An inmate at Mt Eden remand prison has been isolated after contracting measles on Sat 27 Jul 2019. The man and his cellmate are in isolation, and only staff who are immune from the contagious disease are working with them.  The sick prisoner did not leave the prison or have any visitors during the exposure period. The prison has almost 1000 inmates, and about 500 staff. Corrections are taking particular measures to monitor the 120 other prisoners who were in same 2 units as the man last week.

Nationwide, 54 people contracted measles last week -- the largest number so far this year [2019] -- with 50 in Auckland, mostly in the Counties Manukau area.  From last month [Jun 2019], health authorities in Auckland started giving out the measles vaccine at one year instead of 15 months in an effort to curb the region's outbreak of the disease.  There was one case each in Waikato, Hawke's Bay, Capital and Coast and Canterbury.

About 1/3rd of all cases are children under 9 years old, and the next most common group are people in their 20s.  About 85 percent of those infected are people who have not been vaccinated.  In total, 407 people have been confirmed to have had measles in New Zealand this year [2019]. The disease has been on the rise across the world in recent years, with cases tripling worldwide.

Seafood lovers have been warned to be careful with raw mussels after an outbreak of foodborne illness.  New Zealand Food Safety announced on Fri 21 Jun 2019 that it has seen an uptick in the number of people contracting food poisoning from _Vibrio parahaemolyticus_.

Most of the people who got sick ate commercial grown mussels harvested in Coromandel. Symptoms are stomach cramps, watery diarrhoea and sometimes nausea, vomiting and fever. There are concerns the strain affecting people could be unusually aggressive.

"It is possible that the strain of _Vibrio parahaemolyticus_ is unusually aggressive, which may mean that even low numbers could cause illness," NZ food safety director of regulation Paul Dansted said. "Additional testing of mussels and the waters that they are being grown in is also underway to help us understand why this has happened. The mussels at the centre of the outbreak were all bought in their raw state, in the shell. They are not the mussels that can be bought in plastic pottles. Those mussels are cooked and marinated and are not affected."

NZ Food Safety says people need to be careful when cooking mussels and heat them above 65C [149 F]. It also advised washing hands after handling shellfish and to avoid cross-contamination between raw and cooked shellfish.  [Byline: Katie Fitzgerald]
========================
[It is important to stress that _Vibrio parahaemolyticus_ is naturally present in marine waters and does not imply sewage contamination, as would be the case with _Salmonella_ spp. or _Escherichia coli_. It is commonest in warmer waters such as those of the American Gulf Coast, but warmer waters in more northern climates such as in Washington State, Alaska and British Columbia, accentuated by global warming, can also be associated with shellfish-associated _V. parahaemolyticus_.

Indeed, eating raw shellfish only during months containing an "r" in its name may decrease eating them during the warmer months (May, June, July, and August), but only in the Northern Hemisphere (it should be reversed below the equator). However, since global warming has occurred, and with the shellfish being shipped quickly from warmer to colder areas, the old adage is not very helpful anymore. - ProMED Mod.LL]

Another 7 Aucklanders contracted measles over the weekend [15-16 Jun 2019], bringing the total number of cases in the region to 115.  Auckland Regional Public Health Service (ARPHS) announced the new cases on Monday afternoon [17 Jun 2019].

The Auckland region is experiencing an outbreak of the highly contagious and potentially life-threatening viral illness.  The majority of cases have been in people from West Auckland.

Last week [week of 10 Jun 2019], ARPHS and the Ministry of Health announced the vaccination age would be brought forward in the region, to 12 months.

In a post on the Immune Advisory Centre website [<http://www.immune.org.nz/hot-topic/measles-overseas-and-new-zealand>], ARPHS also said it would be changing its response in the next fortnight, "as contact tracing is not stopping the spread of the virus."

The most recent figures from ESR [Institute of Environmental Science and Research ], the science agency which tracks measles notifications, show there were 195 cases across the country as of [7 Jun 2019].  [Byline: Hannah Martin]

Wellington, June 15, 2019 (AFP) - A powerful 7.4 magnitude earthquake stuck near the uninhabited Kermadec islands northeast of New Zealand Sunday, the US Geological Survey said as authorities monitored for signs of a tsunami.   New Zealand's civil defence organisation said it was monitoring the situation and if a tsunami was generated it would take at least two hours to reach the country.   The Pacific Tsunami Warning Center said "hazardous tsunami waves from this earthquake are possible within 300 km of the epicentre along the coasts of the Kermadec islands."   The earthquake struck at 10:55am (2255 GMT Saturday) some 928 kilometres (575 miles) north-northeast of the New Zealand city of Tauranga in North Island at a depth of 34 km.

67 confirmed _Salmonella_ cases and 2 probable cases have been linked to sprouts consumption in New Zealand. Illness onset ranged from 23 Dec 2018 to 1 Apr 2019. 66 of the cases became ill between 23 Jan 2019 and 25 Jan 2019. 17 people required hospital treatment.

In the wake of the outbreak, GSF New Zealand [produce manufacturer] recalled certain Pams, Sproutman, and Fresh Harvest brand sprout products. GSF New Zealand said the recall was due to a "production process concern." Regarding the _Salmonella_ outbreak, New Zealand's Ministry of Health reported that "_Salmonella_ Typhimurium phage type 108/170 was the causative pathogen identified from cases, sprouts, and spent irrigation water tested in this outbreak. Subtyping using multiple locus variable-number tandem repeat analysis (MLVA) and whole genome sequencing methods were performed on isolates to confirm cases in the outbreak as well as the outbreak source."

The recalled sprouts had best before dates of 31 Mar 2019 to 4 Apr 2019.

Fresh Harvest branded sprouts were sold throughout the North Island at Countdown, Fresh Choice, and SuperValue. Pams Superfoods Super Salad Mix was sold throughout NZ. Other brands of Pam sprouts were sold on the North Island. Sproutman branded sprouts were sold throughout NZ.  [Byline: Jory Lange]
==================
[A number of significant pathogens, including _Salmonella_, _Listeria_, and enterohemorrhagic _E. coli_, have been linked to transmission from ingestion of a whole variety of different kinds sprouts in the USA and elsewhere.

The following is a relatively recent review on outbreaks caused by sprouts:
Dechet AM, Herman KM, Chen Parker C, et al: Outbreaks caused by sprouts, United States, 1998-2010: lessons learned and solutions needed. Foodborne Pathog Dis. 2014; 11(8): 635-44.

Abstract
--------
After a series of outbreaks associated with sprouts in the mid-1990s, the US Food and Drug Administration (FDA) published guidelines in 1999 for sprouts producers to reduce the risk of contamination. The recommendations included treating seeds with an antimicrobial agent such as calcium hypochlorite solution and testing spent irrigation water for pathogens. From 1998 through 2010, 33 outbreaks from seed and bean sprouts were documented in the USA, affecting 1330 reported persons. 28 outbreaks were caused by _Salmonella_, 4 by Shiga toxin-producing _Escherichia coli_, and one by _Listeria_. In 15 of the 18 outbreaks with information available, growers had not followed key FDA guidelines. In 3 outbreaks, however, the implicated sprouts were produced by firms that appeared to have implemented key FDA guidelines. Although seed chlorination, if consistently applied, reduces pathogen burden on sprouts, it does not eliminate the risk of human infection. Further seed and sprouts disinfection technologies, some recently developed, will be needed to enhance sprouts safety and reduce human disease. Improved seed production practices could also decrease pathogen burden, but, because seeds are a globally distributed commodity, will require international cooperation." - ProMED Mod.LL]
