Surveillance & Analysis on E. coli News & Outbreaks

Adams Farm Slaughterhouse E. coli Outbreak Over

Eleven people infected with the outbreak strain of STEC O157:H7 were reported from five states. A list of the states and the number of cases in each can be found on the Case Count Map page.

Illnesses started on dates ranging from June 27, 2016 to September 10, 2016. Ill people ranged in age from 1 year to 74, with a median age of 32. Forty-five percent of ill people were female. Seven ill people were hospitalized. One ill person developed hemolytic uremic syndrome, a type of kidney failure, and no deaths were reported.

Epidemiologic, traceback, and laboratory evidence indicated that beef products produced by Adams Farm Slaughterhouse in Athol, Massachusetts, were the likely source of this outbreak.

In interviews, ill people answered questions about the foods they ate and other exposures in the week before they became ill. Seven (100%) of the seven people reached for interview reported eating ground beef in the week before they became ill. Traceback information indicated that six (86%) of these seven ill people ate ground beef produced by Adams Farm Slaughterhouse.

The Connecticut Department of Public Health collected leftover Adams Farm Slaughterhouse ground beef from an ill person’s home and from a restaurant for testing. Test results showed the outbreak strain of STEC O157:H7 in both samples of leftover ground beef.

On September 24, 2016, Adams Farm Slaughterhouse recalled various cuts of beef, veal, and bison products due to possible E. coli O157:H7 contamination. The products originated from animals slaughtered on July 15, 25, and 27, 2016 and August 3, 8, 10, 11, 17, 24, and 26, 2016, and further processed and packed on various dates between July 21 and September 22, 2016. These items were shipped to farmers’ markets, retail locations, and restaurants in Massachusetts, Connecticut, and eastern New York. The products may have been shipped to neighboring states. The products subject to recall have establishment number EST. 5497 inside the USDA mark of inspection and include several lot numbers and cuts of meat. The full list can be found on the USDA-FSIS website.

This outbreak appears to be over. However, the recalled beef, veal, and bison products may still be in freezers. Consumers who don’t know about the outbreak could continue to eat recalled products and get sick.

Sliver Springs E. coli Recall Expands.

Silver Springs Farms, Inc., a Harleysville, Pa. establishment is recalling approximately 7,970 pounds of ground beef and burger products, as well as an undetermined amount of sandwich steak products that may be adulterated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

The problem was discovered during a routine verification sampling performed by Silver Springs Farms, Inc. There have been no confirmed reports of illness or adverse reactions due to consumption of these products.

E. coli O157:H7 is a potentially deadly bacterium that can cause dehydration, bloody diarrhea and abdominal cramps 2–8 days (3–4 days, on average) after exposure the organism. While most people recover within a week, some develop a type of kidney failure called hemolytic uremic syndrome (HUS). This condition can occur among persons of any age but is most common in children under 5-years old and older adults. It is marked by easy bruising, pallor, and decreased urine output. Persons who experience these symptoms should seek emergency medical care immediately.

FSIS and the company are concerned that some product may be frozen and in consumers’ freezers.

Consumers who have purchased these products are urged not to consume them.

FSIS was notified of an investigation of E. coli O157:H7 illnesses on September 16, 2016. Working in conjunction with the Connecticut Department of Public Health, the Massachusetts Department of Public Health, and the Centers for Disease Control and Prevention, FSIS determined that there is a link between beef from Adams Farm Slaughterhouse and this illness cluster. Based on the epidemiological investigation, 7 case-patients have been identified in Connecticut, Massachusetts, Pennsylvania, and West Virginia with illness onset dates ranging from June 27, 2016 to September 4, 2016. Traceback information was available for 5 case-patients and indicated that all 5 case-patients consumed beef products supplied by Adams Farms Slaughterhouse. FSIS continues to work with public health partners on this investigation and will provide updated information as it becomes available.

E. coli O157:H7 is a potentially deadly bacterium that can cause dehydration, bloody diarrhea and abdominal cramps 2–8 days (3–4 days, on average) after exposure the organism. While most people recover within a week, some develop a type of kidney failure called hemolytic uremic syndrome (HUS). This condition can occur among persons of any age but is most common in children under 5-years old and older adults. It is marked by easy bruising, pallor, and decreased urine output. Persons who experience these symptoms should seek emergency medical care immediately.

Finding E. coli at Memo’s

KOMO TV 4 reports that public health officials say they are investigating two cases of E. coli associated with Memo’s Mexican Food in the University District.

One person, a King County resident, ate there on Aug. 18 and Aug. 24. The other, who isn’t from King County, ate there Aug. 24. Health officials first got reports of illness on Aug. 31.

Testing show both persons had the same strain of bacteria. The strain hadn’t been seen in King County before.

The strain is different from the cluster that recently affected several customers of the Matador restaurant in Ballard. The two clusters do not appear to be related, King County Public Health said.

“Our environmental health team performed a field investigation of the restaurant on 9/12/16 and identified factors that may have contributed to this foodborne illness outbreak, including improper cooling, cold holding, reheating of potentially hazardous food and the potential for cross contamination. Inspectors will return to the restaurant within 14 days to ensure continued compliance with the corrective measures that were put in place. The restaurant is working cooperatively with Public Health.”

Persons who have eaten at Memo’s and developed diarrhea within 10 days and anyone who develops bloody diarrhea should consult with their healthcare provider to determine if testing is necessary.

