The Bacteria in Beef That ‘Don’t Behave’

Tuesday, June 26th, 2012

BY DAVID DESPAIN

Beef producers have become quite successful at detecting and preventing contamination of E. coli 0157:h7 in their raw beef products—that’s thanks to years of experience after the Shiga toxin-producing bacterial strain (STEC) was first declared as an adulterant in raw beef in 1994.

However, the USDA Food Safety and Inspection Service (FSIS) has now expanded the adulterant list to include six non-0157 strains (026, 045, 0103, 0111, 0121, and 0145). The new rule had producers and scientists at the IFT Annual Meeting on Tuesday, June 26, warning that these bacteria “don’t behave” like you’d want them to.

“With 0157, we’ve had years and years of testing. We haven’t had those years of experience in the lab with these,” said food safety and public health professor Mindy Brashears of Texas Tech University.

The rule, in place as of June 4, 2012, (an extension from March 5, 2012), was in response to an October 2009 citizen’s petition. According to research microbiologist Christopher Sommers, the petition came after recent outbreaks and a CDC study that showed that these “big six” accounted for more than 70% of non-0157 STEC infections from 1983 to 2002.

A couple of companies—Costco and Beef Products Inc. (BPI)—already have food safety systems in place for non-0157 STEC strains. Director of food safety and quality assurance at BPI, Craig Letch, said that the company developed a system using “robust sampling” (n=167) and has spent well “over a million dollars” in outsourcing 100% of the testing for non-0157 STEC strains. Costco Wholesale’s program for testing for non-0157 STEC strains has been in place since June 2010, according to director of food safety and quality assurance Christine Summers.

“Obviously, we don’t want to make any of our customers sick,” she said, noting that the company produces about 160 million pounds of ground beef annually.

However, she added that there are problems with the rule. “There is a diversity of STECS. It would be beneficial to identify the virulence genes that cause human illness. Knowledge needs to be gathered.”

Despite challenges, Brashears is optimistic that the methodologies are sure to continue to improve as testing progresses and more baseline data is collected. Ultimately, she said, interventions pre- and post-harvest will be key to reducing STECs and protecting the beef supply. 

The FSIS has issued methodology for detecting the “big six” at www.fsis.usda.gov/PDF/mlg_5b_02.pdf.

IFT Kicks Off Campaign to Counter Misconceptions about Food Science

Tuesday, June 26th, 2012

The Institute of Food Technologists (IFT) today launched a new public education  campaign called ”A World Without Food Science” (www.worldwithoutfoodscience.org) that will aim to generate greater awareness of the role food science plays in ensuring a nutritious, safe and abundant food supply. The campaign is a multimedia, national initiative featuring a series of videos that highlight how food science has responded to major food issues and provided positive solutions on a global scale.

The overarching kick-off video, unveiled during the keynote session at IFT’s Annual Meeting & Food Expo in Las Vegas, accurately depicts what a grocery store would be like without the existence of food science. The black and white footage shows empty shelves, rotten fruit, insect-infested grain and spoiled meat to show the realities of a world without food science. The scene changes to color when the voiceover explains how dedicated food science professionals make it possible to have food that is safe, flavorful and nutritious. The concepts of the video are based on an IFT scientific review titled “Feeding the World Today and Tomorrow: The Importance of Food Science and Technology” published in the peer-reviewed journal, Comprehensive Reviews in Food Science and Food Safety.

The campaign also includes five separate video segments that feature interviews with experts from various food science disciplines to show the positive impact of food science on the public. The first two video segments of the series were presented during the keynote address at the IFT’s Annual Meeting & Food Expo. The first video highlights the challenges surrounding availability of food and how we will need to feed approximately 9 billion people by 2050. The second video focuses on food safety and the important role of food science in ensuring that the food we eat is safe.

“As a scientific society, education is at the core of our mission as we advance the science of food. It’s especially important for the public to understand where their food comes from,” said IFT President Roger Clemens, DrPh. “This campaign tells the story of food science in a new visual way so that consumers understand the role of food science in their daily lives.”

