The study, published in the journal Applied and Environmental Microbiology, found that liquid from broken and torn leaves can boost bacteria growth by more than 110 percent while the veggies are still in sealed bags. Popular ingredients found in ready-made salads across the United Kingdom and Ireland were tested, including baby green oak, cos, red romaine, spinach, and red chard.

Lead scientist Dr. Primrose Freestone, from the university’s Department of Infection, Immunity and Inflammation, told the Telegraph, “Salad leaves are cut during harvesting and we found that even microlitres of the juices (less than 1/200th of a teaspoon) which leach from the cut ends of the leaves enabled salmonella to grow in water, even when it was refrigerated. These juices also helped the salmonella to attach itself to the salad leaves so strongly that vigorous washing could not remove the bacteria, and even enabled the pathogen to attach to the salad bag container.”

She said the study emphasized the need for salad leaf growers to keep up high food safety standards, as even a few salmonella cells in a salad bag at the time of purchase could become many thousands by the time the product reaches its use-by date.

“We found that even microliters of juice (less than 1/200th of a teaspoon) which leaches from the cut ends of the leaves enabled salmonella to grow in water, even when it was refrigerated,” said Freestone. “These juices also helped the salmonella to attach itself to the salad leaves so strongly that vigorous washing could not remove the bacteria, and even enabled the pathogen to attach to the salad bag container.”

Environmental activists have stopped up a pipe that is gushing toxic waste into the Mediterranean Sea.  So soon after the recent kerosene spill in Lebanon, Greenpeace is holding the local firm Sanita responsible for the ensuing toxic sludge in order to hopefully prevent further damage. Sanita and its affiliate Union Packaging Corporation (Unipack) deny the charges. Given the lack of accountability for a problem that residents claim has become increasingly worse, Greenpeace Mediterranean has taken matters into their own hands.

The environmental advocacy group affixed a banner to the offending pipe that says, “so the disaster stays with us,” a spoof on Sanita’s motto: “so the beauty stays with us.”

Also a subsidiary of INDEVCO, Unipack’s Regional General Manager Imad Khoury claims ownership of the blocked pipe, noting that Sanita is the sales wing of the organization. However, he denied charges that their waste is being inappropriately handled and passed the buck to the municipality.

Despite an official warning from the country’s environment ministry issued last September, Unipack told the paper that they only received the warning a few days ago and that steps had already been taken to address the ministry’s concerns.

Greenpeace has meanwhile requested that Sanita submit a full environmental audit in order to better gauge the affect of the toxic waste on the Mediterranean coastal environment.

Anecdotally, it doesn’t sound good: resident Joseph Rizkallah told The Daily Star that the waste which stretches five kilometers north and south of its original discharge spot in Halat imperils the local community’s health.

Scientists from the Holy Spirit University of Kaslik echo Mr. Rizkallah’s concern as traces of lead, copper, manganese and even harmful bacteria such as salmonella were discovered in samples collected near the site.

Halat’s mayor Charles Bassil also refuses culpability, as is actively pursuing a campaign against Sanita and Unionpack, the paper reports:

This is not acceptable, he said… there should be a stronger movement against the pollution; we demand implementation of new policies, we should know what pollutants are being dumped in the sea. Citizens have a right to live in a clean environment.

Greenpeace has issued its list of demands to the duo, which the Communications Officer Raefah Makki hopes to have answered by mid 2011.
