Watermelons and melons sold already cut, common in supermarkets and fruit shops, may represent an increased risk of food contamination if they are not kept in constant refrigeration and handled hygienically, according to an alert published in Spain and replicated on social media.
The call to attention was shared by nutritionist-nutritionist Duna Nicolau in a video on TikTok and published by the Spanish portal 20minutos, in a context of purchasing habits that favor convenience.
At issue is what happens after the fruit is opened: the peel stops protecting the pulp and the food becomes more vulnerable to exposure and contact with microorganisms.
Why Cut Fruit May Be More Sensitive
When watermelon or melon is cut, the pulp is exposed to air, surfaces and handling, increasing the likelihood of contamination if hygiene and conservation conditions are not ideal.
In the alert, the specialist cites bacteria associated with foodborne diseases, such as Escherichia coli, Listeria and Salmonella, remembering that contamination can originate in several stages, including cultivation, transport and handling.
The risk can worsen if the already cut fruit is left out of the cold, even for short periods, because the combination of moisture and sugar favors the multiplication of microorganisms.
The “cold chain” is the critical point
The central recommendation is simple: after cutting, the fruit must remain refrigerated, without breaks in the so-called “cold chain”, from preparation to purchase and consumption.
If cut watermelon or cantaloupe is on display without adequate refrigeration, or if it spends too much time at room temperature, food safety may be compromised.
In addition to temperature, the issue of handling also arises: who cuts it, how it cuts it, with what utensils and under what conditions, factors that are difficult to confirm for the consumer at the point of sale.
What to do to reduce your risk at home
The safest option, according to the warning, is to buy the whole fruit and cut it at home, ensuring hygiene of your hands, cutting board and knife, and immediately storing the part that is not consumed in the refrigerator.
Before cutting, it’s a good practice to wash the outside of the skin (yes, even if you don’t eat it), to prevent the knife from dragging dirt into the pulp.
Once opened, the fruit must be well packaged (ideally in a closed container) and consumed within a few days, always respecting the smell, appearance and texture — any abnormal changes are a reason to discard.
Social networks, useful tips and caution
The case shows how platforms like TikTok have accelerated the circulation of health and nutrition advice, bringing everyday topics to public debate.
At the same time, and according to , the practical message remains: convenience should not replace basic hygiene and conservation care, especially with very perishable foods.
In the end, the question left by the expert sums up the essentials: it is worth saving a few minutes if it means less control over how the fruit was handled and preserved.
