Bad hygiene and the virus can cause losses


Did you know that bad hygiene can cause even the stock market to fall.   Fears about broadly rising coronavirus cases drove the Nasdaq and S&P 500 to their biggest drop in nearly two months, and sent benchmark yields to their largest decline in over 3 months as investors sought shelter from the uncertainty.

The History of Hygiene and Sanitation

The History of Hygiene and Sanitation

The Human Right to Water and Sanitation was recognized by the United Nations (UN) General Assembly in 2010. Sanitation is a global development priority.  The estimate in 2017, 4.5 billion people currently do not have safely managed sanitation.
History of Sanitation WHO document 
  • In 2017, 45% of the global population (3.4 billion people) used a safely managed sanitation service.
  • 31% of the global population (2.4 billion people) used private sanitation facilities connected to sewers from which wastewater was treated.
  • 14% of the global population (1.0 billion people) used toilets or latrines where excreta were disposed of in situ.
  • 74% of the world’s population (5.5 billion people) use d at least a basic sanitation service.

  • 2.0 billion people still do not have basic sanitation facilities such as toilets or latrines.
  • Of these, 673 million still defecate in the open, for example in street gutters, behind bushes or into open bodies of water.
  • At least 10% of the world’s population is thought to consume food irrigated by wastewater.
  • Cropland in peri-urban areas irrigated by mostly untreated urban wastewater is estimated to be approximately 36 million hectares (equivalent to the size of Germany)
  • Poor sanitation is linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid and polio and exacerbates stunting.
  • Poor sanitation reduces human well-being, social and economic development due to impacts such as anxiety, risk of sexual assault, and lost educational opportunities.
  • Inadequate sanitation is estimated to cause 432 000 diarrhea deaths annually and is a major factor in several neglected tropical diseases, including intestinal worms, schistosomiasis, and trachoma. Poor sanitation also contributes to malnutrition.
A history of Hygiene in UK is given here.   A few choice excerpts are given below.

1750 – A letter from Lord Chesterfield to his son urges the use of a sponge and warm water to scrub the teeth each morning. The recommendation of using one’s own urine in France was widely flouted by Fouchard, the French dentist. Gunpowder and alum were also recommended.

1834 – The 1834 London Medical and Surgical Journal describes sharp stomach pains in patients with no evidence of disease.  This led them to believe “painter’s colic” was a “nervous affection” of the intestines occurring when lead “is absorbed into the body”.

1847 – A physician called Ignaz Semmelwis found childbed fever occurred in women who were assisted by medical students. He found students who assisted in childbirth did so after autopsies. After instituting a strict hand washing policy, deaths dropped by 20 fold within 3 months.

1854 – In mid-18th century England, outbreaks of cholera led to an epidemic. A physician called John Snow observed that cholera seemed to spread via sewage-contaminated water. This was mostly noticed around a water pump in Broad Street, London. John removed the pump handle and the spread was instantly contained.

1858 – Hot weather struck the capital in 1858, drying up the River Thames and leaving pure sewage and other wasted piled up and exposed. This was the start of ‘The Great Stink’, forcing Parliament to close for the day and eventually initiating a reform of the sewerage systems and cesspits.

1861 – The modern flushing toilet. Thomas Crapper didn’t invent the flush toilet but is understood to have made major contributions towards its development by implanting a modern septic system that pumped soiled waters out of the city. However this particular subject is still heavily debated.

1920* – Lysol was sold as a genital disinfectant and birth control method. Lysol ads proclaimed a host of benefits for every gynecological need, and was the leading form of birth control from 1930 to 1960. Lysol is a poison that can cause burns and itches after the first drop.

*Source   “The first Lysol Brand Antiseptic Disinfectant was introduced in 1889 by Gustav Raupenstrauch to help end a cholera epidemic in Germany. The original formulation of Lysol contained cresols. This formulation may still be available commercially in some parts of the world. Formulations containing chlorophenol are still available in the United Kingdom.In 1911, poisoning by drinking Lysol was the most common means of suicide in Australia and New York. One of the active ingredients, benzalkonium chloride, is highly toxic to fish (LC50 = 280 μg ai/L), very highly toxic to aquatic invertebrates (LC50 = 5.9 μg ai/L), moderately toxic to birds (LD50 = 136 mg/kg-bw), and slightly toxic (“safe”) to mammals (LD50 = 430 mg/kg-bw)”. 

1900’s – Autoclaves

The difference between sterilization and pasteurization

  • Sterilization targets all microorganisms and vegetative spores even the hardy gram-positive ones.  Complete destruction of microorganisms is the target.  High steam temperatures are used.  After sterilization, a shelf-stable (food) product is obtained.
  • Pasteurization targets pathogens and vegetative cells. It is generally done at milder temperatures e.g. with hot water. After pasteurization, refrigeration of the product may be required to prevent spoilage.

