Current Nutritional Trends in Immune and Gut Health

When: Wednesday, 07/18/2018 through Wednesday, 07/18/2018, 10:30 AM - 12:00 PM

Where: McCormick Place - S405AB

Diet influences the immune response of individuals, both systemically and in the gastrointestinal tract (GIT). The effects of various dietary components on immune response continue to be studied and advances made. The effect of immune-active components on immune function can be measured by changes in the quantity and biological activity of numerous immune biomarkers. The impact of dietary interventions and additives (e.g. probiotics) on immune response are a current topic in nutrition research. It is possible to use functional food components to modulate immune response and support systemic and digestive health of the general population.

The symposia will examine this topic from three different perspectives: (1) current research into the immune response of PUFA ingredients in the diet, (2) the science supporting probiotic effects on immune response, and (3) an evaluation of the science supporting commercially available food ingredients affecting systemic and GIT immune response. Inclusion of key ingredients in the diet such as PUFA’s, prebiotic fibers and probiotics have been shown to modulate the immune response both systemically and in the GIT. The key message to be presented is that inclusion of select ingredients in functional foods can have a measurable, beneficial effect on the immune response of generally healthy people.
Next Generation Sequencing Metagenomics Approaches to Probe the Microbiome Throughout the Beef Chain: From Fundamentals to Applications

When: Tuesday, 07/17/2018 through Tuesday, 07/17/2018, 12:30 PM - 02:00 PM

Where: McCormick Place - S404D

This session will explore novel findings and methods used to study the microbial ecology of meat production, specifically, the microbiome during multiple segments of meat production. This includes considerations of pathogenic bacteria, microbial resistance, and spoilage bacteria. Studies of the microbiome are possible due to recent collections of large amounts of microbial sequencing data. This sequencing data may be used for bioinformatic tools to analyze and interpret data to identify and quantify bacterial species. There are, however, several considerations related with sampling and interpretation of this data. In addition to sharing recent results in this area. Speakers will provide background about this emerging approach and the important parameters that must be considered around producing and interpreting microbial ecological data.
Improving Microbial Safety of Fresh Produce: Pilot Plant and Commercial Scaled Studies and Related Agricultural Economic Analysis

When: Wednesday, 07/18/2018 through Wednesday, 07/18/2018, 10:30 AM - 12:00 PM

Where: McCormick Place - N426C

Fresh and fresh-cut produce has been linked to outbreaks resulting from bacterial, viral, and protozoan pathogens infection in the last 20 years. Since 2011, the Food Safety Modernization Act (FSMA) authorized the U.S. Food and Drug Administration (FDA) to issue regulations for fresh produce processors that would require establishment of preventive controls for potential food safety hazards in their products. In addition, United Fresh Produce Association just published a guideline for fresh-cut produce processors to involve three options to prevent cross-contamination during produce washing process including: (1) apply a pathogen surrogate for the microbial hazard and verify that cross-contamination is prevented by the antimicrobial wash; (2) use of antimicrobial sensors and the demonstration that a critical antimicrobial level is maintained during worst-case scenario; and (3) validate the placement of the sensors in the processing equipment. The dynamics of processing conditions applied by various produce growers are more complex than laboratory conditions. Meanwhile, the new FSMA gives small farms and direct-market farms who sell produce locally the option of complying with state regulations; provide the US-FDA with the authority to exempt farms engaged in low or minimal risk processing from new regulatory requirements; reduce unnecessary paperwork and excess regulations required under the preventative control plan; and exempt farmers from extensive traceability and recordkeeping requirements. Therefore, it is crucial to ensure that both industry scale and locally grown fresh produce producers/growers are equipped with scientific pilot plant validated information, which are closer to real-life scenarios. Besides, the most recent USDA-NIFA RFA specifically identifies the development of economic incentives that lead to improved food safety including fresh produce safety as one of its key priorities. The agricultural economic cost-effectiveness analysis will provide direct and early identification of major economic factors that impact the adoption of the pathogen control strategies during fresh produce processing. This session will begin with an overview of key factors affecting bacteria survival and transfer during tomato and leafy green post-harvest washing processing in pilot plants. Following that, an industry scale in-plant validation study of antimicrobial application in various fresh produce processes and the application of pathogen surrogate will be discussed. In addition, a “three-step” washing process to control foodborne pathogens on fresh produce and storage bins in West Virginia local community will be presented. Finally, an analysis of economic feasibility of control strategies to improve microbial safety for fresh produce will conclude the session. The invited speakers include a food technologist, food microbiologist, food industry consultant, and agricultural economist, and represent expertise from the food industry, government research institutions, and academia.
Hot Topics Session: Technological Advances and New Insights into the Emerging Insects as Sustainable Food Ingredients Industry from Farm to Table

