How did the Yankee Dollar get to be nicknamed a “buck?”

In the 1700s in America, a common medium of exchange and barter was the tanned hide of a deer.

One of the earliest references of the use of “buck” was in 1748, about 44 years before the first U.S. dollar was minted, where there is a reference to the exchange rate for a cask of whiskey traded to Native Americans being “5 bucks,” referring to deerskins. 

Once the U.S. dollar was officially introduced after the passing of the Coinage Act of 1792, it quickly became the leading item used as a medium of exchange, but the term “buck” stuck around. By the mid-nineteenth century was being used as a popular slang term for the dollar.

Wisdom to ponder…   
Jonas Salk
1914 ~ 1995

Discovered and developed the first successful vaccine against polio.

“I pictured myself as a virus or a cancer cell and tried to sense what it would be like.”

“Hope lies in dreams, in imagination, and in the courage of those who dare to make dreams into reality.”

“Intuition will tell the thinking mind where to look next.”
“Nothing happens quite by chance. It’s a question of accretion of information and experience.”
“The reward for work well done is the opportunity to do more.”

“I have had dreams and I have had nightmares, but I have conquered my nightmares because of my dreams.”

“It is always with excitement that I wake up in the morning wondering what my intuition will toss up to me, like gifts from the sea. I work with it and rely on it. It’s my partner.”

When asked if he would patent the vaccine, he replied “There is no patent…can you patent the sun?”

Vibrio Strikes 
on the East Coast
Illnesses cause the 
closing of oyster beds 
as temperatures rise
In September, the Massachusetts Department of Health closed oyster beds in the Boston coastal area due to shellfish that are contaminated with Vibrio bacteria.

Six illnesses linked to contaminated oysters have been confirmed within a 30 day period. The illnesses are being blamed on the Vibrio parahaemolyticus bacteria that thrive in warmer ocean waters. Officials are hopeful that as the coastal water temperature drops a few degrees, the problem will dissipate.

The V. parahaemolyticus infections can cause diarrhea, vomiting, fever and chills within 24 hours. The illness usually lasts about three days.

The Vibrio season in Massachusetts runs from May to October. Health officials are reminding all persons who are at high risk, especially those who are elderly or immune-compromised, to avoid eating any raw shellfish.

According to the U.S. Centers for Disease Control and Prevention (CDC), most people get Vibrio infections by eating raw or undercooked shellfish, particularly oysters.

Less commonly, this organism can cause an infection in the skin when an open wound is exposed to warm seawater.

Another Vibrio pathogen, Vibrio vulnificus, also grows very fast in warm saltwater. The CDC states that an average of 50 culture-confirmed cases, 45 hospitalizations, and 16 deaths are reported each year from the Gulf Coast region (reporting states are Alabama, Florida, Louisiana, Mississippi, and Texas). Nationwide, there are as many as 95 cases (half of which are culture confirmed), 85 hospitalizations, and 35 deaths.

Officials say a spike in cases occurs from May to October when water is the warmest. Infections with this organism can occur from ingestion of shellfish or from entering the skin through cuts or abrasions. Again, consuming or handling raw shellfish and swimming in warm saltwater can put people at risk. People with open wounds can also be exposed to Vibrio vulnificus through direct contact with seawater.

The bacterial infection can cause gastroenteritis, sepsis and can lead to amputation of the infected areas.

Common symptoms from V. vulnificus include vomiting, diarrhea, abdominal pain and fever. Those infected through open wounds may notice redness, blisters, or lesions on their skin.

Hardy Diagnostics offers a chromogenic culture media that can be useful for the detection and identification of Vibrio spp. See the article below.

The increasing incidence 
of Salmonellosis

Salmonella outbreak was reported last month due to contamination found in cucumbers grown in Mexico. 

While Salmonella infection can cause variable symptoms, salmonellosis is often very serious, especially in young, aged, or immune compromised patients. In this particular outbreak, there were 3 reported deaths and over 100 hospitalizations.

Salmonella outbreaks appear to be on the rise; to date, six have been reported in 2015, and a similar cucumber related outbreak happened in early 2014. Although many associate Salmonella with poultry or poultry products, cucumbers and other produce can become contaminated and cause outbreaks. 

Proper food safety is necessary to avoid future epidemics such as these.  Simply washing and rinsing raw produce under running water (no soaps or detergents) before consumption is a good safety measure to ensure food is safe to eat. Additionally, the FDA recommends using a clean produce brush on firm or hard-skinned produce, such as cucumbers, before eating them. This not only reduces the bacterial count, but also helps to clean off any dirt, fertilizer, or grime that may have accumulated on the outer surface of the fruit or vegetable during growth or distribution.
Food testing is another critical part in identifying the source of the outbreak and in routinely ensuring public safety. If adequate techniques are not used, contaminated products can reach the consumer. In addition, if records of food products are not maintained to document the chain of custody through distributors or suppliers, this may delay the ability of investigators to trace back outbreaks to their source.
Currently, there are many ways to successfully screen, culture, and identify Salmonella using reference methods such as USDA FSIS, FDA BAM, AOAC, or standard clinical media based on the sample or specimen type. 

Hardy Diagnostics offers a variety of general culture media, as well as selective and differential media, and rapid tests to assist laboratories. Below is a small selection of some of the products Hardy offers.
