HIDDEN HYGIENE ISSUES IN FOOD SERVICE

And what you need to do to keep the kitchen clean

There's no question about it: if you go to a restaurant or café, you expect it to be clean. That is just part of creating a pleasant atmosphere. Even with a perfectly set table and a menu curated to be delicious, just a mark on the table or a plate that is not quite clean can ruin a diner's mood. They are sure to wonder what the kitchen is like, if that is the state of the table or plate.

Every restaurateur worth their salt will therefore pay close attention to keeping everything clean and hygienic – the table, the bar and the food preparation areas in the kitchen. That effort is not just for the benefit of the customer; it is a legal requirement.

Whether your run a café, high-class restaurant or the little bistro at the end of the road, all kids of potential hygiene problems lurk in the kitchen. Very often, they are not obvious at first glance or perhaps completely invisible to the naked eye. And they hide where you don't suspect. Do you think that your professionally equipped kitchen is hygienically clean? Let's take a closer look...

 

HACCP hygiene standards

Hygiene is everything in food preparation. Working in food production or preparation means complying with a long list of regulations. In many countries, companies are only allowed to process or sell food if they comply with HACCP guidelines. HACCP is a quality standard for the entire food industry – from producers to hotel kitchens. Further information is available here.

 

1. KITCHEN UTENSILS ARE BREEDING GROUNDS FOR GERMS

For example, dirty washing-up sponges and dishcloths make excellent breeding grounds for germs. No wonder, really. These are the precise tools that come into contact with stubborn dirt when we try to clean it, even in professional kitchens. More than 360 different types of bacteria could be contained in a kitchen sponge according to researchers in Germany who examined used washing-up sponges in 2017. This is a hygiene problem since some of these germs can cause illness. ‘Five of the ten most commonly found species are risk group 2 which means that they are potential pathogens,’ says study leader Markus Egert at Furtwangen University. And did you know that with the osmosis module in a MEIKO dishwasher, you will no longer need tea towels? Glassware, crockery and cutlery are guaranteed to be clean and shiny after the wash cycle – with no need to polish! ’

 

REGULAR WASHING HAS LIMITED BENEFITS

These bacteria can be a significant health risk, especially for people with weakened immune systems, such as the elderly or people with health conditions. They are invisible to the naked eye but they get everywhere: across worktops and knives, and ultimately finding their way into the food. The researchers found that carefully wringing out and drying sponges or even putting them through the washing machine will only help with hygiene to a certain extent. These measures kill or remove many bacteria in the short term but later on, even higher concentrations of pathogenic bacteria were detected in sponges that were cleaned regularly, that is compared to harmless bacteria. It seems that the harmful pathogens are able to kick start again, multiplying faster and using the ‘vacant’ space in the sponge to spread. The scientists conclude that kitchen sponges should therefore be replaced at least once a week or even more frequently.

2. SINKS AND WORK SURFACES

Microorganisms are persistent creatures. A sink can be freshly cleaned with a (preferably germ-free) dishcloth or washing-up sponge, the metal shining and sparkling back at you and yet it is still home to a veritable plethora of microorganisms. "By and large, these organisms occur throughout this environment. Many are waterborne microorganisms and moulds that are carried into the kitchen in foodstuffs," explains Professor Dirk Bockmühl of the Hygiene and Microbiology research group at Rhine Waal University of Applied Sciences in the magazine, "bento". He believes that a professional dishwashing machine is the way to get crockery properly clean, "Dirty items go into the dishwashing machine and come out hygienically clean."

STEAM AND MOULD

A busy kitchen creates mess – you've seen it at home. Commercial kitchens are no exception: worktops and appliances get dirty and need cleaning and tidying. Slaving over a hot stove produces an inordinate amount of dirty dishes. The kitchen team needs to get it all clean again in double-quick time. To do that, they need a reliable commercial dishwashing machine, preferably one that can handle constant operation. The dishwashing technology specialists at MEIKO provide efficient commercial dishwashing machines that save time with their short wash cycles and churn out hygienically clean and beautifully dry dishes by washing at a high temperature. Oh, and you won't need to polish anything, either.

On top of all that, MEIKO dishwashing machines release barely any visible steam after a wash cycle, avoiding heating the room unnecessarily. That is not to be sniffed at in the often hot and humid environment of a commercial kitchen. This has several advantages: the indoor climate in the kitchen and the efficiency of the kitchen staff are improved, not to mention it gives pesky mould no opportunity to form.
