Be it your salad on a Sunday brunch, a delicious burger/sandwich, slices of tangy raw tomatoes are an indispensable part of our everyday diet. Unfortunately, there is a piece of disheartening news. A team of microbiology researchers at the Indian Institute of Science (IISc), Bengaluru, have discovered that raw tomatoes pose a risk of serious stomach infection, even after thorough washing with water, reported The Hindu.

Samples of raw tomatoes were found to contain Salmonella typhimurium, the bacteria that is responsible for gastroenteritis. However, the bacteria are killed by cooking. A press release from IISc on January 9 stated that unlike the popular notion, Salmonella contamination does not occur post the harvest during transportation and handling. Rather, the bacteria have a unique mechanism to enter the growing plants in soil contaminated with faecal waste matters. The paper for this discovery has been published in BMC Plant Biology.

Salmonella enter through lateral root openings

When the primary root of a plant develops minute openings for the development of lateral roots, Salmonella bacteria can penetrate inside through the pores. The bacteria lack the requisite enzymes to dissolve cellulose and pectin in the plant cell wall; hence they depend on the natural entry points to infect the plant.

“This is the first time we have shown how different it is from other plant pathogens based on its ability to colonise the roots,” shared PhD scholar Kapudeep Karmakar, one of the researchers in the team, with The New Indian Express.

The study has revealed that lateral roots in tomato plants have a much higher colonisation of Salmonella bacteria than any other parts of the plant. The researchers artificially induced more lateral root formation in an Arabidopsis plant (used as an experimental model) and found that the bacterial concentration multiplied with the increase in the number of lateral roots. In addition, increased salinity of the soil is another factor that promotes Salmonella infestation in the roots of tomato plants, from where the bacteria spreads to the fruits.

 

Avoid raw vegetables

Team leader Prof. Dipshikha Chakravortty from the Department of Microbiology and Cell Biology has advised everyone to avoid eating raw vegetables as much as possible. “While studies are now being done to see if the bacteria infect other vegetables used in salad in the same manner, the key is to avoid eating any raw vegetable in the current scenario,” she said to The Hindu.

Presently, the team is investigating possibilities of such infection in other salad vegetables as well as how fertilisers, pesticides and climatic conditions might influence the bacterial growth.

With the extension of the lockdown the crisis of migrant labourers and daily wagers has just grown bigger due to uncertainty and fear of future. In the migrant colonies, slums and for people in the villages hunger and desperation is building up day by day. This is high time we step up our efforts to support our people who are in dire need of food and hygiene essentials to survive the pandemic, Covid-19.

After the India-wide lockdown, a lot of jobless migrant workers are stuck in cities with hardly any resources while many started retreating back to their villages. With the loss of livelihoods, a large number of them are now struggling to support their families.

Goonj activated its pan India teams and a pan India network of partner organizations and volunteers in urban and rural India. This network, built over the last two decades, helps them learn from the ground, reach material quickly and review and adapt strategy periodically. Intensifying this network has helped Goonj reach and start work across 17produced states/UT in the last three weeks.

Goonj’s focus: 

Majority of the Covid-19 relief work by non profits right now is in the metros and cities but Goonj is the only non profit that is also simultaneously focusing on the people in the villages and the ones stuck on highways or somewhere.

Goonj is targeting daily wagers, migrants and other vulnerable groups, who even traditionally are left out like the disabled, sex workers, LGBTQ community.

“COVID-19 is a crisis, yes…But, it’s also an opportunity for us to build the society anew. Not ‘for’ the people…but, ‘with’ the people. And in the process, we will build ourselves too.” – Anshu Gupta, Founder-Director, Goonj.

Direct Monetary and Material Transfer

Wherever Goonj got the permission to open their centres for packing and disbursement of relief material kits, they are creating a kit consisting of 20-30 kgs material including dry rations, masks, sanitary pads and other hygiene material and reaching them to people, as per needs and as per regulations with all safety precautions. This kit will help a family survive for 30 days.

Information till 10th April 2020:

  • Distributed 15,100 ration kits reaching thousands of people
  • Reached 17,700 families
  • Supporting 12 community kitchen across India with 16,600kgs of ration
  • 77,800 food packets provided to migrant laborers and daily wagers walking on the roads across the country.
  • Provided direct financial support to 32 organisations
  • Made 42,800 cloth face masks
  • 24,900 cloth sanitary napkins produced
  • Produced 1500 litres of organic sanitiser

In Goonj’s processing centers its trained team of women are making cloth face masks and cloth sanitary pads (MY-Pads), keeping all the precautions and with the permission and cooperation of the local authorities.

In this lock-down phase if you are facing any difficulty getting sanitary pads or you are running out of stock, here’s a detailed but very simple process of making Cloth Pads at home created by Goonj. “This is how we make Goonj MY Pads.” This is how our mothers and grandmothers turned their spare cloth into pads.

This disaster, unlike any other, is unprecedented in its scale and impact and that’s why we all must do our bit with Goonj to continue its relief work for millions of people in this still unfolding long-tailed disaster.

The need is huge.. We are there.. Need You too !!
