Relax—you actually don’t need to sanitize your food

On Sunday, I posted an article about sanitizing your food after you return from grocery shopping. The thing is, the medical professional who posted the original clip went a bit overboard in terms of how sanitary he felt he needed to keep his food once retrieved from the grocery store. The truth is, not everything the doctor says in his video is strictly correct and he is no food safety expert, as has been pointed out to me. However, for the most part my textual commentary doesn’t contradict what I’m about to share and I am happy to give Dr. Don Schaffner his due:

Buckle up, readers, as it’s about to get serious! Thirty-two more tweets, seriously!

Unfortunately, the link above to my original article with take you to that video but if you haven’t hit play on the video, and just read my commentary, you should be fine. Please, trust Dr. Don!

Sometimes I roll my eyes at my fellow writers when they they try to come up with Science Fiction ideas, since I did study undergrad Physics and read a lot of science books. I feel you Dr. Don!

Here here! I already outlined most of what was right in the video in my original post. I think I may have misspoken on how to wash produce but I’ll save that commentary for later.

There’s a bit of nuance to this, but what the good Dr. Don is saying is there is a difference between a random but not yet denatured strand of viral RNA, which in itself isn’t particularly harmful—at least, not infectious—where as a live virus was not observed. As in, the crown-like outer shell of SARS-CoV-2, a.k.a. the Coronavirus, the “Crown Virus”. Without the outer shell and crown-like protrusions, the virus has no way of penetrating cells, be they eukarya, bacteria, or archaea. Note, this pathogen only infects eukaryotes, though most viruses are harmless, only infecting bacteria.

More fundamentally, though, Dr. Dan points out that the CDC Study that came up with the 17-day number for RNA was never published in a peer-review paper where the methodology and techniques used could be scrutinized and dissected. Without the process of peer review, the observation is as good as anecdotal.

This was one of my biggest beefs with the video too. I mean, it’s one thing in the winter in Lansing, MI, where the outside might already be the temperature of your freezer. But that won’t work in Florida, not by a long shot. So unless you’re gonna be like Thomas Jefferson and truck in ice from Canada to keep your food from spoiling, don’t leave your perishable food in the garage!

Exactly!

This is a very good point. One of the ways the SARS-CoV-2 deactivates is through desiccation. If the virus is in a medium that allows it to dry out, it will no longer be effective. This is why spittle from sneezing is the most dangerous.

The virus is highly communicable, to be sure, but its transmission with respect to someone with the virus touching an item on the shelf, putting it back, and then having you grab it is exceedingly unlikely. And by the time you get to it, it’s quite likely SARS-CoV-2 has already dried out and perished.

I have to agree, as different packaging materials will allow the virus to remain active long than others, and again, as state above, it’s unlikely by the time you pluck the item from the shelf that it would still have any active virus on it even if it had once.

Washing your hands before eating should be second nature anyway. As Dr, Don says, you can remove the item from the packaging, put it on a clean plate, and then wash your hands before eating and any contamination on the packaging will have been removed from the equation.

Wørd!

There are good reasons not to use soap to wash your produce and I will admit I got that wrong before. Soap dissolves cell membranes and while most produce is covered by dead epithelial cells—like those on the outer layers of your skin—and thus won’t likely cause cellular damage to your food, but if you slice the food it could spoil its flavor and if you fail to wash it all off and it gets in the nooks and crannies of your consumables, Dr. Don is right, you’re itching for a tummy ache. The oily residue soap normally removes isn’t a big issue on produce and thus a simple water bath should be sufficient for cleaning your produce.

Precisely!

Even the prescient Dr. Ignaz Semmelweis knew that hand washing wasn’t a panascia. It reduces the change of killing a mother giving birth, but even if done right, it isn’t perfect. Soap and water are great for removing both hydrophobic and hydrophilic substances from your person, but not every pathogen is removed by such reactions. SARS-CoV-2 is damaged because of its hydrophobic coating, but the same isn’t true for all toxic substances.

