“…Furthermore, sharing food such as popcorn from a common bowl can transmit disease-inducing bacteria, such as Escherichia coli (Baker et al, 2015). Thus, shared meals may elicit disease concern, reducing perceptions of positive interdependence that might otherwise emerge from commensal behaviours.…”

“…At larger scales, ritualized festivals that involve food consumption can promote bonding, but they can also lead to disease transmission because people eat from the same sources during these events (Centers for Disease Control and Prevention, 2014; Kitamoto et al., 2009; Lee et al., 1991; Ratcliffe et al, 2019). Furthermore, sharing food such as popcorn from a common bowl can transmit disease‐inducing bacteria, such as Escherichia coli (Baker et al., 2015).

Food sharing is central to the human experience, serving biological and sociocultural functions. Historically, food sharing has allowed people to manage food shortages, creating positive interdependence among those who pool calories and other sources of risk. However, sharing food may lead to negative outcomes when food is scarce, or when there is a threat of disease. We found that sharing food (compared with sharing pencils) led to reduced cooperation with an experiment partner (Study 1) and that perceived scarcity partially mediated a negative association between zero‐sum orientation and perceived interdependence with people involved in a recently shared meal (Studies 2–3). Disgust was also associated with lower perceived interdependence toward people involved in a shared meal (Study 3; NTotal = 1126). Our results suggest that scarcity and disgust can interfere with the positive feelings people might otherwise experience when eating together, warning against lay beliefs that ‘breaking bread’ necessarily brings people together.

“…The spread of respiratory diseases including coronaviruses (including SARS, MERS, COVID-19, H1N1 and avian influenza), pneumonia, Legionnaires disease, tuberculosis and the common cold have been attributed to oral airborne transmission. 35,36 Influenza virus particles were detected in the exhaled breath of infected individuals through coughing, breathing and talking. 24,25,26,37 When respiratory droplets are released, they spread infection directly from person-to-person or by contamination of surfaces then touched by others.…”

A major focus of food safety is on the contamination by microorganisms which occur during multiple stages along the food production and supply chain process. The microorganisms associated with foodborne illness are well-studied but normally do not include human nosocomial pathogens, particularly human respiratory diseases transmitted via mucosal droplets. A generally accepted mode of transmission for respiratory diseases include touching contaminated fomites followed by self-inoculation with fingers and hands by touching the face. Based on the existing modes of disease transfer, there is also the potential to spread these respiratory diseases through food. Several possible examples of direct transfer include sharing foods such as drinks, dipping sauces and popcorn while foods could also be indirectly contaminated by hands and utensils. Thus person to person transfer of disease agents seems likely by direct or indirect contact with food just prior to or during consumption.

Biology of Hand-to-Hand Bacterial Transmission

Numerous studies have demonstrated that adequate hand hygiene among hospital staff is the best measure to prevent hand-to-hand bacterial transmission. The skin microbiome is conditioned by the individual physiological characteristics and anatomical microenvironments. Furthermore, it is important to separate the autochthonous resident microbiota from the transitory microbiota that we can acquire after interactions with contaminated surfaces. Two players participate in the hand-to-hand bacterial transmission process: the bacteria and the person. The particularities of the bacteria have been extensively studied, identifying some genera or species with higher transmission efficiency, particularly those linked to nosocomial infections and outbreaks. However, the human factor remains unstudied, and intrapersonal particularities in bacterial transmission have not been yet explored. Herein we summarize the current knowledge on hand-to-hand bacterial transmission, as well as unpublished results regarding interindividual and interindividual transmission efficiency differences. We designed a simple in vivo test based on four sequential steps of finger-to-finger contact in the same person artificially inoculated with a precise bacterial inoculum. Individuals can be grouped into one of three observed transmission categories: high, medium, and poor finger-to-finger transmitters. Categorization is relevant to predicting the ultimate success of a human transmission chain, particularly for the poor transmitters, who have the ability to cut the transmission chain. Our model allowed us to analyze transmission rate differences among five bacterial species and clones that cause nosocomial infections, from which we detected that Gram-positive microorganisms were more successfully transmitted than Gram-negative.
