To the Editor: Shiga toxin–producing Escherichia coli (STEC) cause severe illness in humans, peculiarly young and elderly persons. In previous decades, prevention and command measures focused on STEC O157:H7; still, in recent years, non-O157 STEC–related outbreaks and illnesses have been detected more than frequently. In the United States, vi serogroups (O26, O45, O103, O111, O121, and O145) account for ≈75% of the reported non-O157 STEC illnesses (1).
On August iv, 2010, the Maine Center for Affliction Control and Prevention (Maine CDC) investigated 2 isolates of nonmotile STEC O26 that were duplicate by pulsed-field gel electrophoresis (PFGE). Both case-patients had diarrhea and abdominal cramps, shopped at grocery stores in the aforementioned town, and reported consumption of ground beef. Instance-patient 1 purchased ground beef at Store A; a shopper carte used for the purchase was shared with investigators. Case-patient 2 consumed footing beef purchased from ii stores (Stores B and C); neither shopper cards nor receipts were bachelor.
On August 5, a Maine Section of Agriculture, Nutrient and Rural Resources (Maine DoA) inspector visited Stores A and B. On June 25, case-patient 1 had purchased 90% lean ground beef at Store A; the beef was produced by a parent company with multiple establishments. Inspectors cross-referenced this purchase with meat grinding logs from Store B, which revealed that the parent company that supplied ground beef to Store A also supplied beef to Store B. Maine DoA notified the United states Department of Agriculture, Food Safety and Inspection Service (USDA-FSIS), of a mutual manufacturer.
On August 9, the New York State (NYS) Department of Wellness contacted Maine CDC regarding a third case-patient with an STEC O26 isolate that was indistinguishable by PFGE from the other ii isolates. Case-patient 3 had handled ninety% lean ground beef purchased from the grocery store chain used by case-patient ane (Store A). Shopper card information indicated that the beefiness was purchased on June 17. Ground beef was the but mutual exposure among the 3 case-patients.
During Baronial 18–26, Maine DoA, NYS Section of Agronomics and Markets, and USDA-FSIS conducted a traceback of ground beefiness (Effigy). Traceback revealed that for >10 years, Store A had been purchasing 90% lean basis beef from Institution X (1 of many establishments within the parent company). Further investigation revealed that implicated ground beef from Store A locations in Maine and New York had come from the same lot at Establishment Ten. USDA-FSIS conducted ground beefiness traceback at Stores B and C; source materials were received from multiple establishments, merely Establishment 10 was the but common supplier (Figure). On August 28, Establishment 10 recalled ≈eight,500 pounds of ground beef that had been produced on June eleven.
Supplier traceback for ground beef associated with a cluster of Escherichia coli O26 infections in Maine (ME) and New York (NY), 2010.
On September two, the NYS Section of Wellness Public Health Laboratory tested leftover hamburger patties purchased by instance-patient 3. The samples were confirmed as STEC O26 with a PFGE pattern indistinguishable from the strains isolated from case-patients.
On Nov 17, USDA-FSIS completed an cess at Establishment X and determined that the visitor's food safety arrangement was adequate to control pathogens of business. Follow-up testing of beef trim samples at Establishment X were negative for STEC O26 and O157:H7.
The Council to Meliorate Foodborne Outbreak Response guidelines emphasize the importance of timely involvement of all members in outbreak investigations (2). A review of enteric affliction investigations by Hedberg et al. (iii) concluded a demand to increase timeliness of case investigation and to reduce delays during outbreak investigations. While waiting for PFGE confirmation, Maine CDC notified Maine DoA of case-patients who purchased basis beef in the same city. Within 48 hours, an inspector visited grocery stores where case-patients purchased footing beef and notified USDA-FSIS of the disease investigation. X days subsequently the shopper card information from instance-patient 3 was available, USDA-FSIS convened a recollect committee. Quick action by all agencies led to timely investigation, traceback, and recall. This well-characterized outbreak of simply 3 cases of STEC O26 infection led to a recall of ground beefiness.
Foodborne illness investigations increasingly rely on buy records from shopper cards, which record information such as purchase dates, brands, and production types that are valuable for traceback and identification of common exposure to a food item. After a thorough record review, investigators in this outbreak were able to narrow the purchased beef to 1 product appointment. This finding emphasizes the importance of recordkeeping at retail stores and meat processing establishments to determine product dates in the result of a call up. Shopper cards are used more than frequently during investigations, and then safeguards to protect the consumers' personally identifiable information are needed to prevent inappropriate disclosure and accidental breeches of confidentiality.
In an try to reduce human illnesses, USDA-FSIS developed policy on non-O157 STEC in raw beefiness products to declare half-dozen serogroups of pathogenic STEC as adulterants in nonintact raw beef (4). The Agency began implementing routine testing for these serogroups in June 2012.
