How has food safety management been adjusted with Covid-19?
The food, beverage and hospitality industry are following stringent health and hygiene practices, with the traceability of products being carefully controlled and monitored in real time.
Are there more dangers eating raw food?
As a general rule, the consumption of raw or undercooked animal products should be avoided. Raw meat and milk products should always be handled with care to avoid cross contamination with uncooked foods.
Sushi for example can have bacteria and parasites like Anisakiasis, which can cause vomiting, diarrhea and stomach pain. It’s also wise to avoid fish that could be high in mercury, like swordfish and tuna.
Chefs have to be extremely vigilant in the preparation of raw and ready to eat foods. Wearing gloves to prevent cross contamination, maintaining excellent food hygiene and food safety practices can prevent virus transmission through food.
What role does temperature play?
Covid-19 is susceptible to a normal cooking temperature of 70 degrees. Studies have shown the virus can persist on different surfaces depending on a combination of parameters such as temperature, humidity and light. For example in a fridge at 4 degrees Covid can remain viable for up to 72 hours. The virus appears to be stable at low and freezing temperatures.
The idea behind heating food is that it destroys its nutrients and natural enzymes. Enzymes boost digestion and help fight chronic disease. Some fans of a raw food diet believe that cooking makes food toxic, whilst others claim a raw food diet can clear up allergies and boost immunity and memory.
Due to the risk of food poisoning, a raw food diet isn’t recommended for pregnant woman, young children, seniors and people with compromised immune systems, as well as those with chronic medical conditions.
People that choose to eat a raw food diet generally exclude animal products, therefore vitamin supplements are necessary to fill in the gaps in their diet.
What kind of foods should people be eating to boost their immune system?
Nutrition and other lifestyle measures influence immune strength and susceptibility to infectious diseases. What we do know is that diet, vitamins, minerals, antioxidants and sleep play a vital role in keeping our immunity strong.

What are some areas that are now being viewed differently in the industry?
Chefs have now become aware of the dramatic impact on the environment due to wastage and toxic chemicals being used worldwide. The food and beverage industry also has to take responsibility in this new normal by using environmentally friendly disinfectants, which is a must for my clients in health, wellness and spa businesses.’
It’s essential to maintain a safe, professional environment with a sustainable mindset towards chemicals in order to be in harmony with healthy living and treating food and cooking as our medicine.
Sustainability is not negotiable post Covid-19.