Where: McCormick Place - N427ABC

This symposium will highlight the latest in cutting edge research and the state of the new industry developing insects as sustainable food ingredients and a family / suite of new commodities for the food industry (protein isolates and extracts, whole insect based ingredients such as cricket powder, oil, fiber, and bioactives, etc.) We will offer information to stake holders on the latest research and technology development in insect farming, processing, functionality evaluation and product development. We will also provide late breaking cutting edge research on insect genomics and transgenic insect development for newer and improved lines of farm raised insects (crickets, mealworms, etc.) for more efficient delivery of nutrient dense insect based food products and disease resistant insects.
Development of New Pet Food Ingredients: Understanding the Science and Regulations That Lead to Success

When: Tuesday, 07/17/2018 through Tuesday, 07/17/2018, 02:15 PM - 03:45 PM

Where: McCormick Place - S402AB

The opportunity for new ingredients intended to improve the well-being of both companion animals and livestock has been growing rapidly. Marketing advantages have been guiding research into these functional ingredients, however, there must be an understanding of the challenges that come with altering diets and meeting adequate nutritional requirements for the target animal. In addition, novel animal food additives can introduce new analytical challenges that must be overcome in order to ensure safety and consistency of the added ingredient. Finally, regulatory challenges that are unique to animal food need to be appreciated when developing the path forward for new ingredients. There are distinct differences between GRAS and food additives in the need for publicly available data, consensus of opinion on safety, historical and background use, and proprietary position that make choosing the right path critical for success. Equally important is the understanding that dietary supplements do not apply to animal feed and ingredients which are intended to affect structure/function of the body other than having a nutritional impact make the new product fall under the regulatory classification of “new animal drug.” These nutritional, analytical, and regulatory issues will be explored in depth to provide the attendee with a good understanding of the challenges in animal ingredient development.

Shedding Light on Food Safety, Quality, and Nutrition: Opportunities and Challenges With Light-Based Technologies

When: Wednesday, 07/18/2018 through Wednesday, 07/18/2018, 08:30 AM - 10:00 AM

Where: McCormick Place - N426C

The CDC estimates that every year, there are 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths in the United States due to consumption of foods contaminated with pathogens. Therefore, it is necessary to process foods to effectively inactivate these microorganisms to render food safe. Various preservation technologies have been developed and adopted successfully to eliminate or reduce microbial contamination of the food. However, conventional treatments are very highly energy intensive with high capital and operational costs. Most often these processes also result in deterioration of food quality. Therefore, there is a need for alternative processing methods that are simple, cost-effective, have high inactivation efficiencies and yield minimal quality changes. Emerging technologies such as UV light, pulsed light and LED light processing show great promise since they can inactivate the pathogenic microorganisms while preserving the quality of foods.

This session will focus on recent advances in the light-based technologies for microbial decontamination. There has been an increased interest in the applications of light-based technologies such as UV light, pulsed light and LED light for inactivating microorganisms. Typically, these technologies operate in the UV, visible and near-infrared light range. Studies have shown that these technologies can effectively inactivate myriad microorganisms. However, there are several challenges associated with these technologies. The identified speakers are experts in the light-based technologies. They will shed light on the applications and challenges of these technologies. Due to the increased interest in these technologies, a symposium on this topic is highly warranted.

This session is sponsored by Phi Tau Sigma, the honor society of food science and technology.

Three dynamic speakers will approach the question of red meat intake from multiple vantage points. Specifically, the health implications of including red meats in a healthy diet will be discussed. Secondly, the role of red meats and cancer will be explained based on current evidence. Finally, the challenges of limiting livestock production as a means of improving environmental outcomes while maintaining healthful diets for a growing population will be discussed.
New Advancements in Botulinum Neurotoxin Detection Methods: From the Mouse Bioassay to Mass Spectrometry

