Jeni's Splendid Ice Creams in Ohio once gain stopped its production facility and retail location after investigation showed potentially lethal food-borne bacteria in its factory.

According to a statement from Jeni's chief executive, John Lowe, the regional ice cream maker has closed its plant in Columbus this week after finding listeria during a routine swabbing.

It has been told that Jeni's has been closely monitoring and testing its equipments after detecting the bacteria in its ice cream in April that forced the company to recall all its products and close its 20 retail locations and the production facility.

As per experts, listeria is a persistent bacteria that has crippled multiple ice cream makers, including Blue Bell Creameries, in the last year. They said the potentially lethal bacteria can enter a factory, for example, from the bottom of a shoe and can linger for years.

Blue Bell, a top national ice cream brand that is quite popular in the Southwest, has been trying to determine how listeria could have contaminated products at its plants in Texas and Oklahoma.

Blue bell started to recall its products in March and eventually removed all of its products from stores in April.

Jeni's after imposing first ban resumed its production on May 13 and reopened its stores none days later. The company since then has been testing each batch of ice cream for listeria before sending it out for sale.

Mr. Lowe, said, "So it is with complete confidence that I can say all of the ice cream that has been served in our shops since reopening on May 22 has been safe and is 100 percent listeria-free".

Lowe did not disclose where in its facility it has found listeria. The company is investigating where and how it got inside.
