Nobody really likes writing anything; this applies to professional writers as much if not more than to the rest of us who have to write to communicate, on top of our other responsibilities. Fortunately, there are some ways of making it a relatively painless process - and a good thing too, because writing the report is absolutely crucial to any investigation.
Progression of the Outbreak Investigation Outbreak Summary October 29, Final Case Count Update Reported cases of cyclosporiasis in the United States have returned to baseline levels; therefore, it is likely that the outbreaks identified during June—August have ended.
The number of reports of persons with illness increased beginning in June and returned to baseline in mid-to-late August, as shown in the epidemic curve epi curve.
A total of persons with cyclosporiasis were reported from 25 states and New York City: Illness onset dates ranged from June 1,to August 29, Ill persons ranged in age from less than 1 year to 94 years, with a median age of 52 years. This outbreak appears to be over. Investigations in Iowa and Nebraska On July 30,public health officials in the states of Iowa and Nebraska announced that their analysis indicated that restaurant-associated cases of cyclosporiasis in their states were linked to a salad mix.
According to FDA, a traceback investigation confirmed that the salad mix identified by Iowa and Nebraska was supplied to restaurants in those states by Taylor Farms de Mexico, a processor of foodservice salads.
The investigations were conducted at three Mexican-style restaurants and one grocery store location where multiple unrelated ill persons reported having eaten or shopped.
Ongoing Traceback Activities FDA is working with Mexican authorities to collect records to determine if there is a common farm or Preliminary investigation report area in Puebla, Mexico, that could have provided fresh cilantro to the three restaurants and the grocery store location associated with clusters of ill persons in Texas.
Conclusions The findings in the investigations suggest that there was more than one outbreak of cyclosporiasis during June—August in the United States. Some illnesses in Texas were linked to fresh cilantro from Puebla, Mexico.
As in and in years pastmost detected cases and outbreaks of cyclosporiasis in the United States have occurred Preliminary investigation report spring and summer months, and not all cases during the same time of year are necessarily caused by the same exposure.
For example, during a several-month period inthere were three separate and unrelated outbreaks of cyclosporiasis caused by different fresh produce items from various sources.
Strong evidence from epidemiologic investigations led to the recognition that the outbreaks were separate and unrelated. CDC and other institutions are working to develop advanced molecular detection methods for Cyclospora cayetanensis that could distinguish among strains of this parasite.
October Updates October 23, Investigation Update Reported cases of cyclosporiasis in the United States have returned to baseline levels; therefore, it is likely that the outbreaks identified during June—August have ended.
The number of reports of persons with illness increased beginning in June and returned to baseline in mid-to-late August. Investigations in Texas Epidemiologic and traceback investigations conducted by state and local public health and regulatory officials in Texas, the FDA, and CDC indicate that some illnesses among Texas residents were linked to fresh cilantro from Puebla, Mexico.
Investigating "clusters of illnesses" can provide critical clues about the source of an outbreak. A cluster of illnesses is defined as more than one unrelated ill person i. If several unrelated ill persons ate or shopped at the same location of a restaurant or store within several days of each other, it suggests that the contaminated food item was served or sold there.
In addition, traceback of suspected food items to identify a common point of contamination may be facilitated by records kept at these locations. Investigators identified more than 70 clusters of illnesses in Texas.
Most of the clusters identified in Texas involved two or three ill persons. Epidemiologic and traceback investigations were conducted at three restaurants and one grocery store location in Texas, where multiple unrelated ill persons reported having eaten or shopped.
Restaurant Cluster Investigations in Texas Thirty 30 ill persons reported eating at a single Mexican-style restaurant in Fort Bend County, Texas, in the 2—14 days before onset of illness.
Twenty-two 22 ill persons had laboratory-confirmed Cyclospora infection confirmed cases and 8 were probable case-patients case symptoms but no laboratory confirmation.
An analytic epidemiologic study was conducted that compared foods eaten at the restaurant by 25 of the persons who became ill versus 65 healthy persons who remained well. Ingredient-level analyses were conducted using meal consumption data and recipes. Four fresh produce ingredients were significantly associated with illness: Since these ingredients were served together in many different dishes, such as salsa, the statistical analysis could not definitively identify which of these ingredients was independently associated with illness.
However, fresh cilantro was the only ingredient consumed by all 25 ill persons in this study. In addition, salsa containing fresh raw uncooked cilantro was associated with illness, while salsa containing cooked cilantro was not.
Fresh cilantro was used in four types of restaurant-produced salsas. The three salsas that were not cooked were significantly associated with illness, whereas the one that was cooked before serving was not heat can kill Cyclospora.
Consumption of lettuce was not associated with illness in this analysis, and traceback information indicated that lettuce served in this restaurant was not from Taylor Farms de Mexico. Neither red cabbage nor carrots components of the Taylor Farms de Mexico salad mix linked with illness in Iowa and Nebraska were used in this restaurant.
Preliminary traceback information indicates that Puebla, Mexico, was a source of the fresh cilantro that was served to ill persons in this restaurant. Investigations were also conducted at two other Mexican-style restaurants in Central Texas. These restaurants were not related to the restaurant in Fort Bend County, not part of the same chain, and not part of a national restaurant chain.
A formal analytic epidemiologic study was not conducted among ill persons who had eaten at either location since these clusters had relatively few ill persons two confirmed and three probable cases who had eaten at one restaurant and two confirmed cases who had eaten at the second.Dec 02, · October 23, Investigation Update.
Reported cases of cyclosporiasis in the United States have returned to baseline levels; therefore, it is likely that the outbreaks identified during June–August have ended.
