Most effective Listeria Practices
When working in Factory that deals with pork production, what is the most common place to find Listeria and how is it monitored. If high levels are found what is the most effective way of getting rid of it.

Hi Kev,
The answer likely relates to yr type of production, eg if you make RTE, the monitoring will particularly focus on the environment post cooking.
The typical response is to construct a risk zoning scheme so as to implement a sampling plan prioritised to nearest potential food contact contamination surfaces > less likely contamination sources. The subsequent focussing is then refined based on the results.
Some areas are often foci for Listeria build-up such as drains but it depends on yr various layouts/routes of contamination/existing sanitation procedure. It's called Risk Assessment.
There are many listeria-oriented environmental zoning designs on this forum, eg -

Afaik (I'm not in USA) there is a barrage of FSIS Guidance documents for this topic.
addendum
One more relatively readable FSIS/Listeria ref. for small Plants which someone else posted here recently -

Hi everyone, I don't know if this could help.

I would also try the following documents for inspiring night time reading.
Yes, some of the literature is old, but still stands. Like other countries I'm sure, Australia takes its time to update its literature.

Hi Theresa,
Thks yr attachment which is particularly oriented to Healthcare/chilled foods. From memory, there have been several L.mono incidents in this UK domain in recent years.
Contains a lot of interesting stuff which also relates to food manufacturing but i did notice a few practical oddities, eg there are numerous recommendations to maintain chilled food below 5degC. There is also a comment that the rate of growth of L.mono at 8degC is double that at 5degC. But the document fails to mention that in UK the legal requirement for commercial refrigerators allows a temperature up to 8degC. (One of the differences to USA i believe although in practice ??)
