In the daily race, fast food and delivery become the first choice for food. But you have to be careful even when choosing a salad in one of these conditions. Research conducted at the UniMetrocampo Wyden University Center in Campinas, São Paulo, reveals that 90% of the badyzed ready-to-use salads were contaminated. Of the 20 samples evaluated, 18 contained 10 times more faecal coliforms than those authorized by the National Health Surveillance Agency (Anvisa) – up to 100 Colony Forming Units (CFU) per gram or milliliter [19659002] The survey was conducted for two months by students of the institution's biomedicine course, guided by biologist Rosana Siqueira, a professor at the institution. They badyzed 12 delivery salads and eight fast food salads. The bacterium Escherichia coli Staphylococcus aureus and Pseudomonas aeruginosa in addition to molds and yeasts (which are fungi) organisms that cause poisoning and l 39; ;infection.
"We have chosen the fastest foods that are the most frequently badyzed, we do not like naming the names because of ethics, but they are the ones that attract the most attention and attention. attracting a large number of people.With regard to delivery services, we select those who deliver leaflets in the streets.This branch starts now, the delivery of the salad.The choice of Campinas was due to the fact that we live here and that we had access to it, "says Rosana.
The theme became a course completion work (CBT)." The students chose (the salad) because it's considered a very healthy food, which contains fiber. Today, we talk a lot about eating well, but sometimes people do not know what they eat, "says the teacher.In the course of the research, the badyzes were done the same day , to avoid the growth of microorganisms from one day to the next.
Rosana recalls that of the 20 samples badyzed, only two did not have microorganism growth – both from the delivery.Of the 12 samples from fast food, ten were unfit for consumption.
The teacher says that the results have surprised and warned: "It is impossible to 39, be free of microorganisms. We must be aware that we can eat such a product. We were scared because we did not believe that we would find large amounts of microorganisms in salads. "
The results, according to the teacher, can not be applied to the country in general.However, it says that they serve as a warning to consumers." It depends on how the product is transformed from production to the final consumer. (The whole process) can be good at one place and bad at another, and the population can receive a different product, according to the manipulator, "he says [196459002] ] Care. Biologist Rosana Siqueira says that the consumer should wash the salads again or the fast food. If this is not possible, adding a little vinegar, lemon or salt can reduce the risk of contamination.
