Abstract and Figures

A globalized food trade, extensive production and complex supply chains are contributing toward an increased number of microbiological food safety outbreaks. Moreover, the volume of international food trade has increased to become very large. All of these factors are putting pressure on the food companies to meet global demand in order to be competitive. This scenario could force manufacturers to be lenient toward food safety control intentionally, or unintentionally, and result in a major foodborne outbreak that causes health problems and economic loss. The estimated cost of food safety incidents for the economy of the United States is around $7 billion per year which comes from notifying consumers, removing food from shelves, and paying damages as a result of lawsuits. Most other countries similarly have economic losses. Much of these losses represent lost markets, loss of consumer demand, litigation and company closures.

Abstract: A globalized food trade, extensive production and complex supply chains are
contributing toward an increased number of microbiological food safety outbreaks.
Moreover, the volume of international food trade has increased to become very large.
All of these factors are putting pressure on the food companies to meet global demand in
order to be competitive. This scenario could force manufacturers to be lenient toward food
safety control intentionally, or unintentionally, and result in a major foodborne outbreak
that causes health problems and economic loss. The estimated cost of food safety incidents
for the economy of the United States is around $7 billion per year which comes from
notifying consumers, removing food from shelves, and paying damages as a result of
lawsuits. Most other countries similarly have economic losses. Much of these losses
represent lost markets, loss of consumer demand, litigation and company closures.
Concrete steps are needed to improve safety of foods produced for local or overseas
markets to avoid unexpected food scandals and economic losses.

1. Introduction
The potential impact of food safety outbreaks on a food business or a company can be devastating.
A single event of a foodborne disease outbreak can bring unimaginable economic losses [1].
An increase in the globalized food trade in recent years, extensive production often involving many
sites and a complex supply chain all contribute toward an increased number of microbiological food

safety outbreaks. Moreover, the volume of international food trade increases yearly. These are the
reasons behind huge pressure on the food companies to be competitive globally and sometimes could
result in a relaxed attitude toward food safety control by the producers, eventually causing a food
scandal. Economic analysis of food safety related costs showed that it is much cheaper for a producer
to invest in preventing events of foodborne outbreaks than the cost after an event [2]. There are many
reasons for these companies to improve the safety of their products:
To avoid financial loss due to loss of business.
To avoid unexpected expenses on recalls, disposal, and penalties.
To avoid legal costs due to foodborne outbreaks.
To maintain the reputation of the company.
To maintain consumer’s confidence and loyalty.
To meet government regulations and standards.
To ensure supply of safe food products.
To increase sales and exports.
Food safety is important for the people’s general health and daily life, economic development, and
social stability, and the government’s and country’s image [3]. For example recent Clostridium
contamination of whey protein products put the producer company at the centre of a global food safety
scare [4]. The company management and government authorities are trying their best to protect the
overall reputation of their global business. This incident highlights a strong need for government
regulatory agencies to tackle the challenges in food safety. It is understandable that the private sector’s
prime target is to increase profits relative to costs; food safety protection for consumers is dependent
on strong government regulations [5]. Therefore, it is reasonable to expect a more reactive than
preventative approach from regulators on major food safety scandals rather than addressing the
underlying problems. This article will emphasize the economic importance of improved food safety for
the companies using some examples of outbreaks.
2. Key Food Safety Incidents and Economic Losses
An estimated annual 300,000 hospitalizations and 5000 deaths in the U.S. alone are related to
food-borne illnesses; which gives us an idea of the likely economic implications. The cost estimate of
food safety incidents to the U.S. economy is around $7 billion which comes from notifying consumers,
removing food from shelves, and paying damages as a result of lawsuits. Table 1 lists some of the
expensive food outbreaks in the world.
Two recent food-contamination cases which occurred in August 2013 reiterate concerns about the
effects of globalization on the food supply [6]. Both outbreaks were linked to international food trade.
The first outbreak was the Cyclospora parasite in Iowa and Nebraska which originated in a salad mix
produced in Mexico by a subsidiary of the Californian based Taylor Farms. The parasite can cause
severe stomach illness. This outbreak led to the announcement by the company that it was voluntarily
suspending shipments of salad mix and other leafy greens from Mexico until the Food and Drug
Administration (FDA, Silver Spring, MD, USA) had resolved the issue.
Foods 2013, 2 587
Secondly an announcement of possible contamination of the Clostridium botulinum was linked to a
concentrated-whey product distributed to food suppliers in a number of countries by Fonterra
(Auckland, New Zealand). This particular bacterium is known to cause botulism, a severe and deadly
form of food poisoning. Total financial loss is not yet clear. Initial news reports estimated that the
company lost more than $60 million within hours of the announcement of the potential contamination
in its products. It has been confirmed that 38 tonnes of whey protein products were contaminated.
There was a short-term trade disruption, but it is difficult to predict the longer-term impact. Countries
such as China, Russia and Sri Lanka imposed a temporary ban on some dairy products from
New Zealand. Government agencies are investigating the reasons for this incident. Fonterra also wisely
commissioned an independent inquiry into this incident which is now published and available on the
Fonterra website [4]. In the authors view this is an impressive report that is likely to become an
essential reference on handling such possible outbreaks [4]. More recently Danone (Paris, France), one
of the customers who received food safety alert, is seeking around €200 million ($270 million) in
compensation from Fonterra to cover the costs associated with the infant formula product recalls as a
result of the botulism scare [7].
The impact of this incident on small food companies based in New Zealand is much more severe;
either their business suffered badly or is likely to be forced to close down due to lack of sales [8].
Apart from this recent food scare in New Zealand, the overall economic cost of foodborne disease in
New Zealand was reviewed by Gadiel [9]. It is important that small producers understand the need to
have a risk assessment and a plan of how they will handle such an incident. In the authors view this
would most likely include independent experts.

