Backlogs At Smoke Testing Labs Force Washington Wineries To Get Creative – Forbes

As wine regions around the world face the immediate effects of devastating fires, the threat of smoke exposure is of concern. Wildfires and controlled burns generate smoke particulates that could be taken up by the berries and leaves of grapes in nearby vineyards. While the chemical composition of smoke from wood pyrolysis is rather complex, free volatile phenols (VPs) are believed to be the major aroma compounds that confer the smoke exposure characteristics to grapes and wines. In the vineyard, these VPs can permeate the grape skins and rapidly bond with the sugars inside to form molecules called glycosides. Once the grapes are fermented, the acidity in the resulting wine will begin to break these bonds (even after bottling), rendering the phenols volatile and releasing their smoky flavor once again. IEH Analytical Laboratories in Seattle, WA offers expedited volatile phenol testing services to the wine industry.

IEH Acquires Brooks Applied Labs – August 2020

Brooks Applied Laboratories brings extensive capabilities in trace metals and metals speciation to IEH Laboratories & Consulting Group. Toxicological and nutritional properties of a chemical element critically depend on the form in which it occurs in food. Some elements are an essential part of a healthy diet, but others, such as lead, mercury, arsenic  and cadmium, offer no nutritional benefits to humans and are actually toxic.  Local and international regulations require manufacturers to monitor levels of hazardous elements in foodstuffs. In addition, Regulators require food manufacturers and suppliers to label food with ingredients and nutritional information.  As a consequence, trace element speciation, particularly for toxic trace elements such as Arsenic, Chromium, Lead, Mercury and Selenium, and trace element bioavailability is of critical importance to ensure the safety and nutritional quality of raw ingredients and finished products products throughout the food supply chain.

IEH tested supermarket ground beef samples for the presence of E. coli, Listeria and Salmonella for this Inside Edition story.


“CBD seems to be everywhere. It can be found in all kinds of everyday products, from lotions to supplements, as well as dog food. CBD, or cannabidiol, is found in cannabis plants. It doesn’t give the user a high, but it’s being marketed to relieve all kinds of ailments. The CBD products sold often indicate on the label how much of the chemical is contained inside. The products can list anywhere from a few milligrams to a few hundred. Inside Edition wondered if customers are actually getting the amount of the chemical they’re paying for. To find out, we bought some products and sent them off to a lab for testing. We purchased CBD from all types of retailers, including upscale stores and products sold online. The results were surprising, as lab tests found three of the nine products we purchased contained less CBD than was advertised.”

Researchers confirm pathogens in raw wheat, urge cautious use of raw flour – Food Safety News

“Research data published this month in the Journal of Food Protection by a team of researchers from ConAgra Inc., WhiteWave Foods Co., and the third-party IEH Laboratories & Consulting Group documents dozens of kinds of bacteria in raw wheat, including many strains of E. coli and Salmonella…“This is a complicated issue. In the absence of FDA dictating a remedy, it takes an industry years to respond. The first outbreak of E. coli O157 for the beef industry was in 1982. It took 20 years, until December of 2002, and regulatory action by FSIS for the industry to effectively address the issue,” Mansour Samadpour told Food Safety News. “While we fully expect the baking process to eliminate the pathogens such as Salmonella, (enterohemorrhagic E. coli) and Listeria, cross contamination and consumption of raw dough can and will result in a public health impact.””

9 People Who Are Changing The Future Of Food – Fast Company Profile on Mansour Samadpour

“It’s better to set up systems properly in the beginning, rather than have to deal with an outbreak. Food safety is a moral obligation.”

7 things to know about our food system – CNN Money

“Mansour Samadpour runs IEH Laboratories, one of the largest private food testing facilities in the nation. Companies hire him to test their food and make sure it’s safe for the consumer. He believes much of the current testing is too infrequent and small in scale. “We call that faith-based food safety,” he says. Why do companies resist more testing? If more was done at the retail level, it would “always result in recalls,” Samadpour says, because they find pathogens in the food so often. But he also insists that some companies “are doing everything that they can” with regard to food safety.”

