On 7 June 2020, the United Nations celebrates World Food Safety Day, year 2020 would be the second year of celebration. This is driven by two of its particular offices, the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO).

What is Food safety?

The term Food safety depicts all practices that are utilized to guard our food. Food safety depends on the joint endeavors of everybody associated with our food supply. All along the food chain - from farmers, producers to retailers and caterers, legislation and controls are in place to reduce the risk of contamination, and also personally, each one of us has a role to play.

How does food become unsafe for consumption?

Food can get contaminated at any phase of production, processing, distribution, storage or preparation. For instance, germs can spread to food from unclean surfaces, utensils or hardware utilized in the case of during food preparation or at home in our own kitchen. Whenever chilled raw foods like meat or dairy items are left at room temperature for a really long time, for instance during thawing or transport to or fro the general store, microorganisms can grow faster than expected and pose a safety risk.

It's assessed that in the UK around a million people experience food borne disease each year. Food can become dangerous when it is contaminated with disease causing microorganisms, infections, parasites or synthetics. Side effects can range from mild to severe, but commonly include nausea, vomiting, diarrhea, stomach cramps, weakness, fever and chills. In severe cases, food borne illness can lead to hospitalization or even death.

A generous extent of the foodborne malady is inferable from inappropriate food preparation practices in consumers' homes. International concern about consumer food safety has prompted considerable research to evaluate domestic food-handling practices. The majority of consumer food safety studies in the last decade have been conducted in the United Kingdom and Northern Ireland (48%) and in the United States (42%).

Also, Cafés, cafeterias, and bars are the most as often as possible referred to foods implicated in reported foodborne disease outbreaks are consumed.  In any case, it has been accounted for that foodborne disease arising from foods consumed in private homes is three times more frequent than that arising from foods consumed in cafeterias. Focus groups and observational studies have also been used. One consumer food safety study examined the relationship between pathogenic microbial contamination from raw chicken and observed food-handling behaviors, and the results of this study indicated extensive Campylobacter cross-contamination during food preparation sessions. Observation studies recommend that generous quantities of consumers frequently implement unsafe food-handling practices. Knowledge, attitudes, intentions, and self-reported practices did not correspond to observed behaviors, suggesting that observational studies provide a more realistic indication of the food hygiene actions actually used in domestic food preparation. An improvement in consumer food-handling behavior is likely to reduce the risk and incidence of foodborne disease.

Added to this, ongoing food patterns have centered on the apparent prevalence and fortification of natural or 'unprocessed' foods. While fresh foods without a doubt have a significant role to play in a healthy diet, these patterns may prompt a propensity to think little of the advantages that handling strategies like canning, purification, or freezing can give regarding wellbeing and time span of usability. For instance, tinned vegetables remain safe to eat for quite a long time, and are a helpful and reasonable approach to add vegetables to your eating routine.

Patterns like these are of specific concern when they lead to hazardous food decisions, for instance on account of raw milk items. Raw milk is getting increasingly well known in spite of the way that it has been connected to episodes of Salmonella, Campylobacter, and Listeria, and caused instances of extreme ailment. Then again, the procedure of purification (warming for brief timeframes to eliminate microorganisms), is straightforward, modest and viable at disposing of these organisms, while having little impact on the dietary benefit of milk.

'Food safety: everybody's business!'

Food safety is a common duty, and everybody has a task to carry out including governments, industry, makers, business administrators, and buyers. This is reflected in the subject of the day 'Food safety: everybody's business!'

FAO and WHO are supporting their Members in endeavors to give enough safe food to all and to empower individuals to believe that what they eat is safe. Events like World Food Safety Day help by featuring the critical role played by all those who work to ensure that they are not derailed by disruptions and other challenges to continue keeping foods safe.

Food safety during COVID 19.

The current worldwide emergency brought about by the COVID-19 pandemic has underscored like never before the significance of checking and tending to food safety. It has likewise featured the requirement for food safety frameworks to be adjusted to react to interruptions in supply chains and ensure continued access to safe food.

 World Food Day 2020 is devoted to each one of the individuals who have guaranteed that the emergency has not intruded on supply chains and that safe food stays accessible, contributing to the consumption of safe and healthy diets.

How to manage food safety?

The hazards related to contamination, decontamination, or survival of biological hazards during processing are well-defined and can be controlled by applying Good Manufacturing Practice (GMP), Good Hygiene Practice (GHP), and an all-around structured HACCP-program. Likewise, the means to prevent the growth of pathogenic microorganisms during distribution and storage of the final products are – with a few exceptions – available. Proper application of well-known preservative parameters including temperature is able to control the growth of most pathogens. 

Food packaging assumes a significant job as a physical hindrance to shield food from harm, defilement, and altering during transport and storage. Numerous foods additionally need security from dampness, air, or light to protect them & keep them fresh and safe to eat for longer, and even basic packaging materials like glass, plastics and paper can do a ton to improve wellbeing and broaden time span of usability.

Need for food hazards assessment.

With respect to chemical hazards in food, a risk assessment approach provides the opportunity to broaden the understanding of acceptable daily intakes, maximum residue levels, and their public health significance. Guidelines for chemicals in foods will inevitably have to address the differences between safety evaluation and a genuine risk assessment approach.

Food can be considered as an extremely complex and variable chemical mixture. Hazard characterization of low molecular weight chemicals in food and diet generally uses a no-observed-adverse-effect level (NOAEL) dose as the starting point. For hazards that are considered not to have thresholds for their mode of action, low-dose extrapolation and other modeling approaches may be applied. The default position is that rodents are good models for humans. But, some chemicals cause species-specific toxicity syndromes. Information on quantitative species differences is used to modify the default uncertainty factors applied to extrapolate from experimental animals to humans. 

Hazard characterization of micronutrients must consider that adverse effects may arise from intakes that are too low (deficiency) as well as too high (toxicity). Interactions between different nutrients may complicate such hazard characterizations. The principle of substantial equivalence can be applied to guide the hazard identification and hazard characterization of macronutrients and whole foods. Macronutrients and whole foods must be evaluated on a case-by-case basis and cannot follow a routine assessment protocol.

As for microbiological hazards, the unique problems associated with risk assessment of living organisms in food make it likely that the application of guidelines in the medium term will more commonly use qualitative approaches. Without a background marked by security assessment as indicated by a notionally zero hazard benchmark, similar to the case with synthetic substances, the goal of microbiological risk analysis to diminish microbial hazards to " the minimum which is technologically feasible and practical" speaks to a veritable concentration for chance evaluation. As risk assessment is increasingly applied and internationally accepted guidelines become established, decision criteria for risk management arguably present the greatest challenge in establishing and maintaining quantitative SPS measures for food in international trade and judging their equivalence. However, the desire of all interested parties for scientifically justified food safety measures may be tempered according to the ability of the global scientific community to generate the necessary data and the political will to accept food safety programs in different countries that have equivalent outputs.