E. coli in Seattle

Seattle King County Public Health is investigating a cluster of five E. coli infections caused by Shiga-toxin producing E. coli (also called STEC) associated with Matador restaurant in Ballard. Four people ate on 8/14 and one person ate on 8/22. Public Health received the first report of illness on 8/22/16 and the most recent case was reported on 9/6/16.  All the people developed symptoms including diarrhea and abdominal cramps. Four people developed bloody diarrhea. Three people had been hospitalized with one person developing a type of kidney injury called hemolytic uremic syndrome (HUS). All five people have recovered.

Laboratory testing (molecular fingerprinting) has determined that all five people have the same strain of STEC bacteria.  Our investigation is in progress but due to food processing equipment cleaning and the possibility of cross contamination that were observed during an inspection by our Environmental Health team, Public Health has temporarily suspended Matador’s food business permit to allow time for thorough cleaning and sanitizing. The restaurant is working cooperatively with Public Health.

Persons who have eaten at Matador and developed diarrhea within 10 days and anyone who develops bloody diarrhea should consult with their healthcare provider to determine if testing is necessary.

Raw Milk Tied to E. coli Illnesses in Children

Due to two recent cases of young children being infected with E. coli, state health officials are reminding Michigan residents of the potential health risks associated with consuming unpasteurized milk or unpasteurized milk products, commonly referred to as raw milk or raw milk products.

The two E. coli O157:H7 cases, which were reported in Oakland and Wayne counties, both involve children who consumed unpasteurized or raw milk prior to their illnesses. Raw milk has been known to be a source of E. coli. The Michigan Department of Health and Human Services and local health departments are advising people not to consume unpasteurized milk or milk products made from unpasteurized milk.

Raw milk is unavailable for sale in retail stores in Michigan. However, herd or cow share programs exist in the state where members own part of a cow and in return receive raw milk. These programs are not inspected or regulated under Michigan dairy laws. “The public should be aware that raw milk and other unpasteurized dairy products have not been heat treated and, therefore, pose a potentially serious risk to human health,” said Dr. Eden Wells, chief medical executive for MDHHS.

Symptoms of an E. coli infection include severe abdominal cramps, diarrhea (often bloody), and vomiting. Most people get better within one week, but serious complications can develop. Young children are more likely to develop severe illness and a complication called hemolytic uremic syndrome or HUS. A person with HUS will appear pale, tired, and have a decreased frequency of urination as their kidneys may stop working.

People can prevent infection by avoiding contact with infected animals and their environments and by only consuming pasteurized milk and milk products. Raw milk has not been treated to kill bacteria that can cause illness. Pasteurization is the process in which milk is heated briefly to kill any bacteria that might be present.

Unpasteurized milk can contain pathogens that cause a number of serious diseases, such as E. coli O157:H7, hemolytic uremic syndrome, tuberculosis, listeriosis, campylobacteriosis, salmonellosis, brucellosis, and Q fever. Pasteurization is the process in which milk is heated briefly to kill any bacteria that might be present.

Press Release: E. coli Outbreak in New Hampshire

The New Hampshire Department of Health and Human Services (DHHS), Division of Public Health Services (DPHS) is investigating an outbreak of Escherichia coli O157:H7 (E. coli) associated with ground beef. Since June, 12 people have been infected with the same strain of E. coli after eating ground beef. Investigations are underway to determine the source of the ground beef. The safety of ground beef in the United States is regulated by the United States Department of Agriculture (USDA), which is assisting DPHS with the investigation.

“The Division of Public Health Services is working with our federal partners to investigate the source of the ground beef that is causing people in New Hampshire to become ill,” said Marcella Bobinsky, Acting Director of DPHS. “Ground beef is a known source of E. coli and it is important for people to avoid eating under-cooked ground beef whether at home or at a restaurant. Young children and the elderly are especially vulnerable to severe illness with this infection.”

The people who became ill ate ground beef at a number of different locations. DPHS and USDA are actively working to identify the specific source of the ground beef and will provide updates as they become available. This outbreak does not present a risk to New Hampshire residents as long as they strictly follow food safety best practices. Ground beef should be cooked to a temperature of at least 160°F or 70˚C. It is best to use a thermometer, since color is not a very reliable indicator of ‘doneness.’ People should also prevent cross contamination in food preparation areas by thoroughly washing hands, counters, cutting boards, and utensils after they touch raw meat.

Escherichia coli O157:H7 is bacteria that causes severe stomach cramps, diarrhea (often bloody), and vomiting. If there is fever, it usually is not very high. Most people get better within 5–7 days. Some infections are very mild, but others are severe or even life-threatening. Very young children and the elderly are more likely to develop a potentially life-threatening complication known as hemolytic uremic syndrome (HUS). Antibiotics should not be used to treat this infection because they may increase the risk of HUS.

For further information visit the CDC website at http://www.cdc.gov/ecoli/general/index.html, or to report a suspected case contact the DPHS Bureau of Infectious Disease Control at 603-271-4496.

More Sick with E. coli linked to Carbón Live Fire Mexican Grill

The Chicago Department of Public Health (CDPH) continues to work with the owners and staff of Carbón Live Fire Mexican Grill at 300 W. 26th Street as part of our ongoing investigation into an outbreak of Shiga toxin-producing E. coli (STEC). To date, 50 residents have been identified as contracting STEC related to this outbreak. This location remains closed as does a second Carbón location at 810 Marshfield. CDPH continues to recommend that anyone who has eaten at Carbón and is suffering from symptoms to see a medical provider. Individuals may also contact CDPH directly at outbreak@cityofchicago.org.
