Apples: Listeria reduction most effective in CA rooms

857552668

New studies suggest the preponderance of Listeria reduction occurs during apple storage and that additional reduction during processing is limited by apple surface microstructures.

Two recent food safety research studies from the School of Food Science at Washington State University and the Washington State Tree Fruit Research Commission indicate that when used properly, ozone can safely disinfect your apples during storage significantly reducing the risk of entrapped Listeria cells in the microstructures of the fruit during processing and packing.

STUDY #1 – Ozone Gas + CA results in 5.0 Log CFU/apple reduction (GRAPH BELOW)

“Continuous application of low doses of gaseous ozone in CA storage facilitated L.innocua reduction and resulted in ≈5.0 Log CFU/apple reduction after 30-week storage. In addition, continuous low-dose ozone gas inhibited apple background flora without negative impact on fruit quality.”

STUDY #2 – Apple surfaces harbor Listeria contracted in the dump tank or flume

“Apple Surface morphology was found to be (an) important factor in attachment of L. innocua. Microstructures serve as harbor sites for bacteria attached by physical entrapment. Settled in hard to reach sites, bacteria are protected from cleaning operations and disinfection.”

FORMER USDA UNDER SECRETARY for FOOD SAFETY JOINS TRISTRATA GROUP BOARD

IMG_2144 retouched.jpeg

Elisabeth Hagen, M.D., the former food safety chief at the U.S. Department of Agriculture has become a member of the Board of Directors at TriStrata Group.

During her tenure at the USDA’s Food Safety and Inspection Service, Dr. Hagen’s focus on preventing foodborne illness was the agency’s top priority.  Prior to her role as undersecretary she was the USDA ‘s Chief Medical Officer and Senior Executive in the Office of Public Health Science, where she played a vital role in developing and executing the agency’s scientific and public health agendas.

“As a physician and mother of two children, I know how important it is for families to feel confident that the food they put on their tables every night is safe and healthy” said Dr. Hagen, “I appreciate the potential of ozone to do just that in a way that reduces the environmental impact of the industry and the health risks to employees.”

FACT or FICTION: Ozone kills Vibrio

Does ozone kill Vibrio?

Yes, at defined ozone concentrations and contact time. 

If you’re processing peeled shrimp or shucked oysters, ozone can help defend against Vibrio (and Listeria).  

Additional research needs to be conducted on un-shucked oysters and shrimp, as well as crab and lobster in the shell. 

TriStrata Group is seeking partners to conduct research with these products, as well as additional applications in the Seafood Market.

How much does a Food recall cost?

In 2018, US companies experienced 213 pathogen related recalls. What did that cost?

We recently attended a food sanitation conference and someone in the audience asked the panel, “How much does a recall costs…or a range I might expect?” Surprising no one had an answer.

We thought this was an important question because it helps us all better understand the cost of waiting to long to address food safety concerns or not having enough effective interventions to successfully eliminate the risks.

So we did a bit of research and here is what we found…

Over half of all recalls cost more than $11 million.

The best source we discovered was published by GMA (The Association of Food, Beverage and Consumer Products Companies) and Ernst & Young. The full report can be viewed by clicking <here>

Graph: ESTIMATED FINANCIAL IMPACT AS A RESULT OF A RECALL Including sales loss, direct recall costs, etc

Adjusted for 2018 US dollars.

48% of recalls cost less than $10 million

47% of recalls cost between $11 million to $110 million

5% of recalls cost more than $112 million

The implementation of additional food safety interventions could have helped these companies reduce their risk and financial impact.

FACT or FICTION: All ozone providers are the same.

All ozone providers are not the same.

The services and support provided vary greatly and the disparity can mean the difference between outcome success and failure.

Several things you should ask any ozone provider you are considering:

1. Do you have service techs in my area to maintain and service the ozone generating system?

TriStrata has the largest nationwide field service team to keep your ozone equipment maintained properly and repairs made quickly.

2. Does your company focus solely on the food Industry?

Successful implementation of ozone requires an in-depth knowledge of food safety, processing procedures, HACCP, and ozone’s capabilities. TriStrata focuses solely on the food industry.

3. Do you have a monitoring and data logging system? Does your customer service team monitor it for irregularities?

TriStrata provides remote monitoring & access, data logging, AND dedicated system analysts that actively work to rectify alarms remotely.

2.     Localized Service.

We’ve expanded our local service team to expedite maintenance and repair.  Our Pro level service plan offers active ongoing monitoring with 24/7 critical fault response and onsite parts storage.

3.       In-plant Validation.

Of course, you’ll need to provide support documentation as part of your HACCP plan. Our team can work with you on documentation.

We welcome the opportunity to discuss your food safety concerns, recent TriStrata Group in-plant efficacy data and to tailor a solution to fit your needs.  To connect with us: <click here>

FACT or FICTION: You can reduce antimicrobial usage with ozone.

Screen Shot 2019-01-21 at 5.21.29 PM.png

Consider ozone as an additional food safety hurdle in your food safety microbial intervention strategy for several reasons:

1.     Reduce antimicrobial usage.  Ozone can maintain and often reduce the incidence of microorganisms while decreasing the usage and costs of other microbial interventions. 

2.     Reduce safety risks.  Ozone will reduce the hazards associated with your team handling hazardous chemicals.

3.     Reduce complexity & footprint.  Ozone is generated on-site.  No need for additional orders, storage and waiting on delivery.

4.     Reduce your environmental impact.  Ozone starts and ends as oxygen.  We can help you achieve clean labeling and sustainability goals.

Dr. Achour Amiri, Plant Pathologist at WSU recently published an article about the importance of room and bin sanitation to reduce postharvest decay for apples and pears. His research concludes a 60-90% spore kill percentage on wooden bins and empty rooms using ozone gas/fog with a 2-48 hour exposure.