When: Wednesday, 07/18/2018 through Wednesday, 07/18/2018, 01:15 PM - 02:45 PM

Where: McCormick Place - S404D

Clostridium botulinum neurotoxins continue to be a threat to the global food supply through natural and possibly intentional routes of contamination. Rapid, sensitive, and specific detection of the most potent neurotoxin known, botulinum neurotoxins (BoNTs), is of vital concern to prevent cases of the neuroparalytic disease (botulism). The mouse bioassay is considered the gold standard assay because it a positive result in the test requires all four steps of intoxication, internalization by the host through the small intestine, trafficking of the toxin to the target cell via the blood and lymphatic system, translocation into the target neuronal cell and finally, catalytic activity of the toxin's light chain on SNARE proteins to prevent the release of the neurotransmitter, acetylcholine at the neuromuscular junction. Disadvantages to the mouse bioassay include the ethical concerns of using laboratory animals, the expensive cost, and the time to receive a positive result, which can take up to 4 days for a positive. Functional based assays (e. g. endopeptidase mass spectrometry, cell based and Förster resonance energy transfer) are specific and rely on the biological activity of the botulinum neurotoxin. Immunological and other in vitro assays, such as enzyme linked immunosorbent assays (e. g. DIG-ELISA) cannot discern between active and inactive toxins. This symposium will discuss the current assays used to detect botulinum neurotoxins in food and clinical samples, address their advantages and disadvantages, and highlight the most rapid, sensitive, and specific assays that are being widely adopted to replace existing toxin detection and/or screening methods.
The Future of Food Packaging

When: Wednesday, 07/18/2018 through Wednesday, 07/18/2018, 10:30 AM - 12:00 PM

Where: McCormick Place - S404A

The future of food packaging concerns the consumer packaged food industry as well as business-to-business commerce in the case of food ingredients, as well as shipments of foods in intermediate states of processing for consumers. The future of food packaging relates to how packaging technology will be applied to extend the shelf life of food and decrease food waste while being competitive and meeting business-to-business as well as business-to-consumer needs. Future food packaging must be meet technical needs of a changing food supply, consumers’ buying patterns, and changes in complex supply and value chains. This session will not review past technologies in place; but, instead address emerging, future/pending food packaging technologies related to: sustainable packaging to align with the circular economy, meeting the needed of altering venues such as e-commerce, intelligent packaging to benefit the value chain, active packaging, and package design.

This topic is relevant to food industry professionals looking for innovations, development pipeline context, and competitive advantages, as well as researchers searching for alignment of their research to new packaging technologies. This session is co-sponsored by the Food Science and Technology Honorary Society Phi Tau Sigma.
Whole Genome Sequencing: Overview and Role in Food Safety Systems

When: Wednesday, 07/18/2018 through Wednesday, 07/18/2018, 08:30 AM - 10:00 AM

Where: McCormick Place - S404D

In recent years, whole genome sequencing has emerged as a powerful food safety tool. The unprecedented resolution of whole genome sequencing allows for highly improved characterization and subtyping of microorganisms over methods such as pulsed field gel electrophoresis. This in turn has helped to improve epidemiological investigations of foodborne illnesses by more quickly and accurately linking clinical isolate whole genome sequence subtypes with those of food and environmental isolates. By providing this faster and more accurate link, foodborne illness outbreaks can be resolved in much more timely manner, which therefore helps reduce the number of foodborne illness cases. Consequently, whole genome sequencing has been adopted as a key tool in the repertoire of regulatory and public health agencies such as the FDA, USDA, and CDC for resolution of foodborne illness outbreak investigations and other applications such as monitoring of antimicrobial resistance.

Yet, although these agencies have begun to use whole genome sequencing in these ways, there is still a need for policy development surrounding the technology. As a result, the use of whole genome sequencing in the food industry has been limited. There are many different applications of the technology that would greatly improve food safety management from different areas of the food industry. For instance, whole genome sequencing can be used to identify possible harborage of a bacterium in a food processing facility. It can also be used to tie together isolates that were involved in a beef slaughter "event day." Other uses of next generation sequencing technology that are not directly applied to whole genome sequencing, such as 16S metagenomics, are also important for investigating sources of spoilage and determining the types of microorganisms present at different stages of the process. Yet, due to uncertainty around the regulatory perspective of the use of the technology, the food industry has been reluctant to widely adopt it as a tool in their food safety management systems.

This symposium will discuss an overview of the current technology that is available for performing whole genome sequencing and the current uses of whole genome sequencing by third party laboratories. This will then be followed up by presentations from the meat and produce industries where the use of whole genome sequencing by the members of these industries will be discussed, along with the concerns that still remain for these industries from a regulatory standpoint. Lastly, the session will be rounded out by a presentation on the legal and regulatory concerns on the use of whole genome sequencing, including information on the current landscape of policy development with regard to the technology.
