In 2011, approximately 95,500 cases of human salmonellosis were recorded. endstream endobj startxref Click this to : Click this to : Some serotypes are only found in one kind of animal or in a single place. This means that, while not able to multiply in many processed foods, if contamination is present, it can be difficult to eradicate. They may also survive well in acid foods and resist dehydration. %%EOF of labs No. �B�����ց�����u�X�h_;�3�:��E @ea���3�|&#�Ci�V5HWY�9oV�e~ꦲ\�z)����L�Go����ttmp*�̖�}Y���N�88�1:4i��:�"� ol��Ox�P��V�� ��p�1ojX�-�ìX��nf6���EV�jsҙ����z���M;�p]��G�6�h�ρAq%oR��a�xz3�M�b���Ỵ�S8YP��&AZ��Ŭ�C -����+:��*?i��Z�C�ύ��R�����eC vt8S"&gA����Ƃw;`D���-!l����[��GS}#��ã Testing can help guide treatment decisions.