SaniZap machines and high-temperature steam above its inversion temperature can be used for sterilization provided the correct residence time and temperature are employed.

What is sanitation, and disinfection, and how do they compare with sterilization? 

What is hygiene? 

What are MightSteam and HealthySurface?

Should we stop cleaning? What is clean?

Should we stop cleaning? What is clean?

There is an opinion that perhaps we should stop cleaning surfaces.  Recent NY Times article.

We respectfully disagree.

This is similar to saying we should not wash our hands or we should reduce hygiene.  We think the problem has more to do with the excessive use of toxic chemicals (yes, chemicals in concentrations are toxic).  We do not recommend UV Ultra-Violet because the damage effects of UV on human tissues and cells are cumulative.

We recommend steam.  Why Steam?

The History of Hygiene and Sanitation

How does one measure the hygienic quality or cleanliness of a surface? (Please click for measurement information).

HealthySurface® is a service in which surfaces are restored to, and maintained at, an original condition utilizing treatment provided by the superheated steam process and apparatus of SaniZap®.  HealthySurface® provides the removal of foreign substances from objects and surfaces to initial conditions including cleanliness, texture, or scent.  Cleanliness, as used here, may be defined as the removal of any content not initially present on a surface. Mighty steam is low oxygen above common inversion temperatures. A treatment provided by HealthySurface® will remove or reduce microbes when employed properly . However, repeated applications or other sanitation processes could be necessary to maintain these conditions on a more permanent basis. How long a microbe can live on a surface often depends on the microbe. There is no hard-and-fast rule for how long a virus can survive outside of a host (some published information is given below – see also news). The type of surface and environmental temperature and humidity all come into play. Deep-cleaning with SaniZap® is recommended particularly for reaching vegetative bacteria.

Please read below for reported information on virus residence on surfaces.  Please note that technical and microbiological information is constantly evolving.  Bayzi Corporation will continue to add to news as more information becomes commonly available.

Our Story

Some years ago we had a water main pipe breakage at our company.  The cleaning crew did a great job but we were never sure how clean the place was.

Being the experts we are with high temperature steam, we decided to pursue sterility level cleaning. The MightySteam® technology soon emerged as a new way to make instant steam that could eliminate any microbe within seconds.

Reliable portable models – SaniZap® solves this problem with cutting-edge, highly innovative products, covered by several patents.


Let’s Compare Steam with All Other Methods  

Chemicals and UV present considerable dangers.  These are well documented so can be easily searched on the web.  The harm to humans is cumulative.  Steam is the best solution as it is water based – so CLEAN by definition.  However, it has to be the correct type of high temperature steam. This is the breakthrough technology that SaniZap® offers.  The table below compares chemicals, low temperature carpet cleaning steam (vapor cleaners) and the SaniZap® antimicrobial steam.


Do more with SaniZap® Steam

In addition to antimicrobial use, SaniZap® can be used for several levels of cleaning  like removal of old dust, dust mites, bird droppings, rust, paint, wall-paper, grease removal, eliminating black mold and more.  We recommend the SaniZap-600-4-240 model for all of that.  This model also allows a soap/cleaning agent and high temperature steam setting  for rapid degreasing, floor cleaning and similar use. Clean Anything from Soft to Hard Surfaces.

Sanitation and cleaning in the food industry means  adequate treatment of food contact surfaces  to destroy vegetative cells of microorganisms. SaniZap® steam is the solution.

Steam – the Ultimate Microbe Buster

Superheated steam is a known anti-microbial agent and has been used for sterilizing for decades, but confined to autoclaves.   Steam at the correct temperature and residence time is a rapid sanitizer.  For the first time, the  portable SaniZap® machines make even higher temperature steam than autoclaves possible, instantly.  SaniZap® steam passes the important chemical indicator tests that autoclave have to (Class 4 and Class 6 indicators shown).



“Enveloped viruses such as SARS-CoV-2 and HIV can be readily inactivated with heat.   The Bayzi Corporation target for employing high temperatures that are capable of inactivating viruses within a few seconds with steam appears to me to be highly likely to succeed.” Albert B. Sabin Professor and Director, Infectious Diseases, Cincinnati Children’s Hospital Medical Center

Bayzi has created a Science and Engineering team with experts from from Universities, Hospitals and EPA.

A brand-new technology platform for antimicrobial, antipathogen, and general cleaning to provide a green and healthy alternative to toxic chemical sanitizers.
