This holiday season, you may be stocking up on canned drinks for parties and guests. Well, you'll want to clean off those cans before handing them out!Investigator reporter Jace Larson tested soda cans for bacteria, and what he found was pretty gross.The cans tested came from a variety of places, including grocery stores, convenience stores, vending machines and cans stored in a home. All but one of the cans tested had mold on it.The highest mold count was 600 colonies of mold. That can came from a grocery store.This type of exposure could make people with compromised immune systems or lung disease sick.To put that number of colonies into perspective-- a flooded home could have 2,000-plus colonies of mold, while a condemned home could have roughly levels around 36,000.However, microbiologist Helene Ver Eecke, with the Metropolitan State University of Denver, says the 600 colonies of mold isn’t really a cause for concern.“Regular microbial load that we are constantly dosing ourselves with everything that we touch with everything we breathe,” Ver Eecke says. “It's just part of being human.”One soda can did test for bacteria levels that would be slightly concerning. The can—purchased from a convenience store--had the highest levels, with 3,700 bacteria colonies on it.But compared to dry cereal mixes, which can have up to 100,000 bacteria colonies and deemed safe to consume by FDA standards, the colonies found on that can were significantly less."There was one sample that came from a convenience store that had a higher bacterial count than samples, which makes sense because they were probably stocked probably appropriate for people to wear gloves when stocking," explains Ver Eecke.If you’re worried about the amount of bacteria, Ver Eecke recommends seeking other options."There may be other options for you a bottle or other things to try to help keep you safe." 1901

This weekend, most Americans will set their clocks back one hour Saturday night as everyone reverts back to standard time.Every state except Hawaii and Arizona observe Daylight Saving Time in the summer months.The idea of Daylight Saving Time has been around for more than a century for a variety of reasons, including more evening daylight and saving energy.Germany was the first country to experiment with it, and it wasn't fully adopted in the United States until 1918 when "An Act to save daylight and to provide standard time, for the United States" was passed.Once this law was passed, it established the time zones we use today — Eastern, Central, Mountain and Pacific — and specified when Daylight Saving Time would begin and end.Two years later, however, the Daylight Saving Time option was repealed and left up to localities to decide whether or not they'd change their clocks.Nationwide Daylight Saving Time returned for almost three years during World War II when President Franklin Roosevelt instituted "War Time," or year-round Daylight Saving Time.It wasn't until 1966 when President Lyndon Johnson signed the Uniform Time Act, which ended a lot of confusion by setting standards for when Daylight Saving Time would begin and end. It also required every state to participate unless a state voted to keep the entire state on standard time.Daylight Saving Time was extended with the Energy Policy Act of 2005, so now most of the United States change clocks on the second Sunday in March and again on the first Sunday in November.Follow Storm Shield Meteorologist Jason Meyers via the Storm Shield app on Twitter, Facebook, and YouTube.

TORONTO (AP) — The United States has agreed with Canada and Mexico to extend their agreement to keep their border closed to non-essential travel to July 21 during the coronavirus pandemic. Canadian Prime Minister Justin Trudeau said Tuesday's agreement extends the closure by another 30 days. "This is an important decision that will keep people in both of our countries safe,” the prime minister said in his daily press conference. Americans who are returning to the U.S. and Canadians who are returning to Canada are exempted from the border closure.Acting Department of Homeland Security Secretary Chad Wolf issued a statement Tuesday on why extending non-essential travel restrictions with Canada and Mexico was necessary. "The Department of Homeland Security will ensure that the measures taken at our borders will protect America from all threats, including threats against the health and safety of our citizens," Wolf said in the statement. "Based on the success of the existing restrictions and the emergence of additional global COVID-19 hotspots, the Department will continue to limit non-essential travel at our land ports of entry with Canada and Mexico. This extension protects Americans while keeping essential trade and travel flowing as we reopen the American economy. The Department of Homeland Security is in close contact with our Canadian and Mexican counterparts regarding this extension, and they agree on the need to extend their non-essential travel restrictions as well. I look forward to continuing to work with our neighbors to maintain essential trade and travel while protecting the health of our respective citizenry." The Mexican Embassy in the United States said in a series of tweets that the decision came "after reviewing the development of the spread of COVID-19 in both countries." 1829

There’s been a significant bounce back in the U.S. job market, according to the U.S. Bureau of Labor Statistics’ latest monthly unemployment report. In June, 4.8 million people were able to go back to work.Businesses in hospitality and leisure added 2.1 million jobs. Food services and drinking establishments added 1.5 million jobs, while retail saw 740,000 workers return to work.“The job market bounced back pretty strongly in June, but we have to keep everything into perspective,” said Ryan Sweet, an economist and Head of Monetary Policy and Research for Moody’s Analytics.Sweet says compared to where the U.S. was prior to the pandemic, jobs are still down by roughly 15 million.Economists, like Sweet, believe the job rebound seen in June is likely over, and the U.S. job market will likely reflect a lull in July.“The lull, it is unclear how long that will last,” Sweet said. “We are hoping until the end of this year.”As coronavirus cases continue to surge in the U.S., the hope for just a lull dwindles and worry about another decline in employment grows.Companies like United and American airlines are already signaling major job loss could come in the near future. Both companies recently reported they may have to each layoff 25,000 workers. Analysts predict if other airlines have to do the same, the industry could lose up to 250,000 jobs.That’s hundreds of thousands of potential jobs lost in just one industry, and many others are signaling a similar situation.“The ones that I am most nervous about are state and local governments because it seems that there is less urgency for lawmakers to pass fiscal stimulus,” said Sweet. “If we don’t get another round of fiscal stimulus, this lull is going to turn into a contraction.”Congress has been talking for two months about another stimulus package, but there is no clear signal that one will come in time. 1881
