Research – Foodborne Illness Outbreaks from Microbial Contaminants in Spices, 1973-2010

Science Direct

This review identified fourteen reported illness outbreaks attributed to consumption of pathogen-contaminated spice during the period 1973-2010. Countries reporting outbreaks included Canada, Denmark, England and Wales, France, Germany, New Zealand, Norway, Serbia, and the United States. Together, these outbreaks resulted in 1946 reported human illnesses, 128 hospitalizations and two deaths. Infants/children were the primary population segments impacted by 36% (5/14) of spice-attributed outbreaks. Four outbreaks were associated with multiple organisms. Salmonella enterica subspecies enterica was identified as the causative agent in 71% (10/14) of outbreaks, accounting for 87% of reported illnesses. Bacillus spp. was identified as the causative agent in 29% (4/10) of outbreaks, accounting for 13% of illnesses. 71% (10/14) of outbreaks were associated with spices classified as fruits or seeds of the source plant. Consumption of ready-to-eat foods prepared with spices applied after the final food manufacturing pathogen reduction step accounted for 70% of illnesses. Pathogen growth in spiced food is suspected to have played a role in some outbreaks, but it was not likely a contributing factor in three of the larger Salmonella outbreaks, which involved low-moisture foods. Root causes of spice contamination included contributions from both early and late stages of the farm-to-table continuum.

 

Research – Antibiotic-Free Turkey Less Likely to Harbor Resistant Bacteria

Food Safety News

Ground turkey from birds raised without antibiotics is less likely to be contaminated with antibiotic-resistant bacteria than conventional ground turkey, according to a new study published by Consumer Reports today.

The group tested 257 samples of raw ground turkey meat and patties, purchased from major retailers nationwide, for Enterococcus, E. coli, Staphylococcus aureus, Salmonella, and Campylobacter and then looked at what portion of these bacteria were resistant to antibiotics. They found high levels of bacteria overall – 90 percent of samples tested positive for one of the five – and more than half were resistant to three or more classes of antibiotics. But the bugs found in products labeled “no antibiotics,” “organic,” or “raised without antibiotics” were resistant to fewer antibiotics than their conventional counterparts.

USA – Extended E.coli O121 Outbreak – Farm Rich Products

Food Safety NewsE.coli O157

Five more victims in four states were added Friday by the federal Centers for Disease Control and Prevention in Atlanta to the list of confirmed cases in the rare Shiga toxin-producing Escherichia coli O121 outbreak associated with Farm Rich brand products.

The additional victims—one each in California, Colorado, and Ohio and two in Florida—bring the total number of individuals infected with the outbreak strain of E coli O121 (STEC O121) to 32.

CDC says 35 percent of the victims have required hospitalization and two developed the kidney-damaging hemolytic uremic syndrome (HUS). No deaths have been reported among the mostly young (81 percent are age 21 or under) victims.

USA – Raw Milk – E.coli O157 Outbreak

Food Safety NewsimagesCAZ9J1WP

Health officials in Wisconsin suspect three patients sickened by the same strain of E. coli O157:H7 contracted their illnesses after consuming raw milk, Wisconsin Department of Agriculture spokeswoman Raechelle Cline told Food Safety News Thursday.

All three patients reside in Manitowoc County, and they include a three year-old child and his or her mother. Officials are currently testing samples of milk from the suspected dairy and will not identify it unless they prove a connection.

“Raw milk was the most likely commonality we’ve been able to identify,” Cline said. The illnesses occurred in March, and the officials are unaware of any additional cases.

Health institutions such as the U.S. Centers for Disease Control and Prevention advise against drinking raw milk, as it has not been pasteurized to eliminate potentially harmful pathogens.

USA – Salmonella Outbreak in Cucumbers

Food Safety News

At least 73 people in 18 states have fallen ill with Salmonella Saintpaul infection thought to be connected to imported cucumbers, according to the U.S. Centers for Disease Control and Prevention.

Fourteen of the patients were hospitalized.

The U.S. Food and Drug Administration placed the firms Daniel Cardenas Izabal and Miracle Greenhouse of Culiacán, Mexico on import alert on April 24. Those cucumbers are no longer believed to be on the market.

