO

Foodborne parasitic diseases are often neglected in various food safety control systems, even though they can create severe human health problems. Because the production and monetary losses associated with them are often not visible, and the infected animals often show no signs, they are very difficult to detect. Different types of parasitic diseases can be transmitted to humans from pork, fish, freshwater crustaceans, vegetables, eggs of tapeworms and protozoa. The risks associated with all of them can, however, be avoided through the application of good hygiene, farming and fishing practices, and with the promotion of the community awareness. For example, the promotion of a participatory approach and the development of training packages for food businesses operators would be beneficial in raising awareness within the community. Basic information regarding the how the parasites are transmitted and their effects, and any and all preventive measure that each person can take should be included in communication topics. Food safety authorities can play an important part by using the guidance provided by Codex Alimentarius regarding animal production, food processing, and meat inspection. Furthermore, the development of networks of authorities committed to addressing the problem, would help prevent and control the spread of parasitic diseases.

Denmark – Disease outbreaks with rare microsporidia – Enterocytozoon bieneusi.

SSI

The Statens Serum Institut and the Danish Veterinary and Food Administration are currently investigating a disease outbreak in a company with a microorganism that has so far not been registered as a cause of disease outbreaks in Denmark. It is a species of microsporidia, Enterocytozoon bieneusi. It is believed that the infection occurred through food.

In October, a company in the metropolitan area reported more than 70 cases of diarrhea among their employees.

The Statens Serum Institut (SSI) has so far found samples from 11 people positive for Enterocytozoon bieneusi, which is a species of microsporidia. It is not a microorganism that we often detect in Denmark, and we have not previously seen disease outbreaks with it.

The infection can cause severe and prolonged diarrhea, abdominal pain and nausea. In addition, there may be symptoms such as fever, headache, muscle aches and fatigue (flu-like). The infection occurs from feces from infected people with poor hygiene to other people either directly or through food and drink.

“There are no registered persons outside the company who should have been infected with E. bieneus. But we urge the country’s physicians to pay attention to patients with prolonged diarrhea for no apparent reason. Especially if it is about immunocompromised people and with particularly long-lasting symptoms, ”says ward doctor Lasse Skafte Vestergaard, SSI. Read more about the disease outbreak with microsporidia  (EPI-NEWS – week 52a – 2020)

Microsporidia are protozoan parasites belonging to the phylum Microsporidia within which exist over 1000 species classified into approximately 100 genera. These eukaryotic obligate intracellular protozoans have been described infecting every major animal group, especially insects, fish, and mammals (Wittner 1999). Microsporidia have been increasingly recognized as opportunistic pathogens of immunodeficient patients (Weber et al. 1994), especially in Aids patients but it is also becoming increasingly common in immunocompetent individuals (Gainzarain et al. 1998, Lores et al. 2001).

Although during the last decade numerous data related to the epidemiology of this infection in humans and animals have been accumulated, implying a zoonotic nature of these parasites, direct evidence of transmission from animals to humans are still lacking (Deplazes et al. 2000).

Encephalitozoon cuniculi is probably the most extensively studied mammalian microsporidian and has been reported to infect a wide range of hosts, including common laboratory rodents as well as human and non-human primates. This is the first microsporidian species infecting humans that has been considered a zoonosis (Deplazes et al. 1996, Didier et al. 1996) .

The first identification of E. intestinalis in mammals other than humans was reported by Bornay et al. (1998) in the faeces of donkeys, dogs, pigs, cow, and goat suggesting that E. intestinalis might also be of zoonotic origin.

Enterocytozoon bieneusi is the most frequent microsporidian found in humans, especially in Aids patients. It has been associated mainly with chronic diarrhoea, although it has been diagnosed in patients with other forms of immunosuppression and in immunocompetent travellers with self-limited diarrhoea (Weber & Bryan 1994, Sobottka et al. 1995). In addition, this pathogen has recently been detected in other natural hosts such as pigs (Deplazes et al. 1996, Breitenmoser et al. 1999, Rinder et al. 2000), cows, goats, pigs, chickens, cats, turkeys (Bornay et al. 1998), rabbits, dogs (del Aguila et al. 1999), and in simian immunodeficiency virus-inoculated monkeys (Tzipori et al. 1997, Mansfield et al. 1997). Consequently, this microsporidian infection may be more common than previously suspected.
