In order to sustain life and promote good health, it is essential to have access to adequate quantities of safe and healthy foods. Globally, food contamination affects over 600 million individuals and kills almost 420,000 people annually. Food safety is a scientific approach that describes how to handle, prepare, and store food judiciously to reduce the risk of food-borne illness. Numerous contaminants pose a serious threat to food safety, and these include physical, chemical, and biological contaminants. Risk assessment deals with scientific analysis of known or probable adverse health consequences brought on by human exposure to food-borne risks, according to Codex Alimentarius. It offers a neutral scientific foundation for decision-making to guarantee the safety of the food supply. Methods of risk assessment and management to validate food safety can be improved by establishing standard protocols and policies for food traded nationally and internationally. This chapter highlights how risk assessment can be used to identify significant knowledge gaps. Characterization of the most significant risk factors in food production systems and implementation of risk reduction strategies to establish and secure human health are discussed. Additionally, various steps leading to food safety have been discussed in detail.

Pesticides still have a pivotal place in food production by protecting and increasing the yields of crops. Generally, farmers consider pesticides as essential tools to ensure plant protection and hence secure adequate income. Conversely, from the consumers’ perspective, they are one of the most worrying elements regarding food quality. In the EU, the legislation for authorization of pesticides safeguards an acceptable potential risk for consumers, farmers, and the environment when the products are used according to the label instructions. Furthermore, protection of food quality, human health, and environmental safety has been a major goal of the EU Common Agricultural Policy, as well as a driver for enforcing the European Green Deal in agriculture toward the reduction of pesticide use. Taking for granted that the EU legislative framework regarding consumer safety is strict and concrete, the emerging challenge is how to reduce non-dietary and environmental exposure (especially for non-target organisms) to pesticides through sustainable plant protection methods during cultivation and the safe use of pesticides for the farmer/operator, the consumer, and the environment. All these key elements are discussed thoroughly through the prism of the EU legislation.

Developments in the field of genetics have enabled the application of transgenic gene technology to food production systems in order to help meet the increasing world food demand since advanced technology enables increased food productivity and longer shelf life. First, towards the end of the 1990s, a genetically modified tomato product was obtained, and in the following years genetic modification studies were carried out on products such as corn, cotton, and rapeseed. Although these studies show various advantages for food production, there could also be several concerns in terms of public health. The transfer of genes isolated from a food containing allergen compounds to a food that has not caused allergy before, or is less likely to cause allergy, carries a risk in terms of cross-activity and development of a new allergenic food. Today, it is known that there are approximately 170 foods that have been found to contain food allergens. However, it is thought that transferring a gene isolated from a food that contains a food allergen to another food that does not contain allergens may cause much more allergenic food production over time. Therefore, this study aims to bring an updated approach to the risk of food allergens in genetically modified foods.

Milk is a highly nutritious and complete food that provides essential nutrients such as carbohydrates, fats, proteins, minerals, and vitamins required for normal metabolism and maintenance of life. However, in recent times there has been a growing concern over the safety of milk and dairy products due to their contamination by physical, chemical, and biological agents. Contamination of milk can occur from various sources, such as the environment, cattle, and personnel handling. Antibiotics and pesticides enter milk through animal feed and fodder contaminated with these substances. The increased demand for food has led to an increase in pesticide use in crops, which indirectly enters milk and dairy products. Additionally, feed and fodder contaminated with molds such as Aspergillus flavus and Aspergillus parasiticus produce aflatoxin that can make milk toxic. Heating or pasteurization cannot destroy aflatoxin since it is heat-stable. Milk is also easily contaminated with microorganisms like Escherichia coli, Listeria monocytogenes, Salmonella, and Bacillus cereus. Refrigeration after milking is crucial to inhibit the growth of these microorganisms. Milk can be contaminated because of animal ill health, unhygienic environments, milk conserving practices in herds, and improper storage temperatures. The presence of various pathogens and spoilage microorganisms in milk can cause foodborne diseases like gastroenteritis, tuberculosis, cholera, and even death by bacterial toxin. Therefore, it is important to raise awareness about milk and dairy product contamination and its impact on milk production, food spoilage, foodborne diseases, and human health.

