This bacterium does not require any particular nutritional or environmental factors for growth. The bacteria can also grow in substrates with a low water activity of 0.86, over a wide temperature range of 7 to 48 C, and at pH values ranging from 4.2 to 9.3 (2).
Several studies in other countries have investigated the potential paths of transmission of this dangerous strain by human carriers or environment, such as transport and packaging, contaminated hands of workers, and the contact of infected respiratory secretions with seafood products (5,6,7,8).