The number ill by state is as follows: Arizona (9), California (28), Colorado (1), Idaho (2), Illinois (3), Louisiana (1), Massachusetts (1), Maryland (1), Minnesota (8), Nevada (1), New Mexico (2), North Carolina (1), Ohio (1), Oregon (2), South Dakota (2), Texas (6), Virginia (2) and Wisconsin (2).

Illness onset dates ranged from January 12, 2013 to April 6, 2013. The ill range in age from less than 1 year to 80 years old, with a median age of 23. Sixty percent are female.

Cucumbers are historically not associated with foodborne illness outbreaks. During a massive German E. coli outbreak in the summer of 2011, cucumbers were briefly suspected as the source before the blame was ultimately blamed on fresh sprouts.

USA – Recall – Queso Fresco Cheese – Salmonella

Food Poisoning Bulletin

Salmonella in unpasteurized Mexican-style cheese called queso fresco has sickened at least 13 people in Minnesota who all got it from the same private home, according to state health officials. The Minnesota Department of Health (MDH), the Minnesota Department of Agriculture (MDA) and health officials from the City of Minneapolis are investigating the outbreak and searching for the source of the raw milk used to make the cheese. The sale of raw milk is not legal in Minnesota unless it is purchased on the farm where it was produced.

Eleven people were diagnosed with confirmed cases of infection from the same strain of Salmonella Typhimurium. Eight of them were hospitalized.  Additional illnesses, among family members of those with confirmed cases, were also reported but not confirmed through testing. Two of those people were hospitalized. All of the those who were sickened have recovered

USA – Salmonella Outbreak – Baby Ducklings

Food Poisoning BulletinSalm

An outbreak of salmonellosis in Minnesota has been linked to ducklings purchased from the Tractor Supply Company store in Inver Grove Heights, according to the Minnesota Department of Health. The cases are associated with a multistate outbreak that is being investigated by the CDC.

The patients range in age from 18 to 60 years. All three cases are caused by Salmonella Infantis. The illness onset dates range from late March through early April 2013.

MDH State Public Health Veterinarian Dr. Joni Scheftel said that anyone who handles ducklings, chicks, or other birds should wash their hands thoroughly after contact. “Chicks and ducklings can be a great attraction for children and families this time of year, but they can also be a source of illness. That is why it is so important for people handling them to take steps to prevent infection.”

Young children are more at risk for these infections and are also more likely to develop serious complications from a Salmonella infection. The Salmonella bacteria is carried in the intestines of animals and is shed into the environment. Live birds are a recognized source of Salmonella. The birds can shed the pathogenic bacteria even when they look healthy.

UK – Isle of Man Campylobacter – Animal Rescue ?

BBC NewsCampylobacter

Manx health officials have issued a hygiene warning after several people tested positive for illnesses normally associated with handling livestock.

About five cases of Cryptosporidium and Campylobacter have been reported on the island during the past three months.

It is thought some of those affected may have been involved in helping farmers to rescue livestock after heavy snow last month.

Food Safety Manager Ivan Bratty said simple precautions must be taken.

“These recent cases serve as a timely reminder of the importance of thorough hand washing after handling livestock and before preparing or handling food to prevent infection and the spread of disease in the community,” he said.

“It is also important for anyone suffering from diarrhoea to avoid swimming pools as Cryptosporidium can survive in chlorinated water”.

Cryptosporidium is a disease that is very common in young farm animals and can easily be passed to people who come into contact with those animals- it can lead to sickness and diarrhoea, but is rarely a serious condition for healthy people.

USA – Multi State Salmonella Outbreak – Baby Chicks

Food Safety News104px-More_chicks

A Salmonella outbreak suspected to be linked to live baby chickens may be under investigation in several states, according to a spokesman for the South Dakota Department of Health.

At least four patients in South Dakota — three adults and one child under the age of four — have fallen ill in connection to the outbreak.

The Salmonella bacteria in all four South Dakota cases share the same genetic fingerprint, and some of the patients have had direct contact with baby chicks, state health department spokesman Lon Kightlinger told Food Safety News Monday morning.

The cases came from different parts of the state, and Kightlinger said it was not immediately clear if the chicks involved originated from the same hatchery.
