Aug 6 (Reuters) – Roche said on Thursday it launched two new tests to detect cyclospora, as U.S. cyclosporiasis cases ​climbed to record levels this year ‌making the foodborne-illness outbreak one of the largest in the country’s recent history.

The Swiss healthcare company is collaborating with its subsidiary, TIB MOLBIOL, for supply ‌of ​the tests.

Here are some details:

• ⁠Roche’s two PCR ⁠tests, which detect pathogens by identifying their genetic material, can find cyclospora and other gastrointestinal parasites.

• The test portfolio allows laboratories ​to choose between screening for one, three or six parasites across different testing platforms, ⁠helping them tailor costs ⁠to their needs, TIB MOLBIOL ​CEO Marcus Droege said.

• Earlier this week, U.S. ​health authorities said they widened their probe ‌into a cyclosporiasis outbreak tied to iceberg lettuce from central Mexico after detecting cases in six additional states, raising the total ⁠to 15 states.

• So far about 6,358 cases have been reported from 15 states with at least ⁠278 hospitalizations, ‌according to the CDC and ⁠FDA. The agencies’ surveillance, however, lags ​state ‌reporting by several weeks.

• Cases ​have risen ⁠steadily across the United States in recent months, according to the U.S. Centers for Disease Control and Prevention, with reports from 47 states.
