Spread Rate
Tuberculosis was detected in 3 separate herds in 2007. Parts of California have been downgraded from Accredited Free to Modified Accredited Advanced. In the absence of management, TB will likely slowly spread throughout the herd.
3
Spread Amount
Since 2002, California has twice lost its Accredited Free status. Due to TB's ability to survive for a long time in the wild in a number of environments, it has the potential to affect most of California's herds.

Ecological
Has the potential to switch hosts and infect cats, elk, bison, and other animals. However, with a sophisticated eradication program, which California has, the spread is unlikely
2
Agricultural
In areas with an eradication program, infection is usually limited to 1 or 2 animals per herd. Yet, these eradication programs are onerous and expensive. Major trade implications.

Health
There is little risk of TB passing to humans if the meat is cooked correctly and if the Dairy products are pasteurized correctly. California has strict testing facilities, which have kept the public safe from transmission.

Detection
In developed countries, few infections become symptomatic; most are diagnosed by routine testing or found at the slaughterhouse.
4
Control
Its large number of possible hosts, the fact that it often arises in densely populated communities (such as a cow herd), and relative resistance to many disinfectants can make it difficult to control.

Notes

Entry
There are strict legal prohibitions for trading animals infected with TB. What keeps this from being a "5" is its prevalence in wild animal communities, which are much harder to regulate.
4
Control
Eradication is mandated.
5
Outreach
It seems that California does a good job at keeping the public and its farmers well educated about the risks and regulations for TB.