Two other examples of expensive and devastating food safety incidents were noted in 2008 and
2009 [10]. A deadly outbreak of Salmonella food contamination was recorded in 2009 which
originated from a plant belonging to the Peanut Corporation of America (PCA, Lynchburg, VA, USA).
The outbreak resulted in over 700 cases of serious illness and at least nine deaths. Within days, a
second plant was also implicated in contamination, resulting in PCA permanently discontinuing
operations. In addition to the economic cost to PCA other food companies were affected. The food giant
Kellogg (Battle Creek, MI, USA), announced losses of $70 million related to recall-related losses and
Forward Foods of Minden, NV who make the Detour brand energy bars, was forced into bankruptcy.
Westland/Hallmark Meat Packing Company (Chino, CA, USA) issued the largest meat recall in the
U.S. history in 2008. At the request of the FDA, Westland/Hallmark recalled more than 143 million
Foods 2013, 2 588
pounds of beef. The cost of the recall to the company was over $117 million. In November 2012,
Westland/Hallmark agreed to settle $500 million on numerous affected customers and the federal
government. Before paying, the company was declared bankrupt. Recalls of this scale are rare but will
be increasingly frequent as global distribution supply chains improve, detection/sampling techniques
improve and regulated allowable limits for contamination fall.
Of late, food recalls have become very common. Using information from the U.S. and Canada,
there were more than 600 recalls during the past 12 months [11]. This massive number of recalls
indicates how often foods leave the manufacturer’s premises with a potential to cause serious health
risks to the consumer. Therefore food recalls are the method by which companies and government
regulators try to improve food safety by removing products from distributor inventories, store shelves
and consumers’ kitchens. The major reasons behind food products recall are recorded as
contamination, adulteration, misbranding and a compromised product. Contamination with a pathogen
such as Listeria monocytogenes, or presence of undeclared allergens such as peanut, can be quoted as
examples. Most of these recalls are precautionary and incur huge costs to companies’ operating
expenses. However, recall events are important for the manufacturer to maintain and regain consumer
confidence on suspicion of contamination in its products. Moreover, these are essential tools to allow
government agencies to remove potentially harmful products from the market rapidly and efficiently in
order to protect consumers and general public health.
3. Conclusions
The current situation highlights the need for food companies to increase the microbiological safety
of the foods that are produced for local or overseas markets to avoid unexpected food safety scares.
The economic implications of an outbreak are very serious and may cause the closure of an individual
company and long lasting damage to a particular sector of the food industry. Therefore it is important
for food companies to:
Understand global food safety issues.
Monitor changing conditions in business.
Consider the effect of transporting on foods.
Promote food safety by working with governmental agencies and professional associations.
Develop food safety awareness.

