CDC - Studies on COVID Seroprevalence Indicate Higher Rates of Past Infection

Two reports were posted by CDC MMWR that look at how many people may have actually been infected with the virus versus cases that are actually reported.  By looking at seroprevalence, whether people had antibodies to the virus, both studies showed that at the time of sampling, the actual level or percent of people infected is far higher than what what had actually been reported.   The Indiana study showed that the actual rate may be close to 10 times higher than reported.

• These studies were conducted in late April / early May, and so, if this same rate of non-reported cases of infection is similar, than we do have a much larger population that has encountered the virus.
• These studies show that the mortality rate is lower when looking at the total number of actual cases versus reported.
• They do not know for sure that the presence of antibodies means the people are actually immune.
• The issue of asymptomatic people spreading the virus is a concern, so precautions like mask wearing and social distancing still must be in place.  Protection of high risk populations is also a must.

It is unfortunate that we do not have more information regarding actual rate of infection.  Knowing this would allow better decision making.  This could impact school and business operations.

However, mitigation strategies are still important.  Even though a larger percentage of the population may be infected than we know, there is even a larger percentage that has not been infected.

At this point, reporting negative cases of current infection tells us little.  Not to say testing is not important, but reporting how many people tested negative is not as important as percent positives there are.  Throw in the length of time it is taking to get results back, in same cases 3 to 7 days...or even longer, then the benefit of testing drops, and the reporting becomes less meaningful.

Have you already been infected?

Nasty - Fancy LA Restaurant Scrapes Mold Off of Jams

An LA restaurant was called out for being nasty, including scrapping off mold from improperly preserved jams.   In an LA Times report, 

"Most prominent among the allegations was the claim that Koslow had instructed employees to scrape layers of mold from refrigerated jam buckets, serving the remainder to guests at the restaurant or packaging it in jars for retail distribution"

The owner was evidently a high flyer in the LA restaurant scene, and had taken a Master Food Preserver class.  She even wrote a cookbook on making jams?

Koslow has been nominated for a James Beard Award for her work at Sqirl and was in the second class of the Master Food Preserver cohort in Los Angeles, a program run by the University of California’s Cooperative Extension. She is slated to release her second cookbook, covering the topic of jam making, on July 21.

“All of the retail jam we have ever sold — which is to say the jam in jars that is bought from us and at stores — is pasteurized and canned with the “hot pack” method that makes the growth of mold basically impossible. That same recipe is used in the restaurant, but because the jam is low in sugar and we don’t use chemicals or preservatives, there were occasional instances where mold would develop on the surface."

"The restaurant’s social media statement said that the process for dealing with mold growth was done “under the guidance of preservation mentors and experts like Dr. Patrick Hickey, by discarding jam several inches below the mold, or by discarding containers altogether.”

When contacted, Dr. Hickey backed out of that claim.    In the end, not a good idea to scrape mold off of food surfaces.

The restaurant was said to also have sanitary issues in addition to the mold scraping, including poor cleanliness and vermin.

This Week in Mislabeled Products for Week Ending July 17, 2020

Printing Error on Packaging Results in Missed Milk - Happy Colon Foods, LLC of Oklahoma City, Oklahoma is recalling Happy Colon YUM Shortbread Cookie and Happy Colon Mmmm Chocolate Chip Cookie, because they may contain undeclared milk.  The recall was initiated after it was discovered that Happy Colon YUM Shortbread Cookies and Happy Colon Mmmm Chocolate Chip Cookies containing milk were distributed in packaging that did not reveal the presence of milk. Subsequent investigation indicates the problem was caused by a printing error on labeling.

Undeclared Nuts in Product - Operational or Supplier Issue?  Flagstone Foods LLC, of Robersonville, NC, is recalling its 16-ounce packages of Wegmans Pecan Blend Trail Mix because they may contain undeclared almonds and walnuts. The recall was initiated after a customer notified the firm that the product contained almonds and walnuts that are not listed in the ingredient statement on the packaging.

This Week in Mislabeled Allergens for Week Ending July 11, 2020

Old Formulation in New Package that Misses Sesame Seed - KIND Healthy Snacks (KIND) is voluntarily recalling a limited number of Oats & Honey Granola with Toasted Coconut pouches due to the presence of sesame seeds, which is not listed as an ingredient in the product. The label does list "sesame seeds" under the "May Contain" statement. KIND recently decided to transition away from using sesame seeds in its Oats & Honey Granola recipe. This limited recall was initiated after KIND discovered that the product's previous recipe was used and placed into new packaging that did not disclose sesame seeds as an ingredient. (The product is mislabeled, although Sesame Seed is not currently included in the allergens that have to be identified on the label)

After Watching a Food Safety Video, Some People Still Don't Get It

A research article in J. Food Protection looks at trying to get more people to use a thermometer when cooking ground turkey patties. Yep, if people watch a 3 minute USDA food safety video, they were more likely to use a thermometer.

 "Participants who viewed the video were twice as likely to use a thermometer to check the doneness of the turkey patties compared with the participants who were not exposed to the video (75 versus 34%) and twice as likely to place the thermometer in the correct location (52 versus 23%). Sixty-seven percent of participants who watched the video reported that it influenced their behavior in the kitchen.

I think the kicker is the other side of this....in that 25% of the people who watch the video were still not going to use a thermometer, and if they did 48% were not going to do it correctly.  And 33% were not influenced at all regarding kitchen behavior.  Probably the same people who don't wear masks.

Dog Aging Compared to Humans - A Scientific Evaluation

A recent study looked at how dogs age compared to humans. It turns out that the old adage - one year of a dog life is equal to 7 years for humans. This is not true. It is not a linear progression. Rather dogs mature quickly compared to humans initially, and then that levels out with dogs living the life of an adult for a longer period of their life.

Allergen Removal from Foodservice Counters and Tables

In foodservice establishments, whether at the table or the counter, it is common to see staff dry wipe surfaces, especially when the debris on the surface is dry in nature. However, this is not sufficient to remove allergens from that surface.  A study published in J. Food Protection shows that these surfaces have to be more than dry wiped.

"Although dry wipes and cloths were not effective for removing allergenic foods, terry cloth presoaked in water or sanitizer solution, use of multiple quat wipes, and the wash–rinse–sanitize–air dry procedure were effective in allergen removal from surfaces. Allergens present on dry wipes were transferred to wiped surfaces. In contrast, minimal or no allergen transfer to surfaces was found when allergen-contaminated terry cloth was submerged in sanitizer solution prior to wiping surfaces. The full cleaning method (wash–rinse–sanitize–air dry) and soaking the terry cloth in sanitizer solution prior to wiping were effective at allergen removal and minimizing allergen transfer."