Indeed, human skin has many friendly microbes that help keep the skin clean and fresh. You wouldn’t want to boil those off anyway, even if you could. Love your friendly microbes. Just use soap and water to kill SARS-CoV-2. That M*th*r F*ck*r must die!

This is another good point. Not all handwashes are equal. I try to do a rather complex technique when washing my hands which I may document another day, but the long and short of it is, just rubbing your hands together isn’t enough, and even my technique isn’t one hundred percent effective.

Great point! Early food preservation in wine bottles with their tartaric acid may have worked for Napoleon’s army, but when we started using steel and aluminium cans, or even glass, we had to be very very sure everything was sterile. Watch any number of episodes from Comment C’est Fait (How It’s Made chez É-U.) to see how this is done.

Remember the words of François-Marie Arouet, a.k.a. Voltaire, “Le mieux est l’ennemi du bien.” (Perfection is the enemy of good.)

This is one point I did make in my original article. Glad to see my point is backed up by Dr. Don.

This one is simply a caveat emptor. Don’t assume a product can kill viruses. Indeed, there are many ways product makers can use language that makes it seem like it’s effective against pathogens, but unless there is peer reviewed literature to back it up, sorry, it’s not magic. It won’t protect you against SARS-CoV-2 any better than simply washing your hands.

There is something to be said for the security blanket of feeling better. But, yes, they won’t help and are no better than a simple cold-water bath.

Or for treating the fabric of your home made N95 mask.

I like using reusable bags and agree washing them like any fabric is a wise idea. If you must use disposable bags, please use ones that are recyclable or compostable.

In other words, keep your bags close but be more mindful of social distancing and that the bagger uses proper sanitary techniques. But again, the likelihood that someone with the virus has used that same checkout stand recent-enough for the virus to still be active is very likely, and most grocery stores, like Wegman’s will do their best to sanitize the checkout counter between each customer during Covidapolis.

Keeping them in your car is a good idea. I always keep my MOM’s Organic Market bag in my car so it’s ready whenever I go there.

Wash your hands!

I have indeed noticed Wegman’s doing just that. They are, IMHO, doing a great job!

Know what you want, like Low Acid Orange Juice, and head straight over. Keep those two meter buffers to keep safe!

If you can get hand sanitizer, then it’s great when there isn’t soap and water available. But when you have soap and water, always prefer that.

Done in the most complete way possible Dr. Don!

Shelter in place, y’all, and use Zoom to see a friendly face!

Much obliged Dr. Don! Happy to help promote good science, sound food handling, and how to weave a great yarn, and sew a great mask!

Bon appetit, mes amis!

2020 Presidential Primary: VOTE!

It’s that time of year again. Time for the world’s second largest Democracy by population, and richest Democracy by overall GDP to vote to select who is the best to represent their party on the Presidential stage.

Voting through most of American history has been difficult. Our nation, like almost every Democracy, has political parties and every election it always comes down to just two choices: Conservatism or Progressivism. Progressives believe in progress, a government that is strong and protects its citizens from business. Conservatives believe in small government, state’s rights, and traditional values.

In 2020, Americans call Conservatives Republicans, and call Progressives Democrats. In 1888, Americans called Conservatives Democrats, and Progressives Republicans. In 1860, we called Progressive Abolitionists Republicans and Progressives who weren’t were Whigs, and Conservatives were Democrats. In 1796, Progressives were Federalists and Conservatives were Democratic-Republicans.

While all these elections were interesting, there’s one even more interesting. One more interesting than the 1888 election, where Grover Cleveland the Conservative won the Popular Vote but lost the Electoral College to Progressive Benjamin Harrison. One more interesting than the election of 1860, where Abolitionist Progressive Abraham Lincoln won the election with only 40% of the Popular Vote in a Three-Party Race. One even more interesting than the election of 1796, where the electoral college appointed the highest ballot winner to the Progressive John Adams, thus making him President, while the Conservative Thomas Jefferson had the second most votes, making him Vice President.

That last arrangement was so untenable that the Twelfth Amendment was passed. This amendment entrenching the party ticket system with our nation for the past 220 years. It give us the modern interpretation of Article II, Section 1, which in turn grants sole power to state legislatures to determine how that state’s electors are chosen.