One person dying of food borne illness is ‘one too many’ – Mansour Samadpour interview on CNN Money

People need to understand what they are eating, where it was grown. You buy a bag of lettuce, where was it grown? Is the product from California? Arizona? Came from south of the border somewhere? The country of origin of the food we buy is extremely important. Let’s say you’re looking to travel to a country, they tell you don’t eat salad, don’t drink the water. And then you find out that the salad you buy comes from there. Then you say, okay, what are they thinking? Anything grown out in a field will have some amount of microbial contamination. What the green industry is trying to do is remove as much of the contamination as possible, but that’s not universal.

We Have Terrible News For Anyone Who Eats Chicken – Mother Jones

“One of the US Department of Agriculture’s main tasks is to ensure that the nation’s meat supply is safe. But according to a new peer-reviewed study from the department’s own researchers, the USDA’s process for monitoring salmonella contamination on chicken—by far the most-consumed US meat—may be flawed.”

“The solution is pretty clear, Samadpour told me. Instead of testing whole carcasses just after they’ve been bathed in antimicrobials, while they’re still in the middle of the processing line, the tests should happen at the end of the processing line, when the carcasses have been cut up and are ready for packaging. He said Big Chicken could learn something from the beef industry, which began testing its finished products in that manner for a virulent E. coli strain called O157:H7 in the 1990s: Rates of poisoning from that often-deadly bacteria have plunged since.”

Some Pre-Grated Parmesan Contains Additive Derived From Wood Pulp, Investigation Finds – Inside Edition

Private Eyes in the Grocery Aisles – The New York Times

Business is booming — partly because IEH clients consider testing to be a gatekeeper defense in a multitiered food economy without borders. “We’re a lot more concerned about imports,” Mr. Samadpour says, because of “lack of accountability, lack of infrastructure, lack of a culture of food safety.” He says episodes like the 2008 discovery of the toxic chemical melamine in infant formula from China have contributed to a gradual shift in food manufacturers’ attitudes toward imports.

IEH welcomes Dr. Donald Zink – IEH Press Release

Putting Salad Bar Safety to the Test – Food Safety News

Besides [E. coli, Listeria or Salmonella], the station reported that the lab tested for the number of microbes in one gram of food, and those results weren’t negative. In fact, the leafy green samples all had more than 1 million colony-forming units per gram (CFU/g) of microbes. Dr. Mansour Samadpour, the CEO of IEH Laboratories, noted that leafy greens are not only raw but have a larger surface area than some other food items.

Chipotle Hires Safety Consultants to Cope With Health Scare – Bloomberg

After shutting restaurants in Seattle and Portland, Oregon, Chipotle is doing a deep cleaning of the locations, the company said in a statement Tuesday. Twelve people in the Portland area and 25 in Washington state became ill after eating at Chipotle restaurants, according to health officials in the two states. The company is working with Seattle-based IEH Laboratories & Consulting Group to resolve the matter, as well as conducting environmental testing in restaurants and distribution centers. Chipotle also is replacing all the food in the closed locations.

Chipotle Installing New Food Safety Protocols From the Ground Up – Food Safety News

IEH Laboratories and Consulting Group is in. Led by Seattle’s Dr. Mansour Samadpour, IEH brings its own significant credibility to Chipotle’s table. Known to many within the food safety community simply as “Mansour,” the microbiologist says he’s going to deliver “a more robust food safety program to ensure the highest level of safety and the best quality of all meals served at Chipotle.”

Meet the Man Who Fights Rampant Food Fraud – Eater

Samadpour’s company — which has over 1,500 employees across 116 labs — tests everything from whether or not a box of raspberries are actually organic or if a piece of “wild-caught” fish is actually wild, or the species listed on the label. He notes that fish are often mislabeled because once they have been filleted, there’s no way of identifying the specifies without a DNA test. Other products that are commonly found in restaurants like olive oil, are also often fraudulent.

Mansour to the Rescue – Food Safety News

Mansour said Chipotle adopted his food safety plan for the 1,900-plus restaurants of the Mexican fast-casual food chain “without any modification.” He promised to eliminate or mitigate “risk to a level of near zero and will establish Chipotle as the industry leader in this area.” Whether naming a food safety czar marks the beginning of a turnaround for Chipotle remains to be seen. However, the strung-out E. coli outbreak is pounding the Denver-based franchise known as much for its politics as its food.