Historically, there has been a concern for the detection and enumeration of microorganisms in foods, and numerous methods have been developed to determine their microbiological conditions. The present study aimed to compare the numbers of microbes recovered with three sampling methods: drip, excision, and swabbing in vacuum-packed beef. The sampling methods were evaluated in terms of the viable numbers of Enterobacteriaceae, lactic acid bacteria (LAB), Brochrothrix thermosphacta, Salmonella spp., and yeasts and moulds (Y&M). The numbers of B. thermosphacta, Salmonella spp., Enterobacteriaceae, LAB, and M&Y recovered with the drip method were significantly higher (p < 0.05) than those from the other two methods. Regarding excision and swabbing, the recovery of B. thermosphacta and Enterobacteriaceae was higher (p < 0.05) with the excision method than swabbing, while there were no statistical differences (p > 0.05) between both methods for Salmonella spp., LAB, and Y&M. In conclusion, the drip method can recover up to two logarithms more than the other techniques in vacuum-packed meat; hence, it should be considered when designing and implementing sampling systems for the meat industry.
... Between 2014 and 2019, Cambodian Department of Drugs and Food report documented 134 foodborne disease outbreaks that resulted in 5,825 illnesses, with 96.1% rate of hospitalization and 1.4% rate of death (Thompson et al., 2021). Hospitalizations due to foodborne illness represent a significant healthcare and economic burden; hence, food safety plays an important role in public health, economic stability, global trade, and sustainable development (Hussain & Dawson, 2013). However, many low-and middle-income countries (LMICs), such as Cambodia, lack the resources required for largescale surveillance and have limited resources for the implementation of interventions for the management of microbial foodborne hazards and associated illness cases. ...
... Moreover, when food safety hazards exceed predetermined thresholds, they can result in financial burdens for the agrifood sector. These burdens include expenses related to regulatory compliance, contamination tracing, product recalls, plant shutdowns, cleanups, product liability, and enduring negative impacts on the market due to reputational harm (Hussain and Dawson 2013). The economic ramifications of foodborne illnesses can be assessed from many perspectives, such as the societal perspective or the consumer's perspective. ...
... Foodborne pathogens -especially from animal origin-pose a severe threat to global public health as well as the general economy and the society (Hussain and Dawson, 2013;Moi et al., 2022;Omer et al., 2018;Warmate and Onarinde, 2023). In this regard, slaughterhouses have been identified as significant reservoirs for a variety of bacterial pathogens, contributing to the emergence of zoonotic diseases and the spread of antimicrobial resistance (AMR) and virulence factors (Campos Calero et al., 2018;EFSA Panel on Biological Hazards (BIOHAZ) et al., 2021;Ferreira et al., 2013;Tu et al., 2024). ...

Slaughterhouse environments are prone to microbial contamination, influenced by factors like set-up, size and area as well as disinfection practices. Thus, effective control measures are crucial to prevent the spread of pathogens and their contaminant genes (antimicrobial resistance genes and virulence factors) throughout the food chain. In the present study, we assessed the microbial contamination in environmental surfaces of three slaughterhouses located in the Jaén province (Spain). We also evaluated the impact of different disinfection strategies on microbial loads and diversity by means of culture dependent and independent methods. The results revealed a statistically significant inter- and intra-specific differences in microbial loads including the most important pathogens such as pseudomonads, staphylococci, Escherichia coli, Salmonella sp. and Campylobacter jejuni. Disinfection strategies using routine disinfectant (used by the slaughterhouse), HLE disinfectant, UV, or combinations thereof showed varying effectiveness. The newly developed sustainable HLE disinfectant was most effective, while UV had the lowest disinfection strength, and routine disinfectants failed to eradicate all pathogens. Metagenomic analysis identified Pseudomonadota as the dominant phylum, followed by Actinomycetota and Bacteroidota. Results furthermore indicated shifts from sacrifice to cold rooms, with an increase in Gammaproteobacteria, particularly Moraxellaceae (represented by Psychrobacter cryohalolentis) over Acinetobacter sp. In conclusion, this study highlights the potential of HLE disinfectant (alone or in combination with the routine disinfectant) as a more effective disinfection measure on environmental surfaces, particularly for combating multi-drug resistant pathogens compared to other disinfection methods currently used.

A study was conducted to validate the plain bagel baking process as an effective kill-step in controlling Shiga toxin-producing Escherichia coli (STEC) in the event of pre-baking contamination originating from flour. Unbleached bread flour was inoculated with five strains of STEC and dried back to its original water activity levels. The inoculated flour was used to prepare the bagel dough, proofed, boiled for 2 min, and baked at 232.2 °C (450 °F) for 14 min mimicking the commercial manufacturing process. Additionally, water activity (aw) and pH in plain bagels during baking, and thermal inactivation kinetics (D- and z-values) of STEC in plain bagel dough were studied. The results clearly demonstrated that baking plain bagels at 232.2 °C (450 °F) for 14 min will result in at least a >5 log reduction in the STEC population, thus providing an effective kill-step assuring the safety of the finished food products. The pH of plain bagels increased significantly from pre-proofed plain bagel dough to seven min into the baking process, reaching a final value of 5.83. The water activity of the crust and crumb portions of plain bagels was significantly different during the baking process. The D-values of STEC in plain bagels at, 56, 59, and 62 °C were 26.3 ± 1.55, 9.0 ± 0.27, and 2.50 ± 0.15 min with a z-value of 5.8 ± 0.16 °C.
Chapter
The global food system faces numerous challenges, with food loss, waste, and safety emerging as key concerns. This chapter provides a comprehensive analysis of these critical issues, starting with an examination of global food loss and waste statistics. The main causes of food loss resulting from inefficiencies in production, handling, and distribution, are thoroughly explored. In contrast, food waste—which occurs at the retail and consumer levels due to improper storage, over-purchasing, and mismanagement—is also analyzed, highlighting the key differences between the two. Food spoilage is addressed as a major contributor to food waste, with a focus on its etiology and the factors that influence it. Various methods for detecting food spoilage are discussed, including microbiological identification techniques, biosensors, and chemical methods. Prevention strategies, particularly the application of hurdle technology, are also highlighted for their role in enhancing food preservation. The chapter concludes by addressing food safety as a global challenge. It offers a historical perspective on food safety and examines modern food control systems, such as the Hazard Analysis and Critical Control Points (HACCP) system. A holistic One Health approach, formerly known as One Medicine, to food safety strategies is proposed, addressing both chemical and microbial contaminants, as well as the growing issue of antimicrobial resistance, which threatens the safety and sustainability of the global food supply.