But even that election isn’t the one I want to talk about.

The Election of 1824

The election of 1824 was a cantankerous one. That year, the Federalist Party had dissolved and the nation became a single party state where everyone claimed to be a member of Thomas Jefferson’s Democratic-Republicans. Under that backdrop, in the first election for which we have popular voting data, there were a slate of four candidates: John Quincy Adams, Andrew Jackson, Henry Clay, and William H. Cranford.

CandidateElectoral Votes
Andrew Jackson99
John Quincy Adams84
William H. Crawford41
Henry Clay37

With four candidates running, for what was so far the only time in history, no-one received a majority of electoral votes, 131. As such, under the Twelfth Amendment (as amended by the Twentieth Amendment), the election is decided by taking the top three or less candidates and having each state’s Representatives voting on which of the candidates they prefer, with the state going to whomever the most Representative for that state voted for. Each state gets one vote, and whoever gets a majority of states becomes President. If no candidate receives that state majority, then the vote is recast until a majority is decided.

In 1824, this is exactly what happened. Of the twenty-four states at the time, thirteen were needed to decide the election. Fortunately, since Henry Clay, having been eliminated as not being in the top three, backed John Quincy Adams, meaning that only a single ballot was required in the House of Representative to elect John Quincy Adams as President.

CandidateState Votes
John Quincy Adams13
Andrew Jackson7
William H. Crawford4

If this were to happen in 2020 thanks to a third party candidate making it impossible for either the President or the Democratic Challenger to receive at least 270 Electoral Votes, then I personally feel the nation would be aghast. Most Americans don’t know about the Electoral College Voting Majority requirement or the state-based Congressional voting system, and would indeed by shocked to know that’s just what their Constitution says.

There must be a better way.

Ranked Choice Voting

Like the election of 1824, the modern Primary system seeks to choose a winner by strict majority among a list of party-faithful Presidential Candidates. If no candidate receives a majority of votes on the first ballot, SuperDelegates in the Democratic Party (Republicans don’t have SuperDelegates) are used to put their fingers on the scale and the required majority changes to reflect this.

Wouldn’t it be easier if we could just pic the majority on the first ballot? If people in 1824 could just say without Clay and Crawford they wanted Jackson?

All these problems could be solved with Ranked Choice Voting. With Ranked Choice Voting, or RCV. Under RCV, you can say you prefer Crawford, but if your second choice is Jackson, then Adams, and finally Clay. Or you could say, like me, your first choice is Elizabeth Warren, because, among other things she supports the National Popular Vote Interstate Compact, but my second, third, fourth, and fifth choices would be among the various other candidates.

What you do with that is a whole other question. Clearly, you could just ignore all but the first choice and see if anyone gets a majority. But that’s what we have now, and clearly a majority isn’t guaranteed.

Another possibility, very possible is Instant Runoff Voting (IRV), where, instantaneously, a mock election is conducted with all the first-place candidates, and if no-one receives a majority, the candidate receiving the least amount of votes is eliminated and anyone voting for him or her will instead vote for their next choice. This algorithm is continued until one candidate receives a pure majority.

The problem with IRV is that it doesn’t guarantee a Condorcet Winner. The reason is easy to see if you have a series of ballots where, in aggregate, a majority prefer A over B, a majority B over C, and a third, unique majority C over A. In the vaguest case, this could produce C as winner even though a majority prefer A over C.

Another alternative, one I prefer, is the Schulze method. It is Condorcet and will match IRV when IRV doesn’t contain, for instance cycles like above. However, Schulze is a rather complicated, geometric voting system. Were it up to tabulations by hand of hundreds of millions of RCV Ballots, this would be impossible. But with modern computers, it’s facile.

Whatever voting system we use, it’s better than the system we have now with throwing the election to the House of Representatives or using SuperDelegates to ensure majorities.

And whoever you vote for this coming Super Tuesday or beyond, vote wisely, be informed, and vote with a free hand because the decision is yours. Just make sure you go out and vote!