Meat is a very rich and convenient source of nutrients compared to foods of plant origin. Due to its high nutritive value, meat can be contaminated by microorganisms when not handled judiciously, by chemicals and toxins like nitrite and heavy metals through bioaccumulation and biomagnification, and by veterinary drugs. Major contaminants can come through physical, biological, chemical, and cross-contamination such as through water, air, dust, microbes, equipment, insects, and employees. Consumption of contaminated meat products may lead to significant morbidity and mortality, especially through foodborne diseases that are hazardous to children, vulnerable people, pregnant women, and immunosuppressed individuals, and therefore has adverse socioeconomic and health implications. Monitoring and surveillance of meat products at all stages of production, processing, and distribution in the supply chain, for hazard identification and evaluation of potential pathogenic microbial diversity from farm to consumer, is a key component of ensuring food safety. This chapter describes the types, sources, and causes of food contaminants as well as the factors that have a significant impact on the safety of meat products. It also discusses potential measures to stop infection and contamination of meat throughout the production process, giving consumers the assurance that the quality and wholesomeness of meat products will be preserved to safeguard their health.

Poultry products form one of the main nutritious protein sources for the human diet. However, there are several issues concerning various kinds of contamination in poultry and egg products. In this chapter, we discuss several harmful chemical contaminants and their sources in poultry meat and eggs, along with risk analysis of their hazardous effects and detection in various matrices. Compared to backyard hen eggs, chicken farm eggs have greater concentrations of metals like Pb, Mn, Cr, Cu, and Se, which may be related to the consumption of contaminated feed. There are numerous ways that chlorinated insecticides and halogenated environmental pollutants might get into laying hens. Residues from veterinary drugs, environmental pollutants (dioxins, pesticides, phthalates, polycyclic aromatic hydrocarbons), natural contaminants (mycotoxins, microbial contaminants), and phytosanitary substances can accidentally contaminate poultry meat and eggs during the production or marketing stages. These items might include some chemical and natural components with harmful qualities at detectable or even very low quantities because of the growing industry demand that is leading to disease control and environmental issues. Globally, new concepts and solutions for chicken food security have been created to protect consumers from unwanted effects such as genotoxic, immunotoxic, carcinogenic, teratogenic, or endocrine disrupting effects.

Foodborne diseases in seafoods have become a prominent and widespread food safety issue. Severe food poisoning induced by digesting contaminated seafoods may lead to severe vomiting, diarrhea, dysentery, dehydration, and even death, and other poisoning symptoms occur from time to time. The most common causes of foodborne diseases of seafood are contamination with pathogenic bacteria, viruses, biotoxins, chemical pollutants, and other pathogenic factors. In this chapter, we will put forward an update on various types of seafood contamination and different federal regulations involved in monitoring these contaminations. Additionally, this chapter summarizes all kinds of food contaminants in seafoods and makes a classification of the food contaminants according to their properties and structures. The maximum residue limits (MRLs) for the contaminants will be listed and compared using different standards, as well as their possible sources. Additionally, we will discuss the current challenges and prospects of food contaminants in seafood, to provide innovative tactics for controlling such contaminants.

Food contaminants are harmful substances found in food that can harm humans when consumed. Usually, these contaminants are not added purposefully, but food may contain these substances as a result of the manufacturing, packaging, transport, or holding processes. They could also be brought on by environmental contamination, and some contaminants can develop organically, transfer from soil, water, or air to food, or they can be produced as a by-product of food production. Three general categories of food contaminants can be found in fruits and vegetables: biological, chemical, and physical contaminants. Furthermore, worldwide regulatory agencies have come forward to reduce such contaminants in foodstuffs because contamination usually degrades food quality and may indicate a risk to human health. The regulatory authorities check food products to ensure they adhere to the regulatory standards. For imported foodstuffs, the country of origin is responsible for the compliance, and due to their toxicity or possible presence in the food chain, contaminants that pose the greatest threat to consumers have a maximum permissible limit. These contaminants include nitrates, dioxins, heavy metals (like lead and mercury), and aflatoxins. In this chapter, we briefly discuss various fruit and vegetable contaminants, including those produced by farming, industry, chemical toxins, animals, microorganisms, humans’ activities, and those produced physically.

