How long does mayo last unrefrigerated?
The case of the 20-year-old Belgian who died after eating a pasta dish cooked five days earlier and left in the kitchen at room temperature may seem extreme. However, that leaves one question unanswered: how long can a pasta dish stay out of the fridge without endangering health if it is overheated and eaten later? As Dr. Fernando Luca de Tena, a specialist in the digestive system at the Medical-Surgical Center for Digestive Diseases, points out, “if we prepare a pasta or rice dish and let it cool to room temperature, on the table and without refrigerating, don’t let it pass more than 24 hours before consuming it so that its consumption is safe ”.
On this point, Daniel Giménez, member of the board of directors of the Spanish Society for Food Safety and Quality (SESAL) and a veterinarian specialized in food science, food technology and hygiene, points out that the duration of 24 hours is excessive. “If the surface temperature is additionally that of a domestic kitchen (20º to 28º C), the rice or pasta dish incorporates meat or white sauce and therefore the consumers of the dish are populations at risk (sick, pregnant …) the risk of food poisoning is very important ”, he emphasizes.
It should be noted that after two hours without refrigeration, bacterial growth occurs, so the ideal would be to cook food outside the refrigerator for a maximum of two hours. And in case the ambient temperature is high, at most one hour.
Is “Bacillus cereus” bacteria dangerous?
The case of the food poisoning of the young Belgian arose as a result of the growth of the bacterium “Bacillus cereus”, which, according to the SESAL expert, is not considered a “very dangerous” pathogenic bacterium but is one of the most complicated. It has two capacities: that of forming spores (forms of resistance that certain bacteria pass under unfavourable conditions) and that of producing toxins of two types, one of diarrhoea and the other of emetic (vomiting).
The problem with the bacterium “Bacillus cereus”, as revealed by Daniel Giménez, is its ability to manufacture toxins under favourable conditions. In this sense, the expert warns that, in addition, emetics are resistant to heat (90 minutes at 121 ° C).
Refrigeration is prevention
The expert assures that the habit of leaving food on the kitchen counter without putting it in the refrigerator is more frequent than it seems and although the incidence of poisoning by the bacterium “Bacillus cereus” is minimal, it is recommended to follow the official instructions storage and refrigeration of food.
The ideal way to prevent this growth of this bacterium is to store cooked food after cooling it in the refrigerator, at a temperature below 5 ° C. Or, for greater safety and if it has to be consumed a few days later, keep it. in the freezer.
According to the recommendations of the Spanish Agency for Consumption, Food Safety and Nutrition (AECOSAN), once cooked, the food should be placed in suitable containers and should not be left out of the fridge for more than 2 hours, or more than an hour. if the temperature is above 30 ° C.
In the case of salmonella, the recommendation is stricter because in less than 2 hours out of the refrigerator an omelette “with a small fixed egg”, or a homemade mayonnaise or even fish and meat, are often potentially dangerous to health.
How long does each food last in the fridge and freezer?
A quarter of food poisoning is due to inadequate refrigeration since pathogenic microorganisms reproduce rapidly if they are at room temperature, according to experts from the Organization of Consumers and Users (OCU), who insist on taking extreme precautions to avoid risks, especially in summer.
As a guide, the OCU experts indicate through these guidelines how long some of the most common foods last in the fridge and freezer: beef fillets (2-4 days in the refrigerator and 6 to 12 months in the freezer), chicken or turkey (1-2 days in the refrigerator and less than 12 months in the freezer), white fish (1 to 2 days in the fridge, 6 months in the freezer), oily fish (1 to 3 days in the fridge and less than three months in the freezer), pork chops (2-4 days in the fridge and 4 to 6 months in the freezer), minced meat (1-2 days in the refrigerator and 4 to 4 months in the freezer), UHT milk (3 to 4 days in the refrigerator and should not be frozen), open fresh milk (1-2 days in the refrigerator and less than three months in the freezer), eggs (less than three weeks in the refrigerator and cannot be frozen) and separate yolk or egg white (2 to 4 days in the refrigerator, less than 12 months in the freezer).
Regarding processed foods, OCU experts say that an open jar of mayonnaise (lasts less than a month in the fridge, cannot be frozen), bread (does not keep in the fridge and lasts from 3 to 6 months in the freezer), butter (3 to 4 weeks in the refrigerator and 6 to 8 months in the freezer), fresh sausages (1 to 2 days in the refrigerator, and 1 to 2 months in the freezer), cold cuts and cold cuts (3 to 6 days in the fridge, 1 to 3 months in the freezer), soups (2 to 4 days in the fridge, and 2 to 3 months in the freezer), ready meals (2 to 4 days in the fridge and 3 to 4 months in the freezer), sauces and meat broths (2 to 3 days in the fridge and 2 to 3 months in the freezer)
How are food scraps preserved?
The remains of cooked food should be put in the fridge as soon as they cool (or better, as soon as they stop burning), placing them in clean containers and without waiting for them to reach room temperature. Ideally, they shouldn’t stay out of the fridge for more than two hours, ”they explain. In the event that they are not going to be consumed immediately, it is advisable to freeze them, noting the date on which they have been placed in the freezer.
Another tip is that defrosting a food should never be done at room temperature but in the least cold area of the refrigerator. If a faster formula is desired, it will be made in the microwave or cooked directly.
No products found.
A fresh product that has already been thawed for cooking can be re-frozen again but only if it has been cooked before, according to the OCU. In this sense, they recommend that the food be heated well until it reaches, at least, a temperature of 80-90ºc so that the bacteria that may have grown are destroyed.
Food or products that have been opened must be wrapped, covered with plastic or must be closed with specific tweezers. In addition, OCU experts recommend marking them with a label indicating the date of opening. In the event that a can has been opened and remains remain, it is advisable to change the contents to a glass container.