In addition to consumer education, another goal of this campaign is to reach and inspire students to pursue food science careers. Food science incorporates concepts from many different fields including microbiology, chemical engineering, biochemistry and more. The ever-expanding field of food science encompasses a wide range of careers in areas such as food production and processing, quality assurance and control, food product development, food science research, and regulation and enforcement of food laws. IFT.org has information on becoming a food scientist, as well as lesson plans and activities for teachers.  IFT also produced the Day in the Life of Food Scientist videos to help people understand what it’s like to walk in the shoes of a NASA food scientist, a product developer at Disney Consumer Products, and a food packaging professional at a multinational food packaging and processing company.

As part of the World Without Food Science campaign, three more videos will be released within the year. Topics include Nutrition, Environmentally Responsible Food Production, and Developing Food Products for Specific Populations. Each video will be distributed nationwide and featured along with facts and additional resources on www.worldwithoutfoodscience.org. The videos complement IFT Food Facts, a multimedia website created to show the practical applications of food science for consumers, such as food safety in the farmer’s market, how to store leftovers and understanding expiration dates. For more information, please visit iftfoodfacts.org for more information.

This video campaign was produced thanks to funding from the following IFT Divisions—Product Development, Quality Assurance, Citrus, Food Microbiology, Nutraceuticals, and Refrigerated & Frozen Foods.

Antimicrobial Packaging with Biopolymers May Solve Food Safety Issues

Tuesday, June 26th, 2012

Recently, recalls and outbreaks of cantaloupe, tomato, shell egg, and ground meat due to foodborne pathogen contamination have highlighted the need for effective decontamination methods to ensure the safety of foods. Foodborne illness poses a $77+ billion economic burden in the United States annually. As an additional hurdle to non-thermal processes, antimicrobial packaging can play an important role in reducing the risk of pathogen contamination, as well as in extending the shelf life of minimally processed foods. Currently, food applications of antimicrobial packaging systems are limited due to the availability of suitable antimicrobials, new polymer materials, regulatory concerns, and appropriate testing methods. Thanks to concerns about the environment and sustainability, it is critical to design packaging products that utilize renewable resources while providing consumers a better package for protecting and dispensing the foods they buy.

Session 096 Development of Antimicrobial Packaging with Biopolymers to Solve Food Safety Issues will take place on Wednesday morning from 8:30 a.m. to 10:00 a.m. in Room N115. The symposium will focus on the development and application of biopolymers in antimicrobial packaging that can be used for reducing or inhibiting foodborne pathogens. The speakers will address current problems and challenges; discuss the different approaches to development of antimicrobial packaging systems with biopolymers; present the physical, mechanical, and antimicrobial properties of packaging materials; demonstrate their applications in various foods; and propose future research directions and collaborations in this research area.

Advancing the Safety of Fresh Produce

Monday, June 25th, 2012

Lettuce in the FieldSince 2000, the U.S. National Integrated Food Safety Initiative (NIFSI), a competitive grants program, has awarded approximately 300 grants to fund applied research using an integrated approach to solve food safety problems over the farm-to-fork continuum. In 2006, the Special Emphasis Grants was introduced to the program in order to increase funding for critical food safety issues as they arise, and in 2007 the “Improving the Safety of Fresh and Fresh-Cut Fruits and Vegetables” Special Emphasis area was launched, which has remained because of the many issues the food industry faces with produce safety.

NIFSI has funded seven produce safety special emphasis projects since its inception for a total of $11.5 million. They are focused on a variety of pathogens and viruses and the development of interventions and trainings targeted towards farmers, processors, retailers, and consumers. Session 022 “Improving the Safety of Fresh Produce: An Integrated Approach” will provide information on the major outcomes and impacts of several projects that have been funded through this funding stream as provided by the project directors for individual projects.

