The ongoing technological development has caused some obvious lifestyle changes, including people opting for ready-to-eat (RTE) foods to save time. RTE foods are a group of convenient, readily available, nutritious meals that require minimal or no cooking or preparation time. As they are often consumed at the point of sale or later without any further processing, incidents of foodborne illnesses or pathogenic contamination have become quite common. The health risks associated with these products are quite disastrous and may lead to public health nuisances worldwide. The most common cause of such contamination is the mishandling of food, which may harvest pathogens or allow their entry through cross-contamination. Food handlers may be infected themselves and contaminate food or infect food through contaminated hands. Other causes may be inappropriate temperature exposure, contaminated utensils, and instruments, or defective packaging systems, which provide several pathways for invasion by microorganisms. Common pathogens may include bacteria, protozoa, algae, or even viral contamination that not only spoils the food completely but also compromises the health of consumers. Therefore, it is becoming a necessity to implement proper sanitary conditions and sufficient hygienic practices while handling RTE food. Administering normal food safety guidelines is repeatedly found to be insufficient, causing periodic outbreaks. Proper risk-assessment-based techniques must be implemented in the processing chain of RTE foods to reduce or control these shortcomings. This chapter focuses on a detailed discussion of pathogenic microbial contamination, hygienic measures, and other issues in RTE food.

Busy lifestyles, increasing individuality, an aging population as well as economic growth are the drivers of convenience. Convenience foods save time and energy. One of the concepts in the convenience food sector is ready-to-eat (RTE). RTE means that the food is pre-prepared and can be eaten right from the packaging without heating it. Consumers are on the hunt for healthy meals that have been prepared in advance. Packaging plays an important role here. Packaging is an essential component of the food system and plays a critical role in containing, protecting, and preserving food from the field to the end user. It needs to enable eating on-the-go because this is often where RTE products are consumed. Convenience food is a concept that has been prevalent in the developed world for a long time, while its inception into the Indian market has been recent. With the changing socio-economic pattern of life and the increasing number of working couples, the concept is fast becoming popular in the Indian market. This type of food is becoming popular because it saves time and labor. This food has an extended shelf life and is available off the market shelves. The food industry has seen great advances in the packaging sector since its inception in the 18th century with most active and intelligent innovations occurring during the past century. These advances have led to improved food quality and safety. While some innovations have stemmed from unexpected sources, most of them have been driven by changing consumer preferences. The new advances have mostly focused on delaying oxidation and controlling moisture migration, microbial growth, respiration rates, and volatile flavors and aromas. Sustainability initiatives led by global legislation, retailers, and corporations guide package material choices, design, and food packaging sales for food packaging professionals. Labeling is a means of performing the communication function of packaging, informing the consumer about nutritional content, net weight, product use, and so on. Labeling acts as a silent salesman through distinctive branding, as well as facilitating identification at check-outs through the Universal Product Code (UPC). Radio frequency identification (RFID) is a system that uses radio waves to track items wirelessly. RFID makes use of tags or transponders (data carriers), readers (receivers), and computer systems (software, hardware, networking, and database). The tags consist of an integrated circuit, a tag antenna, and a battery if the tag is passive (most active tags do not require battery power). RFID has recently found its way into numerous applications in the food industry, ranging from food monitoring and traceability to enhancing food safety, to improving supply chain efficiency. The major benefits of RFID technology in the food industry are greater speed and efficiency in stock rotation and better tracking of products throughout the chain, resulting in improved on-shelf availability at the retail level and enhanced forecasting. The technology is well-suited for many operations in food manufacturing and supply chain management.