This study meticulously examined the nutritional composition and safety of seven commercial chicken burger brands available in the Sulaimani market. The investigation centred on various important aspects, such as proximate composition, physical properties, texture profiles and the identification of heavy metals. The moisture content, played a crucial role in determining texture and juiciness that differed among the samples. R7 had the highest moisture level at 64.2%, which was linked to improved sensory characteristics. The protein concentration varied between 13.20% and 18.60%. Furthermore, the fat content also showed significant variability, with R3 presenting the highest fat content at 20.80%, which enhanced the taste but also raised the caloric intake. The evaluation of ash content, representing total mineral content, combination with carbohydrate content, highlighted the crucial role of formulation for deciding the nutritional composition of these items. Physical analyses revealed substantial differences in weight loss and shrinkage among all samples, with R3 showing the highest weight loss at 26.2%, indicative of lower water-binding capacity. The texture profile analysis identified notable variation in hardness, chewiness, cohesiveness and springiness, while R4 demonstrating the highest hardness at 11,020 g, correlating with its higher protein content. This study provided critical insights into the nutritional quality and safety of chicken burgers, emphasizing the importance of meticulous ingredient selection and strict adherence to safety standards to safeguard consumer health. The findings contributed to a deeper understanding of how these products aligned with dietary guidelines and consumer expectations, underscoring the need for continuous monitoring and regulation within the rapidly evolving food market.

Foodborne diseases are a significant cause of morbidity (600 million cases) and mortality (420,000 deaths) worldwide every year and are mainly associated with pathogens. Besides the direct effects on human health, they have relevant concerns related to financial, logistics, and infrastructure for the food and medical industries. The standard pathogen identification techniques usually require a sample enrichment step, plating, isolation, and biochemical tests. This process involves specific facilities, a long-time analysis procedures, and skilled personnel. Conversely, biosensors are an emerging innovative approach to detecting pathogens in real time due to their portability, specificity, sensitivity, and low fabrication costs. These advantages can be achieved from the synergistic work between nanotechnology, materials science, and biotechnology for coupling biomolecules in nano-matrices to enhance biosensing performance. This review highlights recent advancements in electrochemical and optical biosensing techniques for detecting bacteria and viruses. Key properties, such as detection limits, are examined, as they depend on factors like the design of the biorecognition molecule, the type of transducer, the target's characteristics, and matrix interferences. Sensitivity levels reported range from 1 to 1 × 10⁸ CFU/mL, with detection times spanning 10 min to 8 h. Additionally, the review explores innovative approaches, including biosensors capable of distinguishing between live and dead bacteria, multimodal sensing, and the simultaneous detection of multiple foodborne pathogens — emerging trends in biosensor development.

This study investigates the potential impact of food safety outbreaks on domestic shipments, imports, and prices of the produce industry. Moreover, the compliance costs associated with new food safety standards were also estimated. Three case studies were analyzed to assess these potential impacts: the muskmelon (Cucumis melo) outbreak of Mar.-Apr. 2008, the spinach (Spinacea oleracea) outbreak of Sept. 2006, and the tomato (Solanum lycopersicum) outbreak of June- July 2008. The results demonstrate that the costs incurred by producers because of food safety outbreaks in produce are far greater than preventing such incidents.

Food safety has become an important food quality attribute within the last decade. In 2002, we conducted a consumer survey with 449 subjects in Kiel to determine actual consumer perceptions to food quality and safety. We compared these data with our former consumer surveys in Kiel. Over the past decade food quality is perceived to have improved. Regarding to food related health risks, the feeling of uncertainty appears to have decreased. With respect to the willingness to pay for food safety, two segments of consumers emerged, i.e. price-sensitive and safety-sensitive consumers. Food manufacturers have gained credibility from 1997 to 2002 although still on a low level. They should communicate actively their food safety initiatives as part of their ethical and social responsibility.