Jodi Williams, USDA National Institute of Food and Agriculture, will give attendees an overview of the successes and accomplishments of grants program over its 12-year lifespan thus far.

Michael P. Doyle, Univ. of Georgia, will delve in and specifically discuss a research project that was initiated in 2007 to cover both production and processing elements to improve the safety of leafy green products.

Following Doyle, Jeffrey LeJeune, Ohio State Univ., will discuss another research project that looked specifically at how to identify farm management practices to reduce pathogenic contamination and how to get farmers to adopt such methods.

Finally, Larry Goodridge, Colorado State Univ., examines how index organism testing can be used to predict Salmonella contamination in a greenhouse tomato operation.

With the 2010 Dietary Guidelines for Americans stressing the importance of eating fresh fruits and veggies, the research being done to keep produce pathogen-free is vital. Attend session 022 on Tuesday, June 25, 10:30 a.m.–12:00 p.m. in room N113 to learn more about this research.

Nanotechnology Moves Forward

Friday, May 18th, 2012

In April, the U.S. Food and Drug Administration (FDA) issued a draft guidance document that addresses the use of nanotechnology by the food industry. Nanotechnology is an evolving technology that allows scientists to create, explore, and manipulate materials on a scale measured in nanometers—particles so small that they can’t be seen with a regular microscope. There is great potential to impact the food and agriculture sector with on-going research and development in many areas. Public interest in nanotechnology as it relates to food has significantly increased in recent years. Particular interest has focused on application discoveries, potential safety implications, and regulatory oversight. Here are some of this year’s sessions that will focus on different aspects of nanotechnology:

  • Nanotechnology and the Food System (Session 006): Jozef Kokini of the Univ. of Illinois will provide an introduction to the methods, tools, and applications of nanotechnology. Rickey Yada of the Univ. of Guelph will then discuss nanotechnology programs at universities and the need for educating consumers about nanotechnology.

Scientists Say Gulf Seafood Is Safe to Eat

Monday, June 13th, 2011

by Mary Ellen Kuhn

A little over a year after the devastating oil spill in the Gulf of Mexico, government regulators with the National Oceanic and Atmospheric Administration (NOAA) and the Food and Drug Administration (FDA) have determined that seafood from the gulf is safe for human consumption.  

“The bottom line is that there is an extensive amount of data that supports the statement that gulf seafood is safe to eat,” said Calvin Walker, a scientist with NOAA, who made the statement at a press conference on Monday, June 13, during the 2011 IFT Annual Meeting & Food Expo in New Orleans.

NOAA and FDA teamed up to test seafood for oil contaminants and chemical dispersants used to break up the oil that flowed into the gulf. The agencies focused testing on two compounds—Polycyclic Aromatic Hydrocarbons (PAHs) from the oil and Dioctyl Sodium Sulfosuccinate (DOSS) from the dispersants.

The agencies broke up the affected area (about 37% of the Gulf of Mexico) into 30-mile grids and systematically conducted tests on samples drawn from each grid. During the testing process, thousands of samples were collected and tested for contaminants using both sensory and chemical analysis.

At this point, said Walker, all samples have passed the established testing protocols; levels of contaminants were routinely found to be 100 to 1,000 times below any levels of concern. All federal waters and 99% of the state waters have been reopened for seafood harvesting. NOAA is wrapping up the post-opening surveillance process of follow-up testing.

Ensuring Food Safety after a Nuclear Disaster

Monday, June 13th, 2011

by Karen Nachay

Session 116 speakersEnvironmental accidents do affect the food supply and consumer perceptions of food safety, but speed, consistency, and communication are keys to responding to food safety issues, reported Ronald Klein, President of the Association of Food and Drug Officials. He and other experts were on hand to provide information about addressing food safety concerns arising from radioactivity in the late-breaking session “Food after Fukushima: Responding to Radioactive Material as a Foodborne Contaminant.”

