3,300.  

 

Context would be helpful, but assuming that this is a result, that would be the count of the bacteria.

 3 300 cfu (colony-forming unit) per g or ml or cm3 etc.

If it is result for aerobic bacteria - result is acceptable for many products, but if it is for e.g. Listeria - result is very bad.

The "micro" word / World is of course not necessarily restricted to bacteria.

 

Cheese anyone ? :smile:

Hi Apologies

 

Yes this is to bacteria, just needed to know interpretation before I go on me course to understand Logs etc.

 

>2.5 Log CFU/cm2  - Please interpret, would be most grateful.

 

Is there a paper I can get hold of for Red Meat (Slaughter & De-boning) legal limits etc I could use in the mean time. :spoton:

I can help with first bit.

 

See this link -

 

http://ncalculators....-calculator.htm

 

Put 2.5 in top box

Put 10 in next box down (I am assuming yr source is using logarithms to base 10 which is very highly likely)

 

Answer = 316.22 cfu/cm2  in normal numbers


Kind Regards,

Hi

 

Just a quick one if I may

 

In the red meat industry, for TVC on environmental at what levels should I be checking for?

 

Currently I am working to 1000, however they have set the lab up to reject 200000 and I think having a warning at 1000 internally is crazy. On specs they have put less than 5000000 - what's this all about?

 

I'm confused

Hi aps,

 

I'm confused also.

 

What do you mean by "environmental" ?


Kind Regards,

Hi aps,

 

Thks for comment.

 

Unfortunately I'm still confused.

 

do the numbers you mention refer to plate counts for swabbed  food contact surfaces or meat sampled (swabbed?)  from carcasses or ?

 

What are the units - cfu/cm2 or cfu/gram or ?

 

If for meat, where do these numbers come from ?  I could not see any similar limits for meat in the UK / MIG manual.

 

PS - all the  numbers look (far) too high for a cleaned/sanitized equipment contact surface if referred to cfu/cm2.


Kind Regards,

 

Charles.C