Non-alcoholic fermented cereal-based beverages (NFCBs) are traditional drinks consumed worldwide. The aim of this article is to analyze the contaminants present in NFCBs and propose methods to reduce them to ensure the safety and quality of these beverages. The study provides an overview of the NFCB production process, with a specific focus on NFCBs from Africa, Asia, Europe, and the United States. The analysis identifies a range of chemical contaminants, including mycotoxins, heavy metals, biogenic amines, and pesticides, as well as biological and physical contaminants that can compromise the safety and quality of NFCBs. The potential health risks associated with the consumption of contaminated NFCBs are discussed, underscoring the criticality of regulating the production process and ensuring that acceptable safety standards are met. The article also proposes various methods to reduce the contaminants found in NFCBs, including better agricultural practices, alternative control measures, and modern technologies to improve food safety.

Food additives are either natural, semi-synthetic, or synthetic compounds that are intentionally added to foods at levels ranging from 1 ppm to 10,000 ppm. Some additives are used directly in food items to enrich their organoleptic qualities, improve stability and shelf life, and enhance market demand. In contrast, others are employed in production and processing indirectly. Leavening agents, flavors, colors, preservatives, texturizing agents, antioxidants, and other ingredients are frequently employed as direct additives. The use of these chemicals has increased due to the revolution in food processing. If food additives are ingested in excess, a number of health issues could arise. Additionally, as synthetic chemicals gradually build up in the body and get embedded in cell structures, the body’s natural chemistry is disrupted. Organ failure might result from long-term consumption. We have covered a wide range of food additives in this chapter, along with their chemistry, functions in food processing and preservation, and potential health risks. Additionally, criteria for safe use, as well as acceptable daily intakes (ADI) of authorized additives and/or preservatives, have been presented.

Foodborne viruses are amongst the top priorities and concerns regarding food safety. Foodborne viruses can create significant outbreaks of diseases which can lead to heavy burdens on health. Viruses are obligate microorganisms that require susceptible hosts for propagation, and food serves as a medium for transport to a host. Foodborne virus are transmitted through the fecal–oral route by ingestion of contaminated food. Infected food handlers, infected animals, and feces are identified as major routes for transmission. The majority of foodborne virus are identified by PCR (polymerase chain reaction) methods. Quantification methods can be used to develop acceptance levels and assess risks. PCR methods need to be refined so as to better predict the infectivity of viruses. Cell culture methods can also be used to detect some enteric viruses. Various intrinsic and extrinsic properties can be modified and controlled so as to control and prevent the growth of viruses in food media. These include pH, water activity, relative humidity, temperature, and additives. However, in the case of viruses a combined effect demonstrates a substantial effect on the infectivity of a virus. An understanding of viral detection, control measures, and risk assessments is required for adequate food processing technologies and prevention of foodborne illnesses.

Microplastics (MPs) are solid microscopic fragments of plastic materials and are widely distributed in water, soil, air, and biota. MPs cause damage and accumulate in animals such as aquatic organisms, including edible fish, and reach human systems through the food chain (biomagnification). MPs have been found in human blood and lungs, and food exposure requires particular priority. The comprehension of mechanisms by which MPs enter the human body is still scarce. Thus, considering the indirect exposure of food to MPs and the potential to affect human health, this chapter will present current knowledge about the main MP characteristics, levels, and the ways they affect human health through food, especially seafood consumption.

The presence of 3- and 2-monochloropropane-1,2-diol esters (3- and 2-MCPDE) and glycidyl esters (GE) in lipid-food products has increasingly become a concern worldwide. These esters are hydrolyzed in the gastrointestinal tract and are potentially carcinogenic. These contaminants are formed during the refining process of crude palm oil whereby lipids such as triacylglycerols and diacylglycerols react with the chlorides at high temperatures. This severe deodorization promotes the formation of 3-MCPDE and GE. Analytical methods include the conversion of the individual fatty acid esters, followed by the derivatization of analytes before gas chromatography–mass spectrometry (GC–MS) following the American Oil Chemists’ Society (AOCS) Official Method Cd 29a-13. The aim of this chapter is to compile the surveillance data of 3- and 2-MCPD and glycidol in selected processed foods available in the literature. The data showed that the mean concentration of compounds in edible oils, infant formula, bakery products, cereals, fish and fish products, meat and meat products, margarine and spreads, snacks, soy sauces, and hydrolyzed vegetable protein (HVP) ranged from 0.006 to 10.00 mg/kg for 3- and 2-MCPD and 0.0023 to 18.00 mg/kg for glycidol. Health risk estimation revealed that residues of 3- and 2-MCPDE found in these foods exceeded the Tolerable Daily Intake (TDI) of 2 µg/kg body weight per day which suggests a great potential for chronic toxicity to consumers.
