Hi all..
Can you help me to determine the acceptable level of Bacillus bacteria in the environment EMP
thanks

Why do you envisage having significant Bacillus spp in your Environment ?

 

It is almost impossible to meaningfully respond to yr query without some knowledge of your Product/Process etc ?

I'm sorry, I work in the catering and warehousing sector

No problem, IMEX Bacillus spp is not a particularly common environmental contaminant of interest within food processing facilities hence my query in Post 2. The most well-known (food pathogen) species in this genus is B.cereus.

ok thanks but what is the limit for bacillus cereus ?

Hi suhaibalbadawi97,

 

I wouldn’t be getting hung up on Bacillus cereus, usually simply swabbing for indicators using a TVC and Enterobactericeae test are sufficient. I would also include Y&M’s if a product is susceptible to them.

 

Have a look at this guidance posted by Food Standards Scotland - Environmental Swabbing, I think you will find it useful.

 

“In a high proportion of cases a total count of aerobic mesophiles (TCAM, also commonly called a total viable count [TVC] or most simply a total count) is a suitable indicator. Using TCAM as an indicator is one of the cheapest tests offered by the testing lab, if a pour plate methodology is used.”

 

Other common indicators include Enterobacteriaceae - See Table 2 Recommendations and guidance for clean environmental surfaces. Criterium:

≤10 cfu/cm² for TCAM (TVC)

≤1 cfu/cm² for the Enterobactericeae

 

Kind regards,

 

Tony

Of course, depending on precisely what is in the unknown environment ++, Pathogens could also be involved in the EMPG,