Lesson from Blue Bell recall: producers should ‘assume food is not safe’ – The Guardian

“Outbreaks that last this long are more common than one might think, said Samadpour. They occur whenever the investigators cannot connect the dots and are not able to find the source of the outbreak, which means that the contaminated product continues to be sold. “By the time people are sick, it’s too late,” he said. Companies should be diligent in their sampling and testing. “If you are producing food, let’s not assume that the food is safe until proven otherwise. Let’s just assume that the food is not safe until proven otherwise.””

Third-deadliest U.S. food outbreak was preventable, experts say  – CNN

“Too often we are willing to send paratroopers after something goes wrong and — you know, we kill so many people,” he (Mansour Samadpour) said. “But the question is: Where were these guys before? Why should anyone be allowed to have a processing plant without the required amount of expertise, without having the food safety systems in place, (to) produce food and send into the chain of commerce? We have had failures at multiple levels.” 


Tests find 80% of chickens in Seattle-area groceries carry pathogens – Seattle Times

“The U.S. Department of Agriculture monitors the levels of some bacteria in poultry. Effective in July, the agency is tightening its rules. Processors will have to ensure that no more than 7.5 percent of raw chickens are contaminated with salmonella and no more than 10.4 percent with campylobacter. The 100 chickens tested in Seattle came from multiple producers in Washington, California, and other states. But collectively, the birds would not have passed the new standards: 65 percent were contaminated with campylobacter and 19 percent with salmonella. More than 40 percent of the samples tested positive for Staphylococcus aureus, which is not regulated by USDA.”

Seattle Lab Finds Tainted Grocery Store Chickens – Food Safety News

“Mansour Samadpour, the nationally known food scientist who runs the Institute for Environmental Health (IEH), tested 100 retail chickens at the request of Marler Clark, the food-safety law firm also based in Seattle.”


Food-Safety Lawyer Puts His Money Where Your Mouth Is – Marler Clark

“In early 2008, Marler began talking seriously to Samadpour, who heads the Seattle-based Institute for Environmental Health, about sampling meat in groceries to see whether there was widespread contamination… A deal was struck, a testing protocol developed and Samadpour told his labs across the country to begin buying 5,000 of the large, plastic-sealed packages of ground beef and analyzing the meat inside for all strains of E. coli… Samadpour briefed the USDA scientists three times and shared the findings with the National Meat Association and American Meat Institute. Samadpour found a low percentage of the meat was contaminated by the non-O157 strains of E. coli — about 2 percent. But since American consumers eat billions of pounds of ground beef each year, that 2 percent means millions of pounds of potentially dangerous meat are being eaten.”


Food Problems Elude Private Inspectors – The New York Times

““The contributions of third-party audits to food safety is the same as the contribution of mail-order diploma mills to education,” said Mansour Samadpour, a Seattle consultant who has worked with companies nationwide to improve food safety.”

The Burger That Shattered Her Life – The New York Times

“Dr. Samadpour, the laboratory owner, has said that “we can make hamburger safe,” but that in addition to enhanced testing, it will take an aggressive use of measures like meat rinses and safety audits by qualified experts.”

Keep Your Meat Safe From E. coli – abc NEWS

“A “Good Morning America” investigation found that what is generally thought to be a simple meal — the classic American burger — can be much more complex. For its investigation, “Good Morning America” purchased six packages of 100 percent ground beef patties from major supermarket chains in Seattle and took the patties to IEH Laboratories, one of the meat industry’s largest independent testing labs. “We isolate DNA from each,” said Mansour Samadpour of IEH. “We looked at eight pieces of meat from each hamburger patty.” When the results came back, the lab reported at least four cows had been found in each patty — and sometimes as many as eight.”


Spinach E. coli Outbreak Raises Food Safety Questions – Marler Blog

“We have the safest food supply on the planet,” said Samadpour, of IEH Laboratories. After the outbreak in spinach, the affected companies hired him to detect and prevent E. coli. “This was an anomaly. Something happened at the farm level. And there have been a lot of extra steps these companies are taking to make sure this product is safe.” Samadpour says Natural Selection foods now takes the unprecedented step of testing all its raw materials before they’re processed. He says safety is now rapidly improving. “These are watershed events in food safety – this is when the industry realizes there may be a problem they did not anticipate before.”