Klein, who is with the Alaska Dept. of Environmental Conservation, Anchorage, Alaska, explained to the audience how Alaskan officials worked to determine risk and ensure the safety of food in the aftermath of the earthquake and tsunami in northern Japan and the resulting nuclear meltdown at the Fukushima Daiichi nuclear facility. There was immediate reaction to concerns of radioactivity in foods from consumers and officials in Alaska and around the world. Alaska has plenty at stake: Its seafood industry is a significant segment of its economy and its wild foods like birds, marine and terrestrial mammals, and marine vegetation provide subsistence to many people who do not have access to markets. Alaskan officials partnered with the U.S. Food and Drug Administration and other federal agencies to coordinate environmental health evaluating activities and determine risk assessment, said Klein. Analysis of the data, including data from exposure assessment, toxicity assessment, and risk characterization has shown that radiation release from Fukushima does not pose a risk to fisheries, wild foods, and human health.

Even though Klein and Patricia Hansen from the FDA said that results of their organizations extensive research show that consumers can have confidence in the safety of Alaskan seafood and FDA-regulated foods from Japan, Aurora Saulo, Extension Specialist in Food Technology, University of Hawaii at Manoa, Honolulu, said that results of research she conducted show that most of the consumers who were surveyed for the study will not purchase food products imported from Japan and that their emotions drive the decisions in purchasing these products.

Finally, Kirk Kealy, Director of Raw Material & Supplier Safety, Pepsico, gave the perspective of a large, multinational food company in dealing with such a crisis. In addition to working with U.S. and Japanese officials and crafting a consistent message for consumers and the media, Pepsico had to verify the safety and assess risk of the raw materials imported from Japan and determine possible disruptions to the supply chain if any of these raw materials cannot be used.

Communicating Food Safety Issues in a Global Society

Sunday, June 12th, 2011

by Karen Nachay

Patrick Wall, Beacon Lecturer, June 12, 2011Outbreaks are not due to bad luck, they are due to bad management, explained Patrick G. Wall, Professor of Public Health at the University College Dublin and one of the Institute of Food Technologists’ inaugural Beacon Lecturers.

During the last 25 years many high profile food scares and outbreaks have occurred in the European Union that have eroded consumer confidence in the safety of the food supply and the regulators charged with overseeing food safety issues. As a result, a series of reforms to EU food safety policies and changes to the regulatory environment were established, including reforming EU food laws, creating the European Food Safety Authority (EFSA) to centralize risk assessment, and establishing a food and veterinary office to audit systems and establish standards for food products within and outside the EU. Wall explained in his presentation, “Reform of Food Safety Control in the EU: Are there Lessons for the USA?”, that despite the EU’s efforts in reforming how it addresses food safety, especially with creating the EFSA, challenges still remain in the global food market.

Patrick WallOne challenge Wall discussed in particular was communicating to the consumer in an era of a 24/7 news cycle increasingly dominated by social media and the blogosphere. When a food safety issue arises, media demand answers immediately, which can be burdensome to the regulators dedicating their time and resources to determining the cause of an outbreak. There is also disconnect between consumers and modern food production systems meaning people do not understand where their food comes from, said Wall. Scientists, regulators, and company officials should keep in mind that communication is a two-way process: They should answer questions as well as ask of others what should be addressed, added Wall.

Clemens to Food Scientists: Make a Difference

Saturday, June 11th, 2011

by Mary Ellen Kuhn

Roger ClemensSpeaking Saturday night, June 11, at the Awards Celebration, IFT President-Elect Roger Clemens called on food scientists to help build a better, more nutritious food supply—for consumers in the United States and throughout the world.

“Our mission to supply safe, abundant nutritional food should compel us to develop ideas and strategies to reconcile the U.S. food supply with the Dietary Guidelines for Americans,” said Clemens.

“There are many products that we can develop using whole grains, less sugar, and seasonings other than salt, while assuring a safe and nutritious food supply. Consumer demand is moving away from shelf-stable products, so perhaps we need to reduce our focus on extending shelf life and allocate more attention to maintaining freshness,” he suggested.

