Ordering a salad delivery or opting for packaged vegetables in fast-food type meals requires care when you consume them in search of a healthy diet. The idea of "ready for consumption" runs high risk of contamination. A study conducted in Campinas (SP) found bacteria in 90% of the saline samples badyzed.
Microbiological tests were carried out by UniMetrocamp Wyden University Center in fresh salads, 12 of which were from deliveries and the remaining eight from fast foods.
of them contained faecal coliforms in quantities ten times higher than those tolerated by the National Agency of Health Surveillance (Anvisa)
"Salads made from vegetables and raw vegetables, seasoned or not, in sauce or not, the limit is 100 (19659002) "Only two of the salads badyzed were fit for human consumption."
"What surprised us was the amount of coliforms that were present in the samples. Anvisa recommends about 10², 100 [coliformes por grama] We found ten times more. of those people who sell these products, "says the doctor of food science, biologist, professor and coordinator of the study, Rosana Siqueira
These foods are already subject to fertilization, fertilization and sometimes bad irrigation. […] Tomatoes, cucumbers, radishes, which are often eaten with the envelope, we must be careful to wash them. "
" This product already reaches the merchant in a large amount of microorganisms. "
Bacteria of Evil
Research is part of the conclusion of the undergraduate course in biomedicine students Milene Almeida, Tamires Teixeira and Jacqueline Camargo.
" In fast food we went to places, we took these samples and brought them here to inoculate [colocar o alimento num meio específico para testar se há crescimento de micro-organismos]. The same thing happened with the delivery we called and they brought us here, "says Milene
Escherichia coli, main indicator faecal contamination, was also found in 11 samples. According to the researchers, this bacterium is present in the human and animal intestinal microbiota.
Opportunistic to further harm the health of those who were already weakened, the bacterium Pseudomonas aeruginosa had amounts greater than 1.2 million
Another bacteria that attracted attention was Staphylococcus aureus, usually present in the nasal cavity. Ingesting can lead to food poisoning. Molds and yeasts were also present in the salted samples.
"For immunocompromised people, it can cause gastric diseases to pneumonia, Escherichia coli causes diarrhea, nausea, fever, Staphylococcus aureus […] can cause intoxication food, very common in the population ", warns Jacqueline.
You must wash again
The exit is to wash the salad again Yes, wash everything before consuming The coordinator teaches that the best substance for cleaning up vegetables and fruits is sanitary water, a product accessible to the people.
There is 10ml of bleach for 1 liter of drinking water, with 10 to 15 minutes of water. 39, immersion
"If you are in a place that does not have this possibility, season this salad.Use vinegar or a lemon.It will not give 100% safety,
Rosana reminds us that the board used for blow These foods should also be properly disinfected with bleach and then washed with running water. According to the researcher, the use of gloves, masks and haircuts is essential, according to the researcher.
Who can not disinfect the salad can use vinegar and lemon, which reduces contamination, such as seasoning. function (d, s, id) {
