Contamination Found in Cheese, Don't Worry, the Cheese is 15,000 Years Old

Researchers found remnants of cheese in an Egyptian tomb, dating about 13th century BC.  Along with the cheese, they found "peptides in the food sample suggest it was contaminated with Brucella melitensis, a bacterium that causes brucellosis. This potentially deadly disease spreads from animals to people, typically from eating unpasteurized dairy products. If the team’s preliminary analysis is confirmed, the sample would represent the earliest reported biomolecular evidence of the disease."

It is rumored that foodborne illness lawyers have been canvasing locals to see if they had very distant ancestors who may have fallen mysteriously ill as well as rooting through tombs to see if any mummies have the same pathogen markers.

Cause Of Chipotle Outbreak is C. perfringens - Indicating Improper Food Handling Practices

A few weeks back, a Chipotle restaurant in Ohio was the site of a foodborne illness outbreak where 647 people were reported as being affected.  The cause of the outbreak was found to be Clostridium perfringens contamination, based on testing of those who became ill.  Investigators were not however, able to find the exact food source.

The fact it was a Clostridium perfringens outbreak is an indicator of a bad food handling practice.  C. perfringens becomes an issue when cooked food is held at an improper temperature (probably in the  80F and 110 range) for a long time.  For example...beef used in a burrito.  The meat is cooked, but spores of C. perfringnes survive.   Not a problem if meat is cooled rapidly and refrigerated or kept hot (>135F).  But if that meat is left out on the counter over night and then warmed for serving....boom.  The organism grows to high numbers (infectious dose >10E6, infects the person in high numbers, produces toxin in the gut, and then in about 16 hours..it is watery diarrhea and cramps for 12 to 24 hrs.   At that point, you are thinking #@$%! burritos.

When news was released, many thought it was Norovirus, which even a good facility can have an issue when a worker is a carrier but doesnt know..  But C. perfringens...that is just bad food handling practices.  A sign that a restaurant is not keeping an eye on the ball.  And with that many people ill, that means that there was a lot of product that was temperature abused.

The company announced that food workers will be required to do quarterly online training and assessment.  "The test is an "e-learning type module that all employees will be required to complete on a quarterly basis in addition to their daily food safety routines and annual food safety training," Chipotle spokeswoman Laurie Schalow told Business Insider on Thursday. The company also said Thursday it will retrain all employees on top food-safety priorities. The training will begin next week during employees' shifts at restaurants across the United States."

Who Knew? Think Twice Before Drinking from the Garden Hose

A news report from Hawaii where rat lungworm, a parasitic infection, can be spread when an infected snail, one of the parasite hosts, climbs into the garden hose and then one drink water from the hose.  Okay, this parasite is not common in the continental US, but is common in Hawaii and has been found in Louisiana and Florida.  That is not to say it can't make its way to other states, because while the one definitive host is the snail, the other definitive host is the rat.

Still, something to consider before taking that gulp of water from a hose that has been laying on the ground for weeks.....you never know what could have crawled in there.

From the CDC:

  • "Angiostrongylus costaricensis is a parasitic nematode (worm) that resides in rodents and uses mollusks, such as slugs, as an intermediate host. Rats, such as the cotton rat, transmit the larvae through their feces. Slugs then ingest the larvae. Humans are accidental hosts of the parasite. The parasite is not able to complete its life cycle in humans and eventually dies in the abdomen.  "
  •  "In humans, juvenile worms [can] migrate to the brain, or rarely in the lungs, where the worms ultimately die." 
  • "Most cases of infection are diagnosed in Southeast Asia and the Pacific Basin, but the parasite has also been found in Australia, some areas of Africa, the Caribbean, Hawaii and Louisiana."  [It has also been found in Florida]. 
  • "Very few cases have been reported in the continental United States. In 1993, a boy in New Orleans got infected by swallowing a raw snail “on a dare. ” The type of snail he swallowed isn’t known. He became ill a few weeks later, with muscle aches, headache, stiff neck, a slight fever, and vomiting. His symptoms went away in about 2 weeks, without treatment of the infection."

Research - Norovirus Transmitted via Membrane-bound Clusters

NIH research found that the highly virulent stomach viruses such as Norovirus may be spread in membrane-bound clusters....think multipack.   We have normally thought the virus was spread as individual particles, but this research shows that the virus when excreted is like a horde of viruses traveling to the next gig in a party bus...via the fecal-oral route.  This protective membrane allows the virus to evade internal host systems and deliver a mob of viruses to the invasion site.

FDA Investigation into E.coli Outbreak Linked to Romaine Lettuce Finds Cattle Feeding Operation as Potential Source

The FDA continues their investigation into the E. coli outbreak, but are looking at a Concentrated Animal Feeding Operation as a potential source.  This CAFO is stated as being able to hold up to 100,000 head of cattle.

E. coli and 100,000 pooping cattle....that may be a good place to be concerned about especially if there is access from that operation to the canal system.  But the release was short on information specifically the distances from the CAFO to the canal system, and then down to the farming area?  Can cattle ever get to the water?  Can rain water runoff make its way into the CAO? 

Had anyone raised a concern about the locale of the CAFO to the canal system?  Has anyone tested the water if there were a concern?  As a main component of produce safety, water quality and the potential for contamination should have been evaluated.  And as part of that, the potential contamination by farm animals should also have been evaluated.  While testing can be unreliable, a risk analysis of a nearby CAFO should have been undertaken.    But at this point, it is hard to glean this information that FDA has released.

In this outbreak, 210 were infected across 36 states with 96 hospitalizations and five deaths.  In a June 28th news release, FDA and CDC reported that the E. coli strain was found in the irrigation canal.

FDA Provides Update of Cyclospora Outbreak Associated with McDonald's Salads

As of August 2, 2018, there have been a total of 395 laboratory-confirmed cases of Cyclospora infection reported in people who consumed salads from McDonald’s restaurants; the cases were reported by 15 states.   McDonald's immediately discontinued sales of the salads upon notification.
FDA found cyclospora in product packed by Fresh Express, but by the time the analysis was complete, the product had date-expired.  
Fresh Express recalled product that went to Caito Foods and thus the recall by that company.