As a member of the 2010 Dietary Guidelines Advisory Committee, Clemens was instrumental in supplying science-based recommendations to help shape the guidelines.

“As scientists, we have significant roles to play here,” said Clemens. For example, he pointed out that “we have the opportunity to use science to help bridge the gap between what the Dietary Guidelines recommend and the amount of fresh produce available. We can enhance existing technologies such as vertical farming, hydroponics, and aeroponics or develop new ones to increase our capacity to grow, harvest, and deliver fresh produce.”

Clemens also turned his attention to the state of Americans’ diet and health, noting that there has been an “alarming increase in the number of people with health problems linked to poor dietary choices and lifestyles.”

While the basic approach to a healthier lifestyle is fairly straightforward—eating well, maintaining a healthy weight, and getting adequate exercise—the process of developing dietary recommendations that work for everyone can be complicated. Clemens noted, for example, that “if consumers skip or limit eggs, milk, and butter to avoid saturated fat and cholesterol, they end up with insufficient intakes of choline and vitamin D and numerous other nutrients. … Those consequences could contribute to significant public health issues, particularly among populations at risk.”

Clemens also raised another major challenge confronting those charged with improving Americans’ collective public health. “Healthy food is not nutritious unless it is eaten,” he said. “Clearly, getting consumers to make healthier food choices requires more than issuing new recommendations every five years, putting up a website, and placing healthier choices on the shelves of supermarkets.”

To this end, he noted, “as a follow-up to the release of the Dietary Guidelines, IFT has recommended that we initiate a multi-disciplinary dialogue among key stakeholders from academia, government, and industry, to identify potentially effective interventions to enhance short- and long-term weight management, better understand what drives food behaviors and behavioral economics, and assess the impact of time allocation and constraints as related to food choices.”

Clemens brought his remarks to a close with words of thanks and tribute to the members of IFT. “You membership and volunteerism ensure the strength and relevancy of this organization,” he said. “Our collective expertise makes us the premier authority in food science and technology. Our knowledge makes us the best individuals to ensure that our food resources are capable of meeting current and future Dietary Guidelines, and that we continue to provide a safe and abundant food supply worldwide.”

Prestigious Speakers Offer Unique Perspectives on Food Science

Saturday, June 11th, 2011

by Toni Tarver

New this year at the IFT Annual Meeting is the Beacon Lecturer series. Two sessions will be led by two prestigious individuals who use their extensive experience and knowledge to dispense provocative opinions and cutting-edge strategies in the fields of science and technology. The two presenters for the Beacon Lecture Series are Patrick Wall and Regina M. Benjamin.

Patrick WallPatrick Wall is world-renowned for his contributions to consumer protection and food safety. Wall will be speaking on Sunday, June 12 at 4 p.m. He is an associate professor at the University College Dublin’s School of Public Health and Population Sciences. In addition to his professorial duties, Wall is the leader of a significant research project on the best approaches to risk and benefit communication within the European Union. Also, he is Chairman of the Advisory Body for the Delivery of Official Controls at the United Kingdom’s Food Standards Agency and is trained as both a veterinary surgeon and a medical doctor. Wall’s research covers foodborne illnesses and other diseases related to consumer behavior or lifestyle choices.

Regina BenjaminRegina M. Benjamin is the Surgeon General of the United States. Benjamin will be speaking on Monday, June 13 at 4 p.m. In her capacity as Surgeon General, she provides science-based wisdom on the best ways to improve the health of U.S. citizens and directs 6,500 uniformed health officers serving in global locations, working to accomplish the same. Prior to accepting her current post, Benjamin was Associate Dean at the University of South Alabama College of Medicine and Chair of the Federation of State Medical Boards of the United States. She founded the Bayou La Batre Rural Health Clinic in 1990 to provide much-needed medical services to an underserved rural fishing village and was the first physician under the age of 40 to be elected to the board of trustees of the American Medical Association. In 2002, she was appointed President of the State of Alabama Medical Association, making her the first black female president of a state medical society in the United States.

