Introduction

Fieldbrook Foods Corporation of Dunkirk, New York, issued a voluntary recall of 20 cases of the Tops brand of Orange Cream Bars and 320 cases of the Meijer Purple Cow brand Orange Cream Bars due to the possibility that the product may be contaminated with Listeria monocytogenes. Consumption of food contaminated with Listeria monocytogenes can cause listeriosis, with high fever, severe headache, neck stiffness, and nausea as its primary symptoms. In rare cases, listeriosis is fatal; it can also cause miscarriages and stillbirths. Pregnant women, the very young, elderly, and persons with compromised immune systems are the most susceptible.

Listeria monocytogenes is a gram-positive pathogenic bacteria that causes listeriosis in which infections primarily occur in the central nervous system, causing meningitis and other brain disorders, especially in newborn babies and pregnant women. The use of biomaterial as antimicrobial agents is environment friendly and low health risk strategy. Essential oils such as cinnamaldehyde possess excellent antimicrobial activity. A biocomposite of starch and lipid, on the incorporation of emulsion of the antimicrobial cinnamaldehyde, shows high toxicity to L. monocytogenes. Hence, this composite can be used to treat listeriosis [93]. During pathogenic infection, controlled release of the antibiotic drug is preferred to combat the infection. Antibiotic-loaded nanoparticles are gaining interest in this aspect. SLNs were prepared from a microemulsion of stearic acid, lecithin, sodium taurocholate, water, and ciprofloxacin. Such a nanoparticle- based system prolongs the release of the ciprofloxacin to combat eye and skin infections. For eye infections, this formulation is particularly advantageous because normally in other formulations, there occurs prompt release of the drug causing a very high initial drug concentration followed by sudden decline in concentration. To combat this, frequent administration of the drug is needed, which can cause toxicity. Also due to fluid and blinking reflexes of the eye, there is low drug absorption. Solid lipid nanoparticle- based formulations offer solution to both these problems by their enhanced penetration and gradual drug release and can also combat lung infections [94]. Solid lipid microparticles were embedded in the drug-loaded spongy matrix of chitosan and alginate to generate a composite that possesses the ability of controlled release of the drug, lidocaine HCl. Such composites are effective in wound healing as they counter microbes at the injury site [95].
The influence of society on the UK's food and food regulatory systems

Listeria monocytogenes – eating food contaminated with Listeria monocytogenes bacteria causes listeriosis – a serious infection that primarily affects individuals who are at a high risk for food poisoning: older adults, pregnant women, young children and people with weakened immune systems. Listeria can grow at refrigerator temperatures where most other bacteria cannot grow.

Listeria monocytogenes is a gram-positive, facultative anaerobic bacterium, capable of invading animal and human cells. This bacterial species causes listeriosis, which is a serious infection associated with encephalitis, abortions, meningitis and septicemia, being food an important serving source, both animal and fresh vegetables origins (Nalério et al. 2009). Listeriosis has a lower incidence when compared to other enteric diseases, but it is capable of generating more severe conditions and requires treatment with antibiotic therapy (Silva et al. 2016). This disease is associated with a high number of hospitalizations and has a lethality rate between 20 and 30%. Between 2013 and 2017, in the European Union, a significant increase in cases of this disease was observed (Dygico et al. 2019).

Bacterial human pathogens transmitted through fresh produce continue to be a worldwide burden of disease in almost every country in the world. Contamination may occur at each step of the production line, including fieldwork, packinghouse, and also during final processing once in the kitchen (Lynch et al. 2009). Foodborne bacterial pathogens such as Salmonella serotypes, E. coli pathotypes, Shigella spp., and Listeria monocytogenes may cause infections that run from mild self-limiting cases of diarrhea to severe symptoms, including sequelaes such as kidney failure and other life-threating conditions or death. Antibiotic treatments and chemical disinfection are the most assisted methods to stop events of pathogens contamination in foods. Both methods have made a significant advantage against pathogens spread thru contaminated water, soil, surface contacts and fresh produce. However, the increase application of antibiotics and chemical disinfectants has led to the emergence and spread of both antibiotic-resistant and disinfection-resistant bacteria. The development of alternative strategies to effectively reduce the contamination of fresh produce by bacterial pathogens is therefore a high priority (Behrsing et al. 2003; Bhardwaj et al. 2015).
