a stick of celery

Nature Scientists at the Michigan State University Extension and Department of Plant, Soil and Microbial Sciences have posted details of a new fungal disease which attack celery with devastating consequences:

"Celery anthracnose is caused by the fungus Colletotrichum acutatum. This specific fungus is known to infect other vegetables including pepper, tomato, and spinach. It was first reported as a pathogen on celery in Australia during the 1980s, and was first detected in Michigan in 2010. The common name of this disease is “anthracnose” and is shared with diseases of onions, tomatoes and cucurbits. However, anthracnose in these crops refers to diseases caused by other types of fungi, not the C. acutatum that infects celery.

"Symptoms include cupped leaves and twisted petioles with long and thin brown lesions (Figure 1). Other symptoms include development of adventitious roots. "

Prevention methods are included though it's pretty common sense stuff about washing everything and keep an eye out. A similar process as for human fungal infections then.