Dr. Benjamin has frequently referred to the preventable illnesses that have plagued her family, including the death of her father from complications due to diabetes and high blood pressure. “I cannot change my family’s past, but I can be a voice to improve our nation’s health for the future,” she has said. Benjamin has thus placed great emphasis on the importance of healthy dietary options as the solution to health problems linked to poor diets and overconsumption.

Both speakers will offer different perspectives on food and health, perhaps contradicting the opinions and philosophies of food scientists and technologists. Opposing viewpoints are part of what makes these lectures alluring and provocative.

Analyzing the Safety of Seafood Following the Gulf Oil Spill

Saturday, June 11th, 2011

Due to the size and persistence of the oil spill in the Gulf of Mexico following the Deepwater Horizon explosion, the methods for testing the safety of the affected seafood were inadequate and new protocols had to be designed on-the-fly, according to presenters at a Saturday morning IFT Pre-Annual Meeting Short Course on Evaluating the Safety of Gulf Seafood: Programs and Analytical Techniques in the Aftermath of the Deepwater Horizon Spill.

Steven Wilson demonstrates sensory testing of seafood at the Pascagoula laboratory.

Steven Wilson, Chief Quality Officer of the Seafood Inspection Program for the U.S. Dept. of Commerce, discussed Management Decisions for Sensory Analysis in an Emergency Environment. Scientists want to collect data, analyze it, and collect more data to get a total picture, said Wilson. In contrast, food safety professionals have to make “yes” or “no” decisions with some level of risk. The latter mindset was critical in establishing protocol for reopening areas for fishing and seafood harvesting following the gulf oil spill.

Sensory analysis became the standard test for reopening various areas; chemical analyses were also employed. At one point, nearly 40% of the Gulf of Mexico was closed to fishing, noted Wilson. Initially, the sampling program targeted 30 specifies of fish and shellfish. But it was quickly determined that the volume of samples would overwhelm the testing laboratory and sensory panelists. Instead, the sampling program focused on top, middle, and bottom feeders through the use of nets and line trawling. Protocols were developed for sample size, storage, and chain of custody.

The existing protocol called for wrapping a sample of the fish in aluminum foil on the fishing vessel and sending it to the laboratory in Pascagoula, Miss. But due to the hot temperatures in the region, many samples were showing up in the lab in a highly decomposed state. New protocols were put in place, treating the fish as if it were a commercial catch. Wilson told an amusing story of how one fishing vessel called to ask about how it should wrap a 300-lb bluefin tuna in foil.

Another challenge was training the sensory panelists. Due to the burning of the oil and the resulting odor and potential contamination in the area, it was decided that training should take place at a laboratory in Gloucester, Mass. The actual sensory testing was done at the laboratory in Pascagoula. Panelists analyzed for raw odor, cooked odor, and cooked flavor.

Samples were spiked with oil and dispersants as a QC check. This was done sparingly due to the limited availability of the seafood supply in the gulf. Even so, the testers went through about 6 million lbs of purchased seafood in two months.

It’s quite common in sensory analysis to blend samples. But this protocol was quickly abandoned with oysters as the product produced a near-gag reflex, explained Wilson.

Utilizing Nanotechnology to Enhance Food Safety

Saturday, June 11th, 2011

In recent years, various nanotechnology-based approaches have been explored to provide novel solutions to food safety challenges. Such solutions include nanoscale delivery of antimicrobials, novel nano-biomaterials and delivery vehicles, food processing surface modification at the nanoscale level, food polymer packaging, and interactions with food matrices.

On Sunday morning from 10:30 am–12:00 pm in Room 383, Session 017 Nanotechnology-Enabled Food Safety Interventions will present a comprehensive review of nanotechnology-based food safety intervention technologies. Four active research leaders in the field with diverse and complementary scientific approaches will discuss the newest and latest developments.
